MP 523: Effect of Lower Hybrid Current Drive on Rotation Profile

The locked mode portion of the experiment was successful. The first shot of the day was a steady locked mode discharges with sufficient argon levels to provide a good wavelength calibration for Hirex-Sr.

Shots 2-6 were spent scanning the LH phase from -60 to -120. We were able to couple LH power but did not drive any significant current (V_loop was unchanged). No change in rotation was observed for these discharges. This result suggests that is the LH current drive (as opposed to heating) that is responsible for the modification of the rotation profile.

We then had a cell access to switch to the LH system to the 150-210 phasing range. Shots 7-11 were spent attempting discharges with LH phase ranging from 150-180. Unfortunately, we were unable to couple any LH power to these discharges. We then had another cell access to switch the LH System to standard phasing and spent the remainder of the day performing a current and field scan. The LH effect on central rotation and some key plasma parameters are summarized in the table below.

Field Scan
23 4.4 0.75 0.45 620 90 35
26 6.3 0.75 0.50 620 90 17

The results of these scan can be summarized as follows:
Phase Scan: The amount of rotation driven by the LH system was largest at a phase angle of 60 and decreased monotonically as the phase was increased from 60 to 120. No change in rotation was observed for negatively phased LH injection. It seems that the magnitude of the rotation change is determine by the amount of LH current driven and so the phase dependence should be seen as correlated not causal.

Current Scan: The magnitude of the rotation change did not seem to depend strongly on current. However, the time scale on which the rotation profile evolved increased with decreasing current.

Field Scan: The both the magnitude and time scale of the rotation modification seems to depend on magnetic field. The low field discharge (4.5T, deltaV = -35km/s) had a larger and faster change in toroidal rotation when compared to the high field discharge (6.3T, deltaV = -17km/s)

Machine ran well today with 100% startup and only minor tweaks in the gas. We had a couple of data system problems that cost us some time. Cell entries to change phaseshifters also cost some time, but was, of course, necessary. Lower hybrid system ran well, and Alex reported record rotation rate changes as seen on hirex-sr. Major difficulty for the phyop was trying to maintain the requested low densities (with little success). This might have been a good run to have the cryopump in operation.

On shot 24 we had a data system glitch --- no TF and magnetics data missing
On shot 27 the PF breaker pulled --- bad fuses found in OH2L lower --- ended run

Session Leader Comments

Feb 15 2008 09:44:32:297AM 1080215001 Alex Ince-Cushman Good locked mode discharge. Argon signal levels are sufficient to provide Hirex-Sr with a good spectral calibration and so we will move on to the Lower Hybrid part of the run.

Feb 15 2008 09:46:17:957AM 1080215002 Alex Ince-Cushman Lower Hybrid was set to -90 phasing. About 400kW were coupled at a duty cycle of about 50% and no effect was seen on rotation. There was also no change in loop voltage or li.

Feb 15 2008 09:46:53:533AM 1080215003 Alex Ince-Cushman Lower Hybrid was set to -60 phasing. About 480kW were coupled at a duty cycle of about 50% and no effect was seen on rotation. There was also no change in loop voltage or li.

Feb 15 2008 09:51:12:307AM 1080215004 Alex Ince-Cushman Lower Hybrid was set to -60 phasing with 580kW of LH coupled cleanly. Still no effect on rotation, li or loop voltage. We will move on to 120 degree phasing.

Feb 15 2008 10:01:33:800AM 1080215005 Alex Ince-Cushman Lower Hybrid was set to -120 phasing with 580kW of LH coupled cleanly. No effect on rotation, li or loop voltage. We will go back to 90 degree phasing for one shot.

Feb 15 2008 10:26:58:270AM 1080215006 Alex Ince-Cushman Lower Hybrid was set to -90 phasing with 450kW of LH coupled cleanly. A slight change in rotation (deltaV ~ -5km/s) was detected. Note: this is the same direction as the change in rotation with positive phasing. The sign of the delat-loop-voltage did change, but the sign of the delta-li stayed the same. We will now have a cell access and move to -150 to 150 phasing.

