George B., David B., Scot S., Yi Q. Eugene C.

Review task list

Power supply: Giles provided Alex at Danfysik with history charts (dumps and trips) of our solenoid testing results, the conversation started, he will report next time
PXI, Yi will move the system to the Hall, Scot will take care of that afterwards
SOE: 90% done, need some time for final testing
Missing resistance file for quench detector adjustment on halld_engineer/solenoid_controls/ - Yi will look into the snapshots, still need to determine the relationship between the dial value and the resistance
Method to control such a system. Current controllable potentiometer solution is not linear, other PFGA or simpler mechanical method? Or use PLC's DAC to correct the input voltage.
Install hall probe in the solenoid
He level probe wiring - Scot continue working on it

 Review task list
-. PXI grounding: 90% done
+# Power supply: Giles provided Alex at Danfysik with history charts (dumps and trips) of our solenoid testing results, the conversation started, he will report next time
+# PXI, Yi will move the system to the Hall, Scot will take care of that afterwards
-. Hall-prove location - between 3 and 4, permanent, as close to center as possible. Discussion between Mark, Tom, Scot and Yi
+# SOE: 90% done, need some time for final testing
+# Missing resistance file for quench detector adjustment on halld_engineer/solenoid_controls/ - Yi will look into the snapshots, still need to determine the relationship between the dial value and the resistance
-. LHe level probe, wiring issue - Scot

+# Install hall probe in the solenoid
-. Coordinating system time - send PXI time to PLC - Yi
+# He level probe wiring - Scot continue working on it
-. Sequence of Events (SOE) system done
-. More signals to SOE - refrigerator fault - firmware update - test/tweak code/ - David - in a week 85%
-. Ramp rate, front panel card fixed and installed, will test the power supply after installing the jumpers
-. Dump sequence - Giles talking to Dynfesik
-. Ground fault signal to PXI - Scot and Yi
-. Method to access old archive
