Both HAM2 and HAM3 ISIs were locked this morning for alignment work. It was a good occasion to take look at the time series of the ISIs' Capacitive Position Sensors, and make sure that the locked/unlocked shifts were within requirements.
Maximum shift observed < 800cts*.The locked/unlocked shifts are within requirements**. Results are attached.
*:Calibration: 32768cts/mm
**: Acceptance Criteria (E1000309-v13, p28)
Absolute values of the difference between the unlocked and the locked table must be below 1600 cts