Feb 15 2008 12:07:39:273PM 1080215010 Alex Ince-Cushman Still no LH coupling at 150 degree phasing. For the next shot we will increase the density and move the LH launcher in slightly to try and improve coupling.

Feb 15 2008 12:25:09:750PM 1080215011 Alex Ince-Cushman Still no LH coupling at 150 degree phasing. We will now have a cell access to switch the LH system back to the standard phasing range.

Feb 15 2008 01:54:22:773PM 1080215012 Alex Ince-Cushman Lower Hybrid phase to 60 degrees with ~470kW coupled. The density is a bit too high and seems to have reduced the magnitude of the change in rotation. There is, however, evidence of a substantial increase in the impurity confinement during the LH phase (argon density doubled!)

Feb 15 2008 01:56:28:980PM 1080215013 Alex Ince-Cushman Lower Hybrid phase at 60 degrees with ~470kW coupled. The density is still a bit too high but the rotation changed was large (~-35km/s). Again there was a substantial increase in argon density during the LH pulse, which is suggestive or an increase in impurity confinement.

Feb 15 2008 01:58:01:510PM 1080215014 Alex Ince-Cushman Lower Hybrid phase at 60 degrees with ~600kW coupled. The density level was good. Very large change in velocity (~-40km/s). This is the new trophy shot for LH induced rotation.

Feb 15 2008 02:02:50:347PM 1080215016 Alex Ince-Cushman The plasma current was raised to 1MA. Lower Hybrid phase at 60 degrees with ~600kW coupled. nl04 increased to 0.5. The change in rotation was reduced to ~-20km/s. It is not clear if this reduction was caused by the increase in density or current. It also worth noting that the time scale of the rotation modification was substantially slower on this shot than the previous shot.

Feb 15 2008 02:48:25:053PM 1080215017 Alex Ince-Cushman Current at 1MA, density a bit too high (nl04 ~ 0.5), LH at 60 degrees, coupling ~630kWs of power. A -20km/s change in toroidal rotation was observed evolving on a relatively slow time scale. Substantial increase in Argon density during LH pulse.

Feb 15 2008 02:58:44:893PM 1080215018 Alex Ince-Cushman Current at 0.75MA, LH at 60 degrees, coupling ~630kWs of power. A -20km/s change in toroidal rotation was observed. Rotaion profile evolution is faster than previous shot.

Feb 15 2008 03:01:07:297PM 1080215019 Alex Ince-Cushman Current at 0.6MA, LH at 60 degrees, coupling ~600kWs of power. A -20km/s change in toroidal rotation was observed. Looking at the last 3 shots, there is a clear trend in the rotation profile evolution time scale with current (i.e. faster evolution at lower current).

Feb 15 2008 05:34:48:853PM 1080215020 Alex Ince-Cushman Current at 0.76MA, LH at 60 degrees, coupling ~650kWs of power. A -15km/s change in toroidal rotation was observed. Density at was too high (nl04 ~0.56).

Feb 15 2008 03:26:50:237PM 1080215021 Alex Ince-Cushman Current at 0.76MA, LH at 60 degrees, coupling ~630kWs of power. A very large (-40km/s) change in toroidal rotation was observed. For the next discharge we will reduce Bt to 4T.

Feb 15 2008 03:44:53:117PM 1080215022 Alex Ince-Cushman Current at 0.76MA, LH at 90 degrees and Bt set to 4t. Due to low density and low field, the LH coupling was poor. We will try again at higher field and density.

Feb 15 2008 05:36:17:463PM 1080215023 Alex Ince-Cushman Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 4.5T. Density at 0.45. There was a -37km/s LH induced change in rotation.

Feb 15 2008 04:44:22:733PM 1080215025 Alex Ince-Cushman Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 6.3T. Density at 0.45. No LH power coupled to plasma. Can be used as a fiducial shot.

