no beam until 9pm.

at 9 we cycled the mft (hist-cyle.cycle) cince the ABS had been off for a long time, and the BLAST torroid and holding field had both been cycled.

had to restart the HV GUI because the wrong one had been started. the correct one is in: ~/degrush/MEDMdev/hvMainExpert.adl

ran tensor polarized deuterium from 10pm to 12am. there was a brief problem around 11pm with the target cell cooling down. it had gone to 'monitor' mode and the PID parameters were wrong. placed a call to HK and reset them to p=600, i=150, and d=50. set target to 'control' and things came back. HK reported that the hall probes had appeared very noisy prior to about 10:45pm, but had settled down.

noticed that acl0, acr1, tcr1 were empty in the onlineGUI. went back to an earlier trigger, and tcr1 and acr1 came back. acl0 is still missing.

good runs: 1345 (tensor+, waveplate out)
                    1348 (tensor+, waveplate in - cell temp. changed during this run)
            1349 (tensor-, waveplate in - cell temp. changed during this run)
