<p> Tues 15/12/15</p> <p>Swapped previously tripped detector (3131-11) on to kaptons already in place for (working) 2977-15 and attempted to bias</p> <p> - i.e. made no changes (FEEs, or jumpers etc) to the known working setup of 2977-15, just replaced the detector with 3131-11</p> <p> > still trips at ~6-7V</p> <p> > conclusion: He's dead Jim.</p> <p> </p> <p>Took some measurements of rough max positions of DSSSDs from the FEEs with the current 90cm kaptons (pictures in attached PowerPoint and PDF)</p> <p> - Vertical EURIKA support to centre of EURIKA ~ 60cm</p> <p> - AIDA Cu cooling pipe to end of snout ~ 75cm</p> <p> - Base of snout to end = 57cm</p> <p> - Min distance from end of snout to inner most FEE (horizontal FEEs) ~ 92cm</p> <p> - additional 6cm per extra adapter</p> <p> - Further DSSSD can go from base of snout ~ 54cm (60cm from Cu pipe)</p> <p> - limiting factor is kaptons to nnaida5+6 (bottom stack). Still a few more cm slack in the other kaptons.</p> <p> - For kaptons in 4th horizontal connector (furthest slot in 2nd adapter), detector 48cm from base of snout.</p> <p> - For kaptons in 8th horizontal connector (furthest slot in 4th adapter), detector 36cm from base of snout.</p> <p> </p> <p><u>Note (PCS):</u> In disconnecting things to check ground connections, and when putting AIDA away before I left, I noticed ~20% of the network cables are of the shielded variety. I know this didn't seem to make any difference in the setup at DL, but I don't know how concerned you are about this and if you would suggest changing them in future.</p> <p> </p>