Feb 15 2008 05:39:41:983PM 1080215026 Alex Ince-Cushman Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 6.3T. Density at 0.50. There was a -17km/s LH induced change in rotation. Comparing this high field shot to the low field shot (23) we see that magnitude of deltaV is smaller (-17 compared to -35). Also the rotation evolution is much slower for the high field discharge than for the low field discharge.

Session Leader Comments
Feb 15 2008 09:44:32:297AM	1080215001	Alex Ince-Cushman	Good locked mode discharge. Argon signal levels are sufficient to provide Hirex-Sr with a good spectral calibration and so we will move on to the Lower Hybrid part of the run.
Feb 15 2008 09:46:17:957AM	1080215002	Alex Ince-Cushman	Lower Hybrid was set to -90 phasing. About 400kW were coupled at a duty cycle of about 50% and no effect was seen on rotation. There was also no change in loop voltage or li.
Feb 15 2008 09:46:53:533AM	1080215003	Alex Ince-Cushman	Lower Hybrid was set to -60 phasing. About 480kW were coupled at a duty cycle of about 50% and no effect was seen on rotation. There was also no change in loop voltage or li.
Feb 15 2008 09:51:12:307AM	1080215004	Alex Ince-Cushman	Lower Hybrid was set to -60 phasing with 580kW of LH coupled cleanly. Still no effect on rotation, li or loop voltage. We will move on to 120 degree phasing.
Feb 15 2008 10:01:33:800AM	1080215005	Alex Ince-Cushman	Lower Hybrid was set to -120 phasing with 580kW of LH coupled cleanly. No effect on rotation, li or loop voltage. We will go back to 90 degree phasing for one shot.
Feb 15 2008 10:26:58:270AM	1080215006	Alex Ince-Cushman	Lower Hybrid was set to -90 phasing with 450kW of LH coupled cleanly. A slight change in rotation (deltaV ~ -5km/s) was detected. Note: this is the same direction as the change in rotation with positive phasing. The sign of the delat-loop-voltage did change, but the sign of the delta-li stayed the same. We will now have a cell access and move to -150 to 150 phasing.
Feb 15 2008 12:07:39:273PM	1080215010	Alex Ince-Cushman	Still no LH coupling at 150 degree phasing. For the next shot we will increase the density and move the LH launcher in slightly to try and improve coupling.
Feb 15 2008 12:25:09:750PM	1080215011	Alex Ince-Cushman	Still no LH coupling at 150 degree phasing. We will now have a cell access to switch the LH system back to the standard phasing range.
Feb 15 2008 01:54:22:773PM	1080215012	Alex Ince-Cushman	Lower Hybrid phase to 60 degrees with ~470kW coupled. The density is a bit too high and seems to have reduced the magnitude of the change in rotation. There is, however, evidence of a substantial increase in the impurity confinement during the LH phase (argon density doubled!)
Feb 15 2008 01:56:28:980PM	1080215013	Alex Ince-Cushman	Lower Hybrid phase at 60 degrees with ~470kW coupled. The density is still a bit too high but the rotation changed was large (~-35km/s). Again there was a substantial increase in argon density during the LH pulse, which is suggestive or an increase in impurity confinement.
Feb 15 2008 01:58:01:510PM	1080215014	Alex Ince-Cushman	Lower Hybrid phase at 60 degrees with ~600kW coupled. The density level was good. Very large change in velocity (~-40km/s). This is the new trophy shot for LH induced rotation.
Feb 15 2008 02:02:50:347PM	1080215016	Alex Ince-Cushman	The plasma current was raised to 1MA. Lower Hybrid phase at 60 degrees with ~600kW coupled. nl04 increased to 0.5. The change in rotation was reduced to ~-20km/s. It is not clear if this reduction was caused by the increase in density or current. It also worth noting that the time scale of the rotation modification was substantially slower on this shot than the previous shot.
Feb 15 2008 02:48:25:053PM	1080215017	Alex Ince-Cushman	Current at 1MA, density a bit too high (nl04 ~ 0.5), LH at 60 degrees, coupling ~630kWs of power. A -20km/s change in toroidal rotation was observed evolving on a relatively slow time scale. Substantial increase in Argon density during LH pulse.
Feb 15 2008 02:58:44:893PM	1080215018	Alex Ince-Cushman	Current at 0.75MA, LH at 60 degrees, coupling ~630kWs of power. A -20km/s change in toroidal rotation was observed. Rotaion profile evolution is faster than previous shot.
Feb 15 2008 03:01:07:297PM	1080215019	Alex Ince-Cushman	Current at 0.6MA, LH at 60 degrees, coupling ~600kWs of power. A -20km/s change in toroidal rotation was observed. Looking at the last 3 shots, there is a clear trend in the rotation profile evolution time scale with current (i.e. faster evolution at lower current).
Feb 15 2008 05:34:48:853PM	1080215020	Alex Ince-Cushman	Current at 0.76MA, LH at 60 degrees, coupling ~650kWs of power. A -15km/s change in toroidal rotation was observed. Density at was too high (nl04 ~0.56).
Feb 15 2008 03:26:50:237PM	1080215021	Alex Ince-Cushman	Current at 0.76MA, LH at 60 degrees, coupling ~630kWs of power. A very large (-40km/s) change in toroidal rotation was observed. For the next discharge we will reduce Bt to 4T.
Feb 15 2008 03:44:53:117PM	1080215022	Alex Ince-Cushman	Current at 0.76MA, LH at 90 degrees and Bt set to 4t. Due to low density and low field, the LH coupling was poor. We will try again at higher field and density.
Feb 15 2008 05:36:17:463PM	1080215023	Alex Ince-Cushman	Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 4.5T. Density at 0.45. There was a -37km/s LH induced change in rotation.
Feb 15 2008 04:44:22:733PM	1080215025	Alex Ince-Cushman	Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 6.3T. Density at 0.45. No LH power coupled to plasma. Can be used as a fiducial shot.
Feb 15 2008 05:39:41:983PM	1080215026	Alex Ince-Cushman	Current at 0.76MA, LH at 90 degrees 650kW, Bt set to 6.3T. Density at 0.50. There was a -17km/s LH induced change in rotation. Comparing this high field shot to the low field shot (23) we see that magnitude of deltaV is smaller (-17 compared to -35). Also the rotation evolution is much slower for the high field discharge than for the low field discharge.

