<p>Email sent to Karl and Olof about </p> <ul> <li>FC at end of SEC</li> <li>Gain resistor package</li> <li>Network access</li> <li>N2 gas</li> <li>date for connection of SEC to our chamber</li> <li>collimator in front of chamber ?</li> </ul> <p>Next week call Karl. Daid will look at old Olof emails</p> <p>2) Parts to be prepared in Edinburgh</p> <ul> <li>- Iris under construction, add. stop so it does not close all the way. coming along nicely. might have to increase detector distance a bit for safety. no news</li> <li>spare feedthrough for cooling, to be done</li> <li>Al degrader: We have 15 um and 6&10 um in Edinburgh, Daid will check if light-tight. We will prepare one 15, one 10 and on 6, possibly backups. Make hole, we have frames. more frames</li> <li>Photo diodes x2 along with degrader foil: PCB & photodiodes here. extra holes for ladder. coming along. 2 diodes need a bit less than 2 space, 10 spaces in total, maybe 11. drawings there. Preamps, amps? ask Tom</li> <li>Faraday cup SHV to SMA converter: Peter on order</li> <li>Window port for front of chamber? Peter to manufacture</li> <li>Extra ribbon cables are needed? need to check with calibration. Also need long ribbon cables. Peter will make 2 new ones. Peter has bits</li> <li>Photographs and diagrams of experimental setup -- organized clearly for beam operators during tuning: add technical drawing on elog Peter will make it coherent. Safety Folder/Risk Assessment. Safety Datasheets (Ethanol). send to Karl</li> <li>Alignment -- 2 end caps and one target ladder mount for optics reflector (8 mm diameter?) For survey people. Peter: two ends are done, drawings for S2 and target ladder mountain points not made yet. </li> <li>Adjustable feet to be produced for radial alignment: Peter / Toby</li> </ul> <p>3)Decisions / Analysis</p> <ul> <li>Alpha analysis: dE and HI detectors seem ok, We need spare cables for Detector to preamplifier. </li> <li>Sort Routine — ask Tom</li> <li>Target ladder config finalization: 2 photodiodes, collimator (what size, we have 3 mm and 10mm), Beam viewer, We need to verify how many positions we have. 3 CH2 and 2 Carbon.</li> <li>Calibration of Target ladder positions. Peter / Daid</li> <li>CH2 and C sample choice. So far CH2 Target 1: 30+25 (480ug/cm2); CH2 Target 2: 16 (400 ug/cm2). Check combination 33+1+10. New Ch2 from Paul —> Check thickness asap!</li> </ul> Encoding: HTML ELCode plain Suppress Email notification Resubmit as new entry
