1. Downtime work
- tagger restoration - couple weeks; tage recabling; 3 VME cpu needed; tage HV restoration; translation table for tage
- microstrip detectors - need to see if working and use for tage calibration; if does not work, will calibrate later using other microstrips (HPS SVT ?)
- trigger for g14 (HDIce) run, need to test level2 with new trigger version, or use previous one
- LabView-EPICS communication to be implemented (Chris Bass and Nerses)
- LAC: half of ADCs shows garbage, need to fix; TDCs were never tested after PRIMEX2
- no CC
2. CAEN visit
- DC HV replacement was discussed, 944 fast trip was important, will discuss how to implement it in sy1527
- sy1527 boards testing conditions were discussed, will set better cooling and use every other slot; max power per channel is 8W, for tests we'll limit it to 7W
- calibration boards for sy1527 will arrive in few month, JLAB personal was trained for calibration and repairs
- old sy527 system need new fans (6 big and one small) if we want to use them in a future
