Schedule for Readout Boards • More than half of the boards (10/16 for each side) have been fabricated. Remaining boards should be finished by Friday. • One board of each type has been stuffed by the stuffing house and tested at BNL. Both work fine. Stuffing of remaining 9 of each started on Monday and will be ready on Thursday (7/20). Remaining boards will be finished about a week later. • Feed through connectors will be added at BNL and then tested. Test fixture being constructed to speed up testing (expect to take ~ 1 hour/board). • Gluing procedure for rohacell has been tested and works. Boards will be glued after testing. Rate will be 4/day. Expect first boards to be ready to send to Stony Brook ~ 7/26 • Will construct fixture to help facilitate installing boards on back of detector. C.Woody, HBD Working Group Meeting, 7/18/06

Gas Monitor • Gas Monitor arrived at BNL 7/6. Looks good ! • Have begun setting up Labview controls of spectrometer grating and current switch for picoammeters. • Other parts (phototube housings, windows, test cells, etc.) are being fabricated. Some are already finished, some will be ready within a week or two. • We have decided to add a small turbo pump to the spectrometer and mirror box. This will allow us to measure the gas transmission relative to vacuum rather than argon. With a relatively small modification to the gas lines for the argon, can also pump on test cells for calibration for vacuum transmission. • Estimate ~ one month to complete entire system.
