BIAS OK. TEMPS OK.</p> <p>Thresholds initially set to 100 keV.</p> <p>Rates in all FEEs are > 200 kHZ. Attachment 6.</p> <p>We then checked the pulser peak widths in aida14. --> 192 channels with 1 V 1x attenuation. at 700 keV threshold (attachment 3). At 100 keV threshold the peak width was significantly higher!!! ---> 385 channels (attachment 2)</p> <p>We checked the rates in the FEEs with the 700 keV thresholds (attachment 11).</p> <p>Furthermore, we checked the constant noise that appears to be present in the y FEEs aida02,04,06,08. This can be seen in attachment 8 and has been noted in previous elogs https://elog.ph.ed.ac.uk/DESPEC/727<br /> <br /> Info on current status of ion catcher: vacuum system is ON, electronics is also on (RF ~2MHz) on the side opposite to the DESPEC setup</p></td> </tr> </tbody> </table> </p><p> </p>
