Operators: degrush tavi ----

Started Taking data with ABS Hydrogen, Long field 500 A. Goal is to first take a couple of runs with level 1 coda config file "physrun" and then run level 2 trig configuration using "physl2t".

Empty Cell Rates:
BQMs : L=25, B=33, R = 12 , T =52 I=22.1 mA tau = 19.8 min
slits: +2, +0.4, +12., + 7.5 ligit = 1.1 e-8 Tcell=67 K

phys0= 120, phys1 30, phys2 120
TSL1A = 484
TSL2A = 30 (at 21 mA)
ABS RATES:
BQMs : L=46, B=54, R = 19 , T =85 I=21 mA tau = 13 min
slits: +2, +0.4, +12., + 7.5 ligit = 1.1 e-8 Tcell=67 K

phys0= 134, phys1 31, phys2 124
TSL1A = 500
TSL2A = 49 (at 21 mA)

Random Notes:
Was unable to open V14 with the holding field on due to field affecting valve's solenoid. Field was ramped down and then opened.

Warn Event and the online gui is currently broken (T.B. is working on it) therefore the operator must mak sure data all data is being taken (physics, epics, compton).

WC HV R30 has been turned off , LADS L154_R1_Down has been turned off

Coda hung once, serial connection to blrocf3 is bad which means that you must go down and hit the reset button if you cannot access it through telnet,

WC S/N are good. Better than 2:1 for all chambers.