Feb 15 2008 02:54:16:827PM	1080215019	Jim Irby	loaded 1080215014 and set Ip to 600 kA loaded plasma into rampdown --- density higher than shot 14
Feb 15 2008 03:01:08:670PM	1080215020	Jim Irby	loaded from 1080215012 (800 kA) loaded plasma into rampdown
Feb 15 2008 03:14:25:870PM	1080215021	Jim Irby	nl_04 request dropped below 2.5e19/m^2 beyond 0.3 s loaded plasma into rampdown --- lower density at last
Feb 15 2008 03:40:58:423PM	1080215022	Jim Irby	Bt to 4 T (110 kA) after 100 ms loaded plasma into rampdown --- 4 T Bt faulting on LH
Feb 15 2008 03:53:40:890PM	1080215023	Jim Irby	Bt to 4.4 T (121 kA) nl_04 request to 4.1e19/m^2 plasma into rampdown --- density higher, Bt higher Solid LH pulse
Feb 15 2008 04:17:57:780PM	1080215024	Jim Irby	Bt to 6.5T (175 kA) --- PLC limit set to 185 kA loaded no TF --- got PFs --- lost magnetics data
Feb 15 2008 04:24:01:300PM	1080215025	Jim Irby	repeat plasma into rampdown but very little LH
Feb 15 2008 04:32:51:483PM	1080215026	Jim Irby	repeat with LH plasma -- got a nice LH pulse
Feb 15 2008 05:00:23:190PM	1080215027	Jim Irby	Bt back to 5.4 T (150 kA). PLC limit back to 165 kA PF breaker pulled out --- into the power room bad fuses in oh2l --- stop run
