CERN-Edinburgh Liaison

• FC at end of SEC: manual
• Network access: port free.
• N2 gas ? 
• -date for connection of SEC to our chamber: week 30. October, 2nd November alignment. 
• collimator in front of chamber ?? contact Jorge Alberto about beam tuning in general (maybe add contingency high energy point) ? cc Karl

look for 4 deliveries: 2 bags gain resistors, 1 box luvac, 1 box farnell

2) Parts to be prepared in Edinburgh

• Iris: no news should be done today
• spare feedthrough for cooling, to be done.
• Al degrader: we have 2x10, 2x15 um (hole in center and light checked). 6 um still to prepare, 20 um maybe. mounts to be delivered.  
• Photo diodes x2 along with degrader foil: PCB & photodiodes here. extra holes for ladder.  drawings there. making degrader foil holder.  target ladder remade.  Preamps, amps? ask Tom. Cocknell preamp tested. 20 mv/MeV (250 MeV max). maybe borrow some more amps from miniball. 
• Faraday cup SHV to SMA converter: needs to be glued together
• Window port for front of chamber? Peter to manufacture
• Extra ribbon cables are needed? need to check with calibration. Also need long ribbon cables. will be done today/tomorrow
• 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).
• 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 mount points are at workshop
• Adjustable feet to be produced for radial alignment: Toby, almost done
• degrading of 12C - on elog. 

3)Decisions / Analysis

• Alpha analysis: dE and HI detectors seem ok, We need spare cables for Detector to preamplifier. 
• Sort Routine — Ruchi +Alex+Tom
• Target ladder config finalization: 2 photodiodes, collimator (what size, we have 3 mm and 10mm), Beam viewer, 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 - all will be sent here
