Due to curent lead temperature occilation Doug recommended warming up the 
current leads.

The leads were warmed up this morning then cooled back down. Power supply 
is ramping up now.. 2 1/2 hours start to finish.

Power leads cold again, power supply ramping up.

At 14:45.

Added two bottles of UHP helium to buffer tank.
Had no liquifation rate, so optimized Ti121 and HIC141 . Finally put TIC121 
into manual mode at 0.65. Power lead fluctuation died out and liquid 
started building. 
This morning changed TIC121 back to auto mode and played with it's setting 
to minimize the power lead and TI121 ripples. 
TI121 ripples seem tied to power lead ripples.
System seems stable enough to energize the solenoid.

PIC 229 was down to 10.8 bar this morning. PIC 229 was trying to open CV211 
to charge the system. I realized that in restoring the control to CV211 I 
did not get the wire into the connector properly. Went back up to the 
compressor building  and reconnected the control wire to CV211. pressure is 
back to 11 bar. TI121, LHE in and liquid level ripples are now all reduced.

System was ramped up to 500 amps yesterday at 14:00

Power leads are being monitored with the strip tool graphs. I saw the temps 
go from having a ripple to almost no ripple, but starting to increase in 
temperature. I also noticed that the flow had dropped to 200 mm. I power 
cycled hic142. This resulted in an immediate drop in temperature, an 
increase of flow to 250 mm, and a slight drop in the LHe level. The temps 
seem to be stable, with only a slight ripple.

Same story as yesterday. Ripples dieing out, flows down to <200 mm, temps 
increasing. Turned HIC 142 down to 0.4 then back up to 0.75. Temps dropped 
quickly. Then turned HIC 142 to 0 and back to 0.75. Temps dropping, flow > 
250mm. Did not let negtive lead >10K, so would not have caused a trip.

TIC 121 into auto mode. 

power lead ripples increased over last couple of days. They are quickly 
dieing out now and the temps are startint to increase. PL flow is down to 
<180mm. I will power cycle HIC 142.

Power cycled HIC 142 with solenoid power at 400 amps. Flows > 240mm and 
temps have dropped.

should be ready to run.

Tuesday 14:55

Removed jumper on back of PIC 901. This jumper should be off during
normal operation so the solenoid/refrigerator is protected from bad vacuum.

The solenoid has been re-started as of August 19. It was cooled down and 
energized over the weekend. Sunday night at 9:30 it tripped due to 
negative power lead going above it's set point. The system stopped flow to 
the solenoid, but kept the compressor and cold box running. While starting 
flow to the solenoid, we got a high pressure trip. I came in and restarted 
the compressor, after Curtis located and reset the over pressure 
interlock. The solenoid is cold and energized as of 3:30 pm yesterday. It 
is still stable as of now.

The power lead flows had dropped to 210 mm this morning. I increased HIC142 
from 0.8 to 0.83. The flows are back to <250 mm and the temps are back to 
LHe in-10.8, PL-Pos-11.1, PL-Neg-8.9

Lhe ripple has started. 10.9-11.4K PL-Pos also has a smaller ripple. Both 
flows down to 230mm. Cycled HIC 142 and the ripple disappeared. 
Put TIC121 into auto mode.

The LHe in and PL-neg temps have been building up a ripple over the last 
few days. Curtis cycled HIC142 Friday evening at about 5:00. I just had 
the Main control room operator (Peter) cycle them again. The ripples died 
right out. 
Originally the ripple was 10.8-11.4K on the LHe-in and 8.9-9.2K on the PL-
Neg. They are now steady at 10.7K and 8.9K.

Power lead temps starting to ripple at a 1.5min period. PL flows are 
both>250 mm.

Flow to power leads dropped to <80 mm. Cycled HIC142. Temps dropping, flows 
>250.

Flow is down to <190 mm. temps are starting to climb. Cycled HIC142

power temps as follows:
LHE_IN 23
PL_POS 36
PL_NEG 31
Flow <90mm 
cycled HIC 142 off and on in 1/2 hour.
