Temp OK Attachment 1. test - Pulser OFF.</p> <p> Rates somewhat worse than last night - probable contact on grounding of snout. Attachment 3.</p> <p> Histograms okay, some FEE64s now have hot channels. Attachment 2.</p> <p> 9/16 aidas < 20kHz - max rate 162k</p> <p> </p> <p>18:06 - powering down detector for the weekend. Overall system is fine, some channels (hot channels) definitely picked up noise, but condition is overall stable over three hours. See atachments 4-5.</p> <p> </p> <p><strong>TO-DO (<em>kicking the can down the road</em>):</strong></p> <p>- Some work to do on noise, but we might have to accept the situation as it currently is.</p> <p>- Implement bPlast trigger scheme. Set bPlast thresholds, get bPlast current draw undercontrol - observe AIDA noise.</p> <p>- Try different grounding configuration:</p> <p> - Grounding drain wires to frame. Observe AIDA conditions.</p> <p> - Reconnect 4V out to R&SRMP4040 common ground with PN 300 PSU as well. Observe AIDA conditions.</p> <p> </p></td> </tr> </tbody> </table> </p><p> </p>
