Quickcal 30 Apr 1999

             Minutes of Quick Calorimetry Meeting  30-4-99


Present:    Austin Ball, RMB, DJAC, PSF, BWK, ALL.


ALL   Clearing out Lab 6 and 7 ready for building operations in Lab 6.
      Working on hardware for test beam magnets PC control.
      Rigged up ADAM units so that Andrew could test Labview control
      program, this was successful.
      Next week A/L.


PSF   Discussions with Dave Evans on resins and gas evolution problems.
      Working on JIF bid for ISIS irradiation facility.
      Still fighting spectrophotometer drift problems, seems to be 
      sensitive to dirt.
      Continue glue tests next week and preparation for irradiation of
      samples at Brunel Co60 source.


BWK   Continuing simulations at the Barrel/Endcap region using endcap
      size options (-3 and -6cm).
      Reconstruct hadronic jets (b and d) at eta 1.2-1.7 with one
      interaction length of copper behind and aluminium in gap to
      simulate cables, no significant effects in HCal.
      With single photons looked in the gap region with HCal added in.
      At eta 1.48 -1.52 the corner of the copper block is clipped.
      HCal sees half energy of photon with no copper block.
      Change radius of Endcap to +3cm and it looks OK but at TDR radius
      energy goes down to about 40%.
      Remove copper and energy can be reconstructed fairly well although
      resolution poor as it's the HCal.
      Next week more simulation and work for PPESP with Fred Wickens.


DJAC  Resources review board on Monday. Met with Russians on Tuesday
      to discuss Alveola's, price costing will be presented next week
      at ECal week. Yesterday J-L Faure has asked a French firm to quote
      for Alveola's.
      Next week, ECal week at CERN. 5x5 array at CERN.
