Engineering setup for Tuesday 24 April 2007 MP# 355: ICRF conditioning Session leader: S. Wukitch Physics operator: J. Snipes ECDC overnight in D2, pressure=2e-4 Torr. Rmin/Rdwell/Rmax = 44/45/103 cm. Bake at 60 C. The run will start at 09:00 and end at 17:00. Power systems as on 1070330008 A-coil configuration: normal [Dtop -Dbot -Jtop +Jbot] and enabled. Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid DISABLED (PG1) leave B-side upper as is Hybrid DISABLED (PG2) fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) leave NINJA as is with 20 psi D2 DISABLED Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo shutters Torvac setup: Gate valves open during pulse. ------------------------------------------------------------------------------- ICRF Setup: All transmitters in run-on by 8:30 am ------------------------------------------------------------------------------- Run plan: We plan to run plain vanilla 5.4T, Ip~1 MA, nl_04~0.9 target discharges and increase ICRF power to 1 MW per transmitter for up to 1 sec. Time permitting we will scan lower triangularity if the H/D remains low. Note: The power system setup is close but I would like 5.4 T (not 5.5 T), 1 MA (not 0.8 MA), and nl_04~0.9. We have not run one of these so-called standard plasmas since last year. The right gap is fine and the upper triangularity is low (.2) would prefer 0.3. A shot from last year that is closer is 1060613015 but if it is easier to modify based on 1070330008 then we will go that direction. If we need some USN discharge then 1060421007 is a good candidate.

The run went fairly well, though there were several delays for cell access to fix diagnostics and for power room access to fix the ICRF. There were also a large number of fizzles, particularly later in the day after when after shot 21 Lipshultz asked to have the gate valves closed for 300 sec after each shot. It seems that the next shot after a full length shot then fizzled apparently due to a large carbon emission in the startup. Perhaps, if those extra five minutes were used to pump out the extraneous gases after the pulse, fewer fizzles would result. However, this experiment was not done so it remains a speculation. There were some fizzles earlier in the day before we closed the gate valves after the shot, but the frequency certainly increased later in the day. The H/(H+D) ratio varied from about 0.08 to 0.2 during the shot, increasing during the ICRF. Ratty H-modes were created on almost all shots. Clearly, a good boronization would help to improve plasma conditions. Of 31 shots, there were 19 plasmas and 12 fizzles with no power supply problems, although shot 1 did behave rather strangely and disrupted at 0.3 s. The other plasma shots were full length, though shot 9 had a lithium pellet injected at 1.6 s that then disrupted the plasma.

Physics Operator Comments
Apr 24 2007 09:23:54:720AM	1070424001	Joseph Snipes	Shot 1: Loaded shot 1070413022 to get the startup. Then, loaded segment 3 from 1060421007 into segment 3 for an upper single null plasma and called all of the predictors for the magnetically determined quantities. Then, loaded segment 2 from 1060613015 for a 5.4 T, 1 MA, 9 x 10^19 m^-2 standard single null lower plasma, which is the plasma we will start with. TF breaker pulled during the shot. Plasma disrupted at 0.31 s with a huge D-alpha increase at 0.2 s.
Apr 24 2007 09:41:58:180AM	1070424002	Joseph Snipes	Shot 2: Reduced rate of rise of the density to see if that was somehow causing the problem. Good shot. Got some H-modes from 0.85 to 1.3 s. ICRF reached just over 2 MW.
Apr 24 2007 09:42:06:510AM	1070424003	Joseph Snipes	Shot 3: Repeat. Good shot. Similar RF performance.
Apr 24 2007 10:00:13:657AM	1070424004	Joseph Snipes	Shot 4: Enabled argon puff and extended it from 0.3 to 0.4 s. LPI enabled and set to inject a pellet at 1.6 s. Lab access to ""straighten out"" Thomson. Good shot. LPI did not fire for some reason. ICRF looks similar.
Apr 24 2007 10:16:20:677AM	1070424005	Joseph Snipes	Shot 5: NINJA puff set to start just after ICRF turns off. Try again to inject a Li pellet at 1.6 s. Fizzle!

Mar 13 2007 09:47PM (labombard) Brian Labombard Inner Lower Divertor Probe Array labombard Probe Array - LH yes All 6 probes on the lower hybrid launcher (tungsten, 1.5 mm projection) are operational. Mar 13 2007 09:46PM (labombard) Brian LaBombard Lower Hybrid Probe Array labombard Probe Array - OSD yes Probes at 10 poloidal locations (one 'ramped' and one 'flush') are operational. n,Te, particle flux reported every 10 ms. Mar 13 2007 09:45PM (labombard) Brian LaBombard Outer Lower Divertor Probe Array labombard Probe Array - UDIV yes 14 probes are operational ('ramped' geometry). n,Te, particle flux reported every 10 ms.Two high-gain channels are installed and operational for ECDC plasma diagnosis. Mar 13 2007 12:46PM (labombard) Brian LaBombard Upper Divertor Probe Array labombard Reflectometer yes Starting on 4/23, 60GHz and 110GHz are working. 132GHz is being tested. Apr 24 2007 01:54PM (dominguez) Earl Marmar Reflectometer dominguez,marmar Scanning Probe - ASP yes Perpendicular Mach probe head is installed. The drive is operational. Mar 15 2007 09:09PM (labombard) Brian LaBombard A-Port Scanning Probe labombard Scanning Probe - FSP yes Perpendicular Mach probe head is installed. The probe drive is now operational. Mar 13 2007 09:51PM (labombard) Brian LaBombard F-Port Scanning Probe labombard Scanning Probe - WASP yes A-port WASP successfully collected data on 04/04. Some intermittent open circuit on SE Electrode. K-WASP took data on 04/11. Both ready to scan as needed. Apr 12 2007 04:18PM (nsmick) Brian LaBombard Inner Wall Scanning Probe labombard,nsmick TCI yes NL04 at 71.04 cm from 3/9/07 calibration Mar 09 2007 05:47PM (irby) Jim Irby Two-Color Interferometer (TCI) irby,murray TS - Core yes 2 lasers, 8 polychromators + 3 old (and less accurate) spectrometers. Density is not calibrated yet. Temperatures from polychromators should be reliable. Apr 11 2007 12:24AM (jwhughes) Jerry Hughes Thomson Scattering - Core jwhughes TS - Edge no Fibers are in place; will attempt to optimize measurements starting 4/24/07 Apr 23 2007 06:14PM (jwhughes) Jerry Hughes Thomson Scattering - Edge jwhughes Vispec yes looking around 441.2 nm for Ar XIV (or for lack of) Apr 24 2007 02:55PM (agraf) Alex Graf Visible Spectrometer agraf
