Minutes of Quick Calorimetry Meeting 5-11-99. Present: KWB, RMB, DJAC, PSF, BWL, ALL. PSF Found references to and carried out calculations on diffusion of Helium in glasses. Re working and cross checking calculations for presenting to meeting. This generated a discussion on possible sealing methods and how we would set up tests. RMB had noted that a partial pressure of helium of 0.025Pa would cause VPT failure while 50Pa would give sparking at 4mm electrode spacing. RMB Summarised results from Photonis VPT's to date, has communicated results to Photonis but no feed back so far. KWB Meeting to discuss HT with JC and MT, will be giving ECal talk to visit on Monday in test beam area. BWK Moving simulation jobs using CMSim from CERN to RAL. DJAC Working on trying to improve our crystal delivery situation. Peter Denes will visit RAL, possibility that Tony Lodge may be able to help with their design work. Bristol keen to work on VFE boards. Len working with Justin Greenhalgh on FEA thermal problems for EE. ALL Testing Photonis VPT's. Unpacked 5x5 from CERN, working on mechanics for mounting on traversing table in test beam. Assembling display for visit on Monday.Laurie Lintern 9-11-99.
