On 15/2/22 it was noted that the leakage current increases when the motors are moved IN. This is contary to tests conducted on 12/2/22 (elog 192) where no increase was observed. 

16/2/22: Servo motor and pneumatic used to move in by different differences with leakage current observed to increase linearly with distance moved in, measured using the potentiometer. (attachment 10)

After each movement the pulser width was measured for each of aida1,2,3,4. No change observed for aida3,4 with pulser width ~220 channels. Pulser width decreased for aida1,2 when moved IN. (attachment 11)

Noise on aida 2,3,4 appeared low throughout tests. Aida1 has a large noise peak when in fully out position. When moved fully in, the noise peak disappears (attachments 1,2)

 

Cryring signals for ring RF, electron cooler voltage and schottky added to the motors signal and fed into mac b to be read in daq as aida correlation info #8 signal. 

cryring bnc 13  - ring rf - aida5 ~ 500,000 rate

cryring bnc 14 - e cooler voltage - aida3 ~ 80 rate

cryring bnc 15 - shottky -aida2 ~2000 rate

cryring bnc 16 motors - aida1 ~3 rate   

correlation info #8 appears to be added to the good events rate (attachments 4,5) ADC items (attachment 3)

Waveforms 1.8*W attached for 20us, 200us, 2ms, 20ms
