Minutes of Quick Calorimetry Meeting  13-2-98.


Present:  RMB, BWK, ALL, MS.


BWK   Opal work earlier this week.
      Drafting Technical note on Monte Carlo of Endcap work.
      Generating simulation data, Alveola data can be changed in program.
      Will run program with various materials.
      RMB notes: 2500 CHF/Alveola in Carbon fibre composite, Ecole Poly.
      can do it for 1/4 cost in glass fibre.
      Technology FEA study for CF comp gives flexure of 12 microns which
      is over designed so some hope for glass fibre.


ALL   Magnet state in R5.2: The cooling circuit is OK now but on trying
      to bring on the power supply found various defects in the interlock
      system. Geoff Martin will be trying to sort this out this weekend.
      Clearing up Test beam area for safety committee tour next Monday.
      Started work to modify 4T armature for 1.8T tests, hope to complete
      next week.


RMB   This week gave talk on Opal to department and Ken Peach on future
      plans, for grants committee. DJAC gave talk for CMS.
      Worked on define deliverables for Memorandum of understanding.
      Next week A/L 3 days then return to prepare for Battle visit to CERN.
      Report from DCI: Chris Selby to make Brunel VPT test box for RAL.
      Talked to Electron tubes re. next iteration of prototype VPT's.
      They are considering his proposals.


MS    Working on test beam with crystals/VPT's comparing with field of 
      Opal test magnet on and off.
      First estimate looks like field effect is a factor of 2.
      Checked light yield in alveola wrapped in Tyvec and unwrapped.
      first estimate looks like 15% fall off unwrapped.
      Next week ISIS off so run LED tests.
