Email sent to Karl and Olof about 

  • FC at end of SEC
  • Gain resistor package
  • Network access
  • N2 gas
  • date for connection of SEC to our chamber
  • collimator in front of chamber ?

Next week call Karl. Daid will look at old Olof emails

2) Parts to be prepared in Edinburgh

  • - 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
  • spare feedthrough for cooling, to be done
  • 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
  • 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
  • Faraday cup SHV to SMA converter: Peter on order
  • Window port for front of chamber? Peter to manufacture
  • Extra ribbon cables are needed? need to check with calibration. Also need long ribbon cables. Peter will make 2 new ones. Peter has bits
  • 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
  • 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. 
  • Adjustable feet to be produced for radial alignment: Peter / Toby

3)Decisions / Analysis

  • Alpha analysis: dE and HI detectors seem ok, We need spare cables for Detector to preamplifier. 
  • Sort Routine — ask Tom
  • 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.
  • Calibration of Target ladder positions. Peter / Daid
  • 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!
