Entry  Wed May 2 16:28:16 2007, Doug Preddy, Normal Running, Energizing solenoid to 500 amps  
Power supply initially would not ramp up. I exercised the rate control 
selector switch and found that the power supply would ramp up at only the 
30 minute setting. It is ramping up at a rate of about 60 minutes.
Entry  Sat Jun 16 15:05:03 2007, Doug Preddy, Normal Running, Solenoid power lead temp problem  
Power lead temps rippling and increasing. I asked an operator to cycle 
HIC142. This seems to have fixed the problem (for now).
Entry  Sun Jul 1 16:09:37 2007, Doug Preddy, Normal Running, M9B:DP2 tripped off   
Diffusion pump tripped off and vacuum (and power lead temps) going up. I 
had an experimentor cycle HIC 142 at 4:15 this morning. When I got in 
today I restarted the pump and it is back to 6.0 x 10-7. Power lead temps 
also are going down.
Entry  Thu Jul 5 03:04:50 2007, Doug Preddy, Normal Running, Power lead problems  
The power leads temps are starting to cycle again. Earlier today M9 
experimentor cycled HIC142 to stablize the oscillations. They started 
again early this morning, so cycled HIC142 again. Oscillations died back, 
but are still present. Will try and warm the power leads later today when 
the experiment's sample is changed.
Entry  Tue Jul 31 07:53:57 2007, Kevin Trithardt, Normal Running, cycled power leads  
got a page for the power lead temp
came down and cycled the power leads.. did not seem to make a difference..

There are two strip tools saved:
coils

Entry  Tue Oct 2 13:02:37 2007, Doug Preddy, Normal Running, PLC problems  
While downloading new code for 2A PLC the M9 and M15 vacuum systems were 
shut off. This is due to the two systems piggybacking onto the 2A PLC.
When M9 Epics came back up there was no controls. Eventually I reset the 
local/remote switch (thumbwheel #100) to button #1 being on. Mike Leross 
added a text and light on the epics vacuum page that says "EPICS works 
only when green". If this light is not green, dial thumbwheel #100 and 
push button #1. Make sure the light comes on and you should have EPICS 
control back.

This caused a glitch in the refrigerator system. It did not trip it off, 
but it would have if the solenoid was energised. The panel showed 
compressor fault and the temps for TI121, and the powerleads all jumped.
This may be a cause for some of our unknown problems.
Entry  Fri Nov 23 08:35:37 2007, Doug Preddy, Normal Running, power lead problems  
About 10 hours ago the power lead temperatures started to fluctuate and 
climb.
I cycled CV142 and the Temps have dropped and stablized.

Entry  Mon Nov 26 09:45:43 2007, Doug Preddy, Normal Running, power lead problems  
Power lead temperatures were rippling yesterday afternoon. I asked one of 
the operators to cycle CV142.
The temperatures were rippling again this morning, so I cycled CV142.
Entry  Tue Nov 27 21:02:08 2007, Doug Preddy, Normal Running, power lead ripples  
power leads were oscillating tonight. John K. came down and cycled CV142. 
(Thanks John!) Temps settling out.
Entry  Wed Apr 16 15:12:01 2008, Doug Preddy, Normal Running, graphs to load 
There are three strip tools saved: coils powerlead startup
Entry  Mon Apr 28 09:03:22 2008, Doug Preddy, Normal Running, power leads warmed during weekend 
The power lead temperatures suddenly rose on Sunday morning. No rippling occured before the woarm up. I shut flow off this morning for about 10 minutes (until the LHe in went up to 30K) and then open the flow back up. The temperature seem to be recovering.
Entry  Tue Jul 15 08:47:13 2008, Doug Preddy, Normal Running, Screen grab of normal running july_15_08_0841.jpgjuly_15_08_0846.jpg
Solenoid was recovered on Sunday July 13. The power leads started to ripple slightly this morning, so I cycled HIC142. No real change.
Entry  Thu Sep 4 10:02:55 2008, Doug Preddy, Normal Running, ramping down solenoid 
Solenoid power supply will be turned off for Fall shutdown.
Entry  Sun Oct 5 11:12:48 2008, Doug Preddy, Normal Running, M9B:V1 interlocks and a IOC crash 
M9A:V1 was removed this shutdown. It's "in" limit is required to allow M9B:V1 to be opened. I have bypassed the interlocks on M9B:V1 until the M9A:V1 limits can be jumpered. Don Dale and George Clark have been informed. Also an IOC crashed so the data pages were not updating. Evgeny rebooted the IOC. All is now fixed.
Entry  Wed Nov 5 16:33:52 2008, Doug Preddy, Normal Running, sbplc light out 
On main menu the sbplc light was black. All vacuum systems looked good, but there was no control of any device. Jane reset the IOC. It is hosted by sundance.

Entry  Fri Dec 19 13:07:25 2003, Willy Andersson, Maintenance, To-Do list for M9SOL M9Blist3.txt 
I had distributed this list by email earlier this month. I have added
a few items at the bottom. I am posting it on the M9SOL Elog under
Maintenance. Some of the items may not be achievable or practical but
I thought it would be a useful first attempt at a To-Do list.
