Run Summary for run 1091211 MP 587a Olaf Grulke participated in this run remotely via Skype (from IPP Griefswald). This worked well. The goal of this run was to investigate the properties of blob/filaments parallel the the magnetic field. Since the filaments are known to be at least approximately aligned along the field (k_blob dot B~0), we have configured the fields in such a way as to map flux tubes for two filament-sensitive diagnostics that are separated both poloidally and toroidally. Once that mapping is achieved we plan to examine the (time-delayed) cross-correlations between the time-series signals of the two diagnostics. The pairs of diagnostics used were for part 1 - the outboard midplane GPI 2 array of views (measuring the emission fluctuations) and the F port scanning probe (measuring both I_sat and V_float) for part 2 - the outboard midplane GPI 2 array of views and the outer divertor probes at F port We were successful in making those mappings and doing so over a range of densities. The analysis of the cross-correlations has yet to be performed. The shot list for the useful shots is as follows: (Bt was 5.4 T in all cases.) PART 1 - mapping FSP to APD array of GPI See the mapping graphs in the individual shot logbook entries. There were 3 probe plunges at 0.9, 1.05, and 1.2 sec. The values below are evaluated at 0.9 s (1st probe plunge) shot Ip (MA) NL04 (x10^20) rho range of FSP scan that was mapped APD columns 006 0.664 0.63 12 mm 4 008 0.626 0.53 7-12 mm 3-4 009 0.626 0.55 7-12 mm 3-4 010 0.596 0.56 4-8 mm 2-3 011 0.577 0.54 1-5 mm 1-2 012 0.625 0.56 7-12 mm 3-4 013 0.603 0.56 7-15 mm 4-5 (reduced outer gap) 015 0.606 0.41 7-13 mm 4-5 016 0.610 0.60 5-12 mm 4-5 017 0.600 0.80(0.9@1.2s) 5-13 mm 4-5 (some APDs saturated) 018 0.595 0.82(0.96@1.2s) 6-14 mm 4-5 019 0.595 0.83(1.0@1.2s) 5-14 mm 4-5 020 0.559 0.82(1.08@1.2s) 0-8 mm 3-4 End of part 1: note we scanned the mapping from 0 two density ranges a) 0.53-0.56x10^20 for which n/nGr=0.22-0.25 and b)0.8-1.08 x 10^20 for which n/nGr=0.36-0.52. There was also a scan from rho=7-13 mm at 0.40x10^20 for which n/nGr=0.19 (shot 15). Part 2: For this part we were mapping between the outer divertor probes and the outboard miplane GPI views. We had to move the outer strike point into the slot in order to locate probes 8-10 at relatively large rho. Because I didn't appreciate fully the effect of the strike point movement with respect to the single mapping that had been found for previous shots, we found a mapping at lower current than was specified in the MP. We only realized at shot 031 that the lower current mapping had the flux tube going ~1.5 times around toroidally, instead of the ~0.5 toroidal transit that would give the shortest mapping from the probes to the midplane view. This means that the mappings that were achieved were from field-line lengths of ~8 m, instead of the shortest possible lengths of ~3 m. The cross-correlation at the longer lengths is presumably reduced from the cross-correlation at the shorter length. The magnitude and scaling of the cross-correlation vs field-line length is of importance for this investigation. Ideally, we should have started in the "short-connection-length" configuration. However, by the time I realized that we were in the "8 m connection-length" configuration, we did not have time to run the "short-connection-length" configuration. The analysis of the time-delayed cross-correlations is starting. The parameters for the divertor probe-to-APD array view mapping is as follows: See individual shot entries for the field-line mappings vs time for probes 6-10. shots 021-025 searching for good mapping shot Ip (MA) NL04 (x10^20) mapping 026 0.532 0.43 probes 7-8 now mapping to ~6 cm above the array center 027 0.420 0.43 probe 8 on array 0.7-0.8 s; probe 10 on array 0.9-1.2 s 028 0.480 0.41 probe 9 on array 0.9-0.93 s 029 0.468 0.63 probe 9 now ~3 cm below array center - raise current 030 0.480 0.66 probes 7, 8 (~0.87 s) & 9 (0.87-0.96s) on array at various times 031 0.537 0.67 probe 9 on array 1.3-1.4 s

