Last bias 15/1/22 see previous elogs, max leakage current ~10 uA at 150V</p> <p>Detector bias increases well above 10uA for voltages as low as 30-40V. Optical windows covered, Y09 valves closed, large ion pump OFF and both ion gauges OFF produces similar results but with a slightly lower leakage current.</p> <p>Grounding and pulser cables removed from FEEs and jumper attached to nn bias adaptor card - no change. Bias module swapped out - no effect. NIM rack shows expected voltages (6,12,24) on multimeter.</p> <p> </p> <p>AIDA03 - disconnected. Behaves as expected. Get waveforms and pulser peak. Pulser peak FWHM ~ 70 channels, noise transients observed.</p> <p>AIDA02 - Not producing ADC data</p> <p>AIDA01,04,05,06,07,08 - Very high rates - noisy</p> <p> </p></td> </tr> </tbody> </table> </p><p> </p>
