| To start we want to measure curves of reflection coefficient versus density at the coupler for different phasings and launcher positions. Ideally we would like Langmuir probe density to change from 2E17 to 5E18 during LH pulse.
Next we would like to investigate the effect of localized gas puffing using the NINJA capillaries. Gas puff deuterium from NINJA LH_B (NINJA LH_D) capillary alone should affect coupling only on the bottom (top) of the launcher, and we should be able to see it with RF probe diagnostic. Point 1 - [3-6 shots] - Start with fiducial 1100715014. Density at probes was on average 1E18 at begin of LH pulse. Decrease nl_04 by factor of 2 and move plasma inward by 1 cm. Launcher 1mm behind limiter, 70-90-110 deg phasing 20kW per column. Point 2 - [1-2 shots] - For best coupling conditions, ramp power from 25kW to 75 kW per column in 3 steps during during LH pulse Point 3 - [4-8 shots] - Repeat points 1 and 2 with launcher 0.1mm behind limiter. Point 4 - [3-6 shots] - Gas puff NINJA LH_B 10psi when LH turns on. Launcher 1mm behind limiter, 90 deg phasing, 70 kW per column. Adjust NINJA pressure and timing to see effect on edge density and reflection coefficient seen by RF probes. Repeat best condition with NINJA LH_D only, and if time allows with both capillaries. |

Right gap will be adjusted to avoid any indication of ionization at grill. The flattop pulse length will be extended to 1.7 s to allow MSE to get pre and post OH calibrations. Density will be set as low as possible while avoiding locked modes. If conditions look favorable, LH power will be increased to minimize loop voltage, hopefully to 0 V. |

| Run summary for the morning session for MP 608
Today we were able to do most of what was planned. First two shots were used to optimize the density scan in front of the grill from ~4E17 to ~4E18. We were able to collect traces of reflection coefficient Vs density for three phasigs at two Launcher positions. The reflection coefficient improved as we pushed the launcher in. Study of coupling at different power levels turned out to be difficult because density increases with LH power. So we decided to move on to study of effect of localized gas puffing on coupling. The same discharges that had good coupling at low power tripped at high power. Localized gas puffing indeed helped coupling and with it we were able to reach the same level of reflection coefficient we saw at low power. The amout of localized gas puffing was enough to change the global density. After this run I am more confident to say that the reason of high reflections is very steep density gradients in front of the LH grill. I will run simulations to verify my hypothesis. Effect of localized gas puffing is very promissing but we should spend some time on optimizing the timing and the amount of gas. |

| The second part of this run, beginning with shot 18, was devoted to PM: MP463 - Reaching zero loop voltage with LHCD. As the name of the MP implies, the object was to try to optimize conditions for LHCD (coupling, power and density) with the aim to reduce the loop voltage to zero.
In the initial shot(18), the right gap was 2 cm and the density at the grill was approximately equal to the cutoff density. Hence the coupling was poor, the reflection coefficient high and the LH tripped throughout its "on" period. For shots 19-23, the right gap was set to 1.0 cm and coupling was good for these shots with power reflection coefficient of 20-25%. The best of these shots was 1100818021, where the loop voltage transiently reached 0.2 V although it rose during the shot to 0.5 V. About 500 eV of electron heating was observed with 700 kW of LH power. Interestingly, the reflection coefficient decreased during the shot to 20% and the coupled power rose accordingly. Importantly, the plasma density stayed reasonably constant during the LH pulse. With the promising result in shot 21, the LH power was increased to 800 kW (coupled) in anticipation of increasing the current drive. Unfortunately, the plasma density also increased due to the increase of the LH power, and less drop in the loop voltage was produced. On shot 23 some flashing was seen near the LH grill, coincident with the density rise and some spiking on P_rad. Thus the right gap was then increased to 1.5 cm for shots 24 and 25. Shot 24 reached a loop voltage of ~0.3 V transiently, and settled down at 0.5 V. Good electron heating was also observed (~ 500 eV). However in shot 25 the current was increased from 700 to 850 kA and the grill density dropped below cutoff, resulting in an extended period of trips. The trips stopped temporarily at 1.25 s, at which time a sharp drop in loop voltage occurred; however, the plasma density rapidly rose shortly after the drop in V_loop, the density at the grill rose and the LH again faulted for the rest of the LH pulse. On the next shot, shot 1100818026, the right gap was reduced by 4 mm and coupling was maintained throughout the LH pulse; however, the LH power produced a strong increase in density, doubling the central density from ~0.6 to 1.2e20 m-3. As a result, the transient drop in loop voltage was only 0.3 V. Based on the uncontrolled plasma density rises produced by the LH power, it was decided to try a double null equilibrium. Since time was running short, an USN equilibrium from the previous day was selected. The thought was that the cryopump might be more effective in controlling the LH produced density increase. Two shots were run, 27 and 28, and both disrupted, apparently due to application of the LH power. Finally, the penultimate shot was an OH only shot run for MSE calibration purposes, and the last shot(30) was a reload of shot 21 with the plasma current reduced to 600 kA. This shot ran well, had a decent reduction of loop voltage (to ~ 0.4 V steady)and good electron heating (~ 500 eV). The overall conclusion from this half day is that achieving V_loop = 0 requires higher P_LH/n than could be achieved on this day. The LH performed best at coupled powers at or below 700 kW and with plasma density remaining at or slightly below nL_04 < 4e19 m-2. Unfortunately higher power produced higher plasma density, which mitigated the usefulness of the additional power. Also, the best results were produced at currents at or below 700 kA. Higher currents also seemed to raise the LH-induced density rise. The complex interplay between current, gap, configuration, current and LH power needs to be better mapped out to find the best path for nulling the loop voltage. |

