Cell Lockup and Pre-Run Checklist 
v102799 JHI 
Revised 02/18/05 GLD

. Check above, around, and below machine for following: 

. any tools left near machine 

. any large unsecured magnetic objects within a couple of feet 
of the igloo 

. objects such a ladders unsecured around machine or 
leaning on the igloo 

. cabling that is not properly secured 

. nitrogen leaks from boots 

. any large buildups of ice around the machine 

. heaters are all running and delivering heat to intended areas 

. heater hoses that have been removed from around ports

. check that YAG laser shutter is open 

. verify that cell exhaust fan is operational 

. RF 
. check SF6 and GN2 purge to RF components


SF6: 
D, E, and J 6" coax should be 17-20 psi 

J 9" coax should be 10-12 psi 

Record bottle pressure in OPS logbook

N2: 
D and E 9" coax (from stub tuner to 6" coax) should be 20 psi

D and E 9" coax (from switch to stub tuner) should be 2 psi 

. check that EFC front panel leds are in the proper state 

. in control room

. open bolometer shutter 


. enter vacuum and ECDC info in the computer logbook
 
******************************************************

MAGNET COOLDOWN PROCEDURE: 
Revised 2/27/08 GLD

. stamp log book & fill in all info

. Heat temps should be set to 35/35/35
 
. take RGA data
 
. If ECDC is not running and has been requested before the run, 
begin plenum purging steps now (page 1 and 2 of ECDC procedure) 
while working through the steps below 

. check that the LN2 pump is set to 3 psi 

. check that upper cover cooling is set to 75% 

. check that lower cover cooling is set to 0% 

. toggle offset update on voltage/current screen of Cryo. 
If offsets dont reset correctly, reset Ross relays and 5V/5A supply 
(note: If ECDC is running, leave tf ross relay disabled)

. check IGT and Mass 40 readings 

. set EF magnet cooling setpoints as follows 

EF1u,l to -175C 
EF2u,l to -167C 
EF3u,l to -167C 
EF4U manual to 35%
EF4L manual to 30%
EFCU&L to -180C 

. set the OH cooling setpoint to -167C

. verify that the valves you expect to open do so 

. If ECDC is not running and has been requested before the run, 
continue ECDC procedure now (page 3 through page 8) but skip 
RGA setup on page 3. 

. except for EFCs and EF2s wait until the EF coils are within 10C 
of their setpoints 

. check IGT and Mass 40 readings 

. set TFU, TFV, TFL cooling setpoints to -140C 

. wait until the TF regulates at -140C and verify that there are no 
increases in the machine base pressure or mass 40 on the RGA 

. set TFU, TFV, TFL cooling setpoints to -165C 

. after regulation verify that there are no increases in the machine 
base pressure or mass 40 on the RGA 

. set TFV cooling setpoint to -182C 

. set TFU & TFL cooling setpoints to -180C 

. reset i2t system 

. at time of lockup set CC_OUT cooling setpoint to -180C 

. at time of lockup set CC_INS cooling to manual at 30% 

. wait about 1 minute and verify CC_INS pressure is within 0.2 psi of 1.2 psi 

. after first shot set LN2 pump pressure to 8 psi

***************************************************************************

TORVAC AND DIAGNOSTIC SETUP PROCEDURE: 
Revised 2/18/05 GLD

.turn on ECE 
.open ZBolo
.verify "GV CLOSE IN PULSE" has been toggled off 
.turn on Ratiomatics and toggle AUTO RESTART
.setup gas system according to daily physop run plan
