U. Of Rochester DOE Review, July 15-16, 2002: P. de Barbaro, CMS13 Lab 5 Factory HB Optics factory in final phase. Will be winding down in December. (Need to repair/replace megatiles for HB-16). Reduce staffing from 13 to 5. Continue to build optical cables for HB and fiber parts for optical decoder units. Factory will redirect to work on components for RBX’s, HV, LV, electronics components.

U. Of Rochester DOE Review, July 15-16, 2002: P. de Barbaro, CMS15 Other Optics tasks Improve performance of optical cables Task taken over from UIC. Problem: tests at CERN this summer indicated that cables are very hard to install and connect/disconnect. Solution: increasing slightly (1.5mils) hole size for alignment pins can improve connection/disconnection, without compromising RMS of light transmission

ODUs will be built at Notre Dame factory this summer (QuarkNet) HE RBX parts scheduled to be completed in September 02. HO Design starting this month. Will have a PRR at CERN during September CMS week. Plan to complete all RBX’s by March 1, 03

Installation and Commissioning of US CMS detector at CERN (Pawel de Barbaro will become US CMS Coordinator at CERN in March 2003)

U. Of Rochester DOE Review, July 15-16, 2002: P. de Barbaro, CMS26 Front End Electronics QIE chips at FNAL (first submission). Chips are ~ fully functioning. Front end noise being studied. CCA chips at FNAL. Problem with communication to chip. (Bug in layout solved by laser microsurgery). Seems fully functional! A chance that both CCA and QIE can skip a generation of submissions, have production parts by March 02. GOL (Gigabit Optical Link) Serializer prototype chip at FNAL. Being tested at 45 Mhz, works fine. (Normal operation 40 Mhz). VCSEL chosen, parts being ordered. Fiber optic cable plant being finalized. (Discussion this week at CERN).
