(During rampup) 137656 bdavis Nov 20 2013 15:55:42 Stong MHD (rampup) 138113 bdavis Oct 16 2013 12:56:24 very stable edge between 0.255 and 0.265 So, a L-H transition and then a H-L transition 138113 bdavis Oct 16 2013 13:22:44 large Dalpha emission at end of shot 138114 bdavis Nov 20 2013 15:57:34 Beam turns on near peak 138115 bdavis Nov 18 2013 09:02:59 abrupt suppression of blobs from 0.244-0.256 s, ~15ms after beam pulse ends 138115 bdavis Nov 20 2013 15:59:02 NB pulse around GPI peak 138116 bdavis Nov 20 2013 15:59:49 Beams modulation during GPI peak 138118 bdavis Oct 16 2013 14:28:21 suddenly quiet edge between .25 and .26 138748 bdavis Nov 21 2013 10:14:55 Gap is too large. ELM later on 138847 bdavis Nov 21 2013 10:18:35 Ripples after blobs 138855 bdavis Oct 18 2013 16:11:46 Looks like some ELMS during the Gas Puff 139054 bdavis Nov 21 2013 10:30:15 ELM 3 msec before peak (not shown in movie) 139059 bdavis Nov 21 2013 10:35:12 Beam drop out near GPI peak 139288 bdavis Nov 21 2013 10:37:13 broad ELM 20 ms before GPI peak 139289 bdavis Nov 21 2013 10:38:02 broad ELM 30 ms before GPI peak 139293 bdavis Oct 18 2013 16:19:58 large oscillations seen in movie; see 313.7 and 314.3. Not surprising considering the nature of the GPI averages trace. 139295 bdavis Nov 21 2013 10:39:52 ELM just before peak 139429 bdavis Oct 18 2013 16:24:27 Interesting blob shapes after movie time, seen in thumnails, like after .2948 139429 bdavis Nov 21 2013 10:42:25 funny Ne profile 139430 bdavis Oct 18 2013 16:26:22 large and bright structures moving downward at the beginning of the movie so makes the rest of the movie too dark 139430 bdavis Nov 21 2013 10:43:26 ELM at peak of GPI 139430 bdavis Feb 27 2014 13:58:39 Larger blobs go upwards inside the separatrix, but smaller ones do not As seen in http://nstx.pppl.gov/nstx/Software/Diagnostics/FC2010/GPI/GPIcompVy.html the larger blobs go up 2-4 Km/s inside the separatrix, but the smaller blobs have average Vpol of ~0. 139435 bdavis Nov 21 2013 10:47:19 Beam turns on near peak 139437 bdavis Nov 26 2013 10:29:32 Current ramping up, so grade B 139438 bdavis Oct 18 2013 16:30:14 Big flare at the end of the movie is a disruption The algorithm to find the maximum of the GPI signal didn`t work for this one. 139439 bdavis Nov 26 2013 10:33:29 no steady state 139445 bdavis Nov 26 2013 10:34:59 ELM close to peak GPI 139447 bdavis Oct 18 2013 16:39:50 Blobs sometimes move upwards, sometimes downwards. Sometimes break free. 139447 bdavis Nov 26 2013 10:36:28 too much MHD; Grade B 139504 bdavis Oct 18 2013 16:43:32 a lot of crescent-shaped blobs get ejected in the movie 139510 bdavis Nov 26 2013 10:42:38 funny Equilibrium (edge tilted); Grade B 139877 bdavis Nov 26 2013 10:43:32 lots of ELMs; Grade B 139881 bdavis Oct 17 2013 10:21:33 Wild pin wheel around 315.6 in movie 139885 bdavis Nov 26 2013 10:50:09 Not really in equilibrium; Grade B 139886 bdavis Nov 11 2013 13:36:06 Blob trails misleading. Extreme oscillation of brightness in whole band Since most of the light emitted stays in the band, normalizing (done for the Blob Trails, but not the movie) by dividing by average leaves residuals that show up in the Blob Trails picture as many randomly-oriented blobs. I don`t recall seeing such extreme oscillations in brightness as in this movie. 139898 bdavis Nov 26 2013 10:55:40 Interesting blobs, but edge not steady; Grade B 140523 bdavis Dec 2 2013 15:07:18 NB step up 7 ms after peak 140627 bdavis Dec 2 2013 15:13:53 GPI current good, but Ip not flat 140628 bdavis Dec 2 2013 15:14:37 ELM right before peak 141290 bdavis Dec 2 2013 15:24:14 L-H transition? 141309 bdavis Dec 3 2013 10:04:14 Very artistic looking. Waves and large "sun flares" coming off 141316 bdavis Dec 3 2013 10:14:18 Major disruption 141324 bdavis Dec 3 2013 10:17:45 Very quiet during gas puffing 141448 bdavis Dec 3 2013 10:20:32 Big ELM during Gas Puff 141449 bdavis Dec 3 2013 10:21:36 Big ELM during Gas Puff 141452 bdavis Oct 18 2013 13:38:34 Big excursion in Center Averages at 482 ms The movie just starts at this time, so only catches a bit of this. The rest of the movie looks very normal. 141457 bdavis Oct 18 2013 13:32:59 Looks like EFIT is way off until 485 ms 141458 bdavis Oct 18 2013 13:34:54 Plasma is to the right of the manifold! 141459 bdavis Oct 18 2013 13:27:40 EFIT broken between .481 and .490, so "peak" time changed to after this 141461 bdavis Dec 3 2013 10:25:57 ELM close to peak GPI 141462 bdavis Oct 18 2013 13:19:19 Big oscillation at the beginning of movie 141462 bdavis Oct 18 2013 13:19:43 Very fast downward motion of blobs 141462 bdavis Oct 18 2013 13:20:25 EFIT line goes crooked at 490.1 141741 bdavis Nov 12 2013 13:16:48 lots of downward slanting ripples Gives me the impression the camera is looking from the side! 141745 bdavis Nov 11 2013 14:15:13 Thomson data all zero -- Ben says shutters didn't open. 141746 bdavis Nov 12 2013 10:30:33 Blob trails shown in plot not evident in movie without normalization Looks like some very strong shear effects on either side of separatrix (best seen in FCplayer with normaliztion). 141908 bdavis Dec 5 2013 10:02:13 RF turns on near peak 141920 bdavis Dec 5 2013 10:08:50 RF turns on near peak 141921 bdavis Oct 28 2013 13:15:33 a big ELM around 220 ms 141921 bdavis Feb 27 2014 14:46:33 Bigger blobs have ~1Km/s larger downward velocity As seen on http://nstx.pppl.gov/nstx/Software/Diagnostics/FC2010/GPI/GPIcompVy.html the bigger blobs have ~ 1Km/s greater downward velocity than the smaller blobs 141990 szweben Oct 17 2013 09:00:59 test the movie is a bit too dim 142005 bdavis Dec 5 2013 10:16:51 Note that blobs before peak are inside Sep and those after are outside 142220 bdavis Mar 13 2014 11:21:05 very active and discontinuous edge Very interesting. Gives the impression of being very tilted and downward pointing. 142236 bdavis Oct 18 2013 12:41:37 Billows pointing towards source of gas puff 142273 bdavis Oct 18 2013 11:38:29 A lot of turbulent features that look more like plumes than blobs 142274 bdavis Oct 18 2013 11:39:24 Wild excursion after the peak
