This is a successful first plasma startup run after in-vessel work... shot 30-31: Got 2 in a row full-length 600 kA plasmas. shot 32: 1 nearly full-lengh 800 kA plasmas. shot 33: post-5 pm fizzle. First plasma attempt was shot 8 after some power tests. PG4 and IC_EF4U were tweaked several times to increase the chance of getting full-length plasma. Note: TF cooling was slow ( ~ 18 minutes interval between full length shots)

After this shot, looked at Mirnov coil data and noticed that spectrogram for BP1T_GHK was too quiet. Went in cell. Ohmed out BP1T_GHK, BP2T_GHK, and BP3T_GHK. 1 and 2 are opens, 3 had 8 ohms. NOTE: BP3T_GHK may not be dead - see next logbook entry. :( They were working on 9 April.
