- Update on BCM Studies and Calibrations by Deepak
See Link. Checking Keithley Current Source with a Newly Calibrated Multimeter - Deepak Bhetuwal
Trigger/DAQ
- Recent update on Trigger/DAQ in preparation for Hall C Fall-2017/Spring-2018
commissioning experiments. Main work has been to clean up unnecessary cable, and re-route some badly placed cables
- EDTM electronics for HMS/SHMS hodoscopes has been set-up and verified to be working
- Live Times for the HMS/SHMS were very different at EDTM>500 Hz, this might be due to a
update on the HMS DAQ firmware. Steve Wood will pass by the Counting Room to help on this issue. See Link. Recent Trigger/DAQ Work -Carlos Yero
SHMS
Magnets
- characterize Q2 behavior : checking for cross-talk polarity asymmetries, linearity
- Dave Mack is skeptical about the errors obtained in the measurement of Q2 field using the Hall probe.
- The hall probe might not work as it should for such strong magnetic field gradients according to D. Mack
