Be beam pipe Schedule

• VTX, FVTX, PHENIX Management & CAD signed-off• Current ETA from Brush Wellman:

• 6 mos. to gun-drill Be tube (by mid-Oct. 2009)• Final assembly and QA (by mid-Nov. 2009)

• Deliver to BNL and reship to Europe for NEG coating• CERN to handle Be section (SAES refuses)• SAES Getters does all the rest

• Install prior to RHIC Run-11 (summer 2010)

F- Ion Extraction Test Report 10/21/2008Dele Fayemi3M Electronics Markets Materials DivisionTel: (651) 737-8115Email: [email protected] of 3M Novec 7000 and 7200 subjected to neutron irradiation received from Los Alamos National Laboratory were tested to determine if degradation had occurred. Decomposition was quantified through fluoride ion measurements as described in the 3M test method: “Fluoride ion extraction – indication of thermal decomposition”. The irradiated fluid samples showed slightly elevated, but insignificant fluoride ion levels when compared to control samples.Test ResultsThe results of the test are given in table 1. Table 1

InterpretationThe in-beam samples recorded average free fluoride ion concentration of ~0.03 ppm. Though these are elevated fluoride ion levels compared to the virgin samples, these concentrations are much less than 1 ppm and indicate insignificant degradation
