We pumped the watt-can to .1u's. Something strange that I can't explain went on with the readout for watt-can vac. On Monday at 0800 I pumped the watt-can to 1.9u's to do a ROR on it. During the day it rose at the rate of 0.2u's an hour, which is about double of what it had been. I had planned to record another reading at 0800 on Tuesday to determine the ROR. When I came in on Tuesday the watt-can readout was reading 0.6u's. This was strange. It was as if someone had rezeroed the meter. I asked around and no one had done this. This morning when we came in the watt-can was reading 1.0u. We pumped the watt-can for 15 minutes with the turbo on high to 0.1u. If anyone does or has done anything to affect the readout please let me know. In the meantime I am doing another ROR so please don't pump the watt-can unless you have to, and please record any readings in the logbook.

Preparing to power magnet again to tune up QPM after Walt's changes.  People wish to work on CMX miniskirt and under detector. Since we plan to stay below 500 A there is no hazard from field for either task. Harry Carter is supervising and I have explained the situation.   Therefore we are treating this as a "deviation" from the startup proceedure. Light and sign on the West end of the magnet is removed. Starting up.

<pre>Powered to 1000 Amps. Fast Dumped it to check instrumentation. 
 
 
TO DO LIST: 
 
1) Look at 1000 Amp dump data 
 
2)Discovered fast transient that trips QPM when PS is on and trip points < 1 volt... otherwise QPM is pretty well tuned. Walt will put in 0.5 sec delay in circuit as we used to have. 
 
3) Need to verify MKS is working properly... now at 0.4 and rising so maybe it is OK... check tomorrow.  Need to move it. 
 
4) Need to make axial position transducers work. 
 
5) Need to understand lead asymetry during discharge. (SC and gas cooled lead)  
 
6) Need to make cryo inputs to ASTRODAQ work 
 
7) Need to move voltage taps to LEAD A and LEAD B and add klixons to monitor bolted joints. 
 
8) Misc programming 
 
PLAN = Work on these in the AM tomorrow and power after lunch.

<pre>Checked out cryo inputs in astrodaq.   We were not seeing anything.   I found the following. 
  
  1.  Inputs were wired up to data logger, but the only the 
      magnet dcct was wired to these inputs, and it was wired 
      incorrectly 
 
  2.  All of the astrodaq inputs were wired backwards -- that is      
      a +5v input was read out as -5v. 
 
I would like to wire these inputs tomorrow AM.   I also need to install the conversion of cryo inputs from volts to appropriate units. 
 
not all dump bits are working properly either, I get no response from any of the nim bits.   That we should check tomorrow as well. 
 
Checked wiring box on diving board.   Axial strain guage inputs is NOT connected.   Expect to find it in the J4 input and it is empty.  I looked and could not find the cable.  Need to look harder tomorrow.
