<p>15:40 reseated FEE64s adaptors of aida01, aida09, aida13 & aida16.</p>
<p>TEMP OK. HV OK. System wide checks all passed excl. aida07 ADC calibration, see attached.</p>
<p>Histograms and rates look same as previous, reseating aida01 seems to have worked. aida16 still unhappy.</p>
<p>re-reseated aida16. 16:19 - appears to have fixed the problem in the channel.</p>
<p>Pulser test + connected.</p>
<p>bPlast ground removed from frame.</p>
<p>To-do:</p>
<p>- Need clarification about links connected on AIDA n+n FEE64 adaptor boards. Currently, the situation is given by the attachment 8 & 9.</p>
<p>- Fix BB7 grounding, continuity between snout and frame observed.</p>
<p>- Pulser walkthrough for n+n, can do p+n when convienient.</p>

<p>18.30 Noted FEE64 ADC stats now significantly higher ( attachments 9-10 ) cf. earlier this afternoon (attachments 1-2)</p>
<p>DSSSD bias OFF. FEE64 power OFF.</p>