The machine ran mostly well during this run, in which the density was varied from 0.4e19 - ~1.1e20 (nl_04) and currents from 400 - 700 kA. The only operating issue was vertical stability as the SL wanted a relatively large outer gap (2 cm). This led to 3 disruptions early in the run (Shots 3-5). Raising the upper X-point to reduce elongation prevented further disruptions, (except shot 14 which disrupted due to an injection.) Startup was based on shot 1091210033 and was robust, except for 2 fizzles on the last 2 shots -- the ~ 5:00 O'clock syndrome. Score card: 33 plasma attempts, no duds, 2 fizzles, 4 disruptions and 27 full length shots

The timing shows that for this edge from 0.5 to 1.5 usec should be SUBTRACTED from the F port 196 digitizer's time base, in order to match the APD digitizer's time base. Note the resolution of the F port 196 digitizer is 2.0 usec. X-correlation analysis gives the shift to be subtracted from the 196 timebase vs time as: time(s) shift (usec) 0.910032 1.00000 1.01008 1.50000 1.11012 2.00000 1.21017 2.50000 1.31021 1.50000 To check the timing between the FSP signals as digitized by the "fast" 216 cPCI digitizer at 5 MHz and the "slow" 196 cPCI digitizer can be checked since Brian records the same same from the FSP on both. I looked at the nodes EDGE::TOP.probes.fsp_1.g_1.p3:I_Fast_raw (recorded at 5 MHz by the 216) and EDGE::TOP.probes.fsp_1.g_1.p3:I_Slow_raw (recorded at 500 KHz by the 196) I find that I must ADD 43.5 usec to the timebase of the 216 (fast) in order for it to line up with the signal as digitized by the 196 (and which is 0.5 to 1.5 us ahead of the APD digitizer). This is shown in the two figures below: Note that the FSP signal as digitized by the fast digitizer has been shifted by 43.5 us in both figures! X-correlation analysis gives the shift to be subtracted from the "fast" timebase to match the "slow" timebase vs time as: time(s) shift (usec) 0.910032 -43.4000 1.01008 -49.2000 1.11012 -49.8000 1.21017 -54.8000 note the trend is for the shift to get larger vs time. If I investigate this further by looking over the entire time that is common to both digitizers (and has non-zero signal), I find that the two digitizers' timebases drift as a function of time. This is shown here: This seems to be a problem with the probe-"fast" digitizer since the "slow" digitizer does not drift in a monotonic way with respect to the APD digitizer, at least over the shorter time for which Josh's timing signal is digitized (0.5 sec for this shot) All of this means that (43 to 55)-1.7 usec must be ADDED to the timebase of the 216 "fast" digitizer to line up the timebase to that of the APDs over the time during which the APDs were being digitized.

Physics Operator Comments
Dec 11 2009 12:06:34:427PM	1091211001	Ron Parker	Shot 1 counted down at 9:00, off to a prompt start. The loaded shot is from yesterday, 1091210033, wuth X-point programming from 1031204009 Shot ran OK, need to open right gap from 0.7 to 2.0 cm. Reprogram Rcur for next shot
Dec 11 2009 12:07:08:507PM	1091211002	Ron Parker	Shot 2 ran well, outer gap ~1.45 cm, program Rcur to increase to 2 cm on next shot
Dec 11 2009 12:07:39:990PM	1091211003	Ron Parker	Shot 3 disrupted at ~1.4 s -- scanning probe? Elongation? Next: increase outer gap by 2 mm, raise ZXU by 1 cm.
Dec 11 2009 12:08:07:520PM	1091211004	Ron Parker	Shot 4 disrupted again, at same time. Next: Bring RXU in by ~ 1cm later in shot.

Dec 11 2009 12:09:04:927PM	1091211006	Ron Parker	Shot 6 ran full length, perhaps raising ZXU again did the trick (reducing elongation). Next: reduce density request to 6.0 from 6.5e19 (nl_o4). Cell access will cause a short delay. Also for nest shot, procedure dpcs_ftae2 will be activated.

Dec 11 2009 12:11:43:880PM	1091211012	Ron Parker	Shot 12 ran full length Current hit the programmed value but right gap fell short. We'll decrease the gap again, this time by ~ 4mm. Also current will be decreased by 20 kA (to 590 kA)
Dec 11 2009 12:04:24:443PM	1091211013	Ron Parker	Shot 13 ran full length. Next:Density will be reduced to 4e19.

Dec 11 2009 01:45:07:527PM	1091211020	Ron Parker	Shot 20 ran full length, a little ratty during heavy NINJA injection toward end of pulse. Next: Density lowered to 5e19 m-2, Ip set at 565.
Dec 11 2009 01:59:13:263PM	1091211021	Ron Parker	Shot 21 ran full length. Next: density lowered to 4e19, programmed current ramped slightly to try to maintain constant current.
