<p>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. </p> <p>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)</p> <p>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)</p> <p>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)</p> <p> </p> <p>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. </p> <p>cryring bnc 13 - ring rf - aida5 ~ 500,000 rate</p> <p>cryring bnc 14 - e cooler voltage - aida3 ~ 80 rate</p> <p>cryring bnc 15 - shottky -aida2 ~2000 rate</p> <p>cryring bnc 16 motors - aida1 ~3 rate </p> <p>correlation info #8 appears to be added to the good events rate (attachments 4,5) ADC items (attachment 3)</p> <p>Waveforms 1.8*W attached for 20us, 200us, 2ms, 20ms</p>