| The run began on time and proceeded with only 2 significant delays, both due to failure of OH2 lower to commutate. In the second failed shot, EF1 U also failed to commutate. The OH2 problem turned out to be due to a fractured lead in its commutation bank. The lead was replaced in ~ 30 minutes (after shot 7) and no further engineering problems were encountered for the rest of the run.
The startups were reliable and early runaways were non-existent. Scorecard: 30 attempts at plasma, 24 either full length or full length through flattop, 1 fizzle and 1 dud due to commutation issues, 1 unexplained fizzle and 3 disruptions, including 2 in switching to an USN equilibrium. |

| Aug 18 2010 01:16:38:750PM | 1100818014 | Orso Meneghini | NINJA LH_B 10psi 20ms at 0.6
Do not see local effect of NINJA puff Oh! Jim Terry reports we were not puffing from the right capillary. Problem fixed, repeat shot. |

LH starts tripping as soon as it reaches 600 kw total power. Langmuir probes see 0.4E18. Need to increase density at the grill. Doing so by increasing RCUR by 0.5cm. |
| Aug 18 2010 02:17:39:710PM | 1100818019 | Orso Meneghini | Logbook entry for Ron Parker
Right Gap reduce to 1cm |
| Aug 18 2010 02:42:27:147PM | 1100818019 | Orso Meneghini | Logbook entry for Ron Parker
Right Gap reduce to 1cm Good shot, 700kW LH no trip, good refco ~24%. |
| Aug 18 2010 02:57:52:917PM | 1100818021 | Orso Meneghini | Logbook entry for Ron Parker
Good shot! Low density Ne0=0.7E20-0.9E20 and high temperature Te0=3keV during LH pulse. High temperature is reached during LH pulse and goes back to 2.5KeV after LH turns off. Good sign we are damping in the core? Can see driven current and Vloop~0.3V. Reflection coefficient goes down throughout the shot to 20%. We are accessible (n||=1.5). ECE saturated. Pitch angle data from MSE is available. |
| Aug 18 2010 03:11:12:427PM | 1100818022 | Orso Meneghini | Logbook entry for Ron Parker
no trips, refco~24%, 800kW net. Vloop ~0.5V Density is strongly affected by LH, possibly due outgassing from LH. Repeat shot to see if density stays lower this time. |
| Aug 18 2010 03:25:42:070PM | 1100818023 | Orso Meneghini | Logbook entry for Ron Parker
few trips, refco~25%, 800kW net. Vloop ~0.6V Density is strongly affected by LH as high as ne0=1E20. Saw some flashing on the launcher (as usually observed at high power and high density), reduce gap by 0.5cm to avoid flashing and possibly preventing density to rise. Repeat shot with RCUR=RCUR-0.25cm. |
| Aug 18 2010 03:45:04:100PM | 1100818024 | Orso Meneghini | Logbook entry for Ron Parker
two trips, refco~14%, 900kW net. Vloop ~0.4V Density is again strongly affected by LH as high as ne0=1.1E20. We see some hot spots between col 16 and dummy. Change RXU=RXU+1cm to reduce leading edges on launcher. Increase plasma current to 850KA to increase core temperature and maybe keep density down a little bit. |
| Aug 18 2010 04:01:58:043PM | 1100818025 | Orso Meneghini | Logbook entry for Ron Parker
sevaral trips refco~80%. Then suddenly refco~20%, 850kW net. Vloop transiently reaches ~0.2V as soon as LH turns on, but then density increase due to LH itself makes it increase again. Increasing plasma current has probably changed the density decay lenght thus affecting coupoling. Increase RCUR by 1mm and repeat. |
| Aug 18 2010 04:12:26:960PM | 1100818026 | Orso Meneghini | Logbook entry for Ron Parker
One early trip. Refco~23%, 800kW net. Interesting modulation of LH reflection coefficient, not observed in other discharges. Modulation is observed on all RF probes. Density increase to Ne0=1E20 due to LH. This is not working. Switching to upper single null (modified version of equilibrium 1100817015) to try to control density. Low LH power (600 kW) to start. |

One early trip. Refco~23%, 800kW net. Interesting modulation of LH reflection coefficient, not observed in other discharges. Modulation is observed on all RF probes.

Distruption at about 1s (Matt reports thugsten). Reflection coefficient is high and increasing. 1.5 cm gap and density is high and we are pumping in upper single null. The recipie seems not to work. Next shot density will be set to 0.4E20. |
| Aug 18 2010 04:46:38:223PM | 1100818028 | Orso Meneghini | Logbook entry for Ron Parker
Distruption at about 1s. Reflection coefficient is high and increasing with LH power. Next shot will be ohmic to let MSE people verify measurements are not drifting throuhout the shot. |

Distruption at about 1s. Reflection coefficient is high and increasing with LH power. Next shot will an ohmic version of shot 21 to let MSE people verify measurements are not drifting throuhout the shot. |
| Aug 18 2010 04:54:44:663PM | 1100818029 | Orso Meneghini | Logbook entry for Ron Parker
Beautiful ohmic shot. Next shot repeat of shot 21 but with 600 kA current. |
