STARPXL Project News
• Preparation for DOE yearly review at BNL in July• Primarily a project progress review with significant technical content.• A set of documentation for the PXL detector CD-2/3 is available at
http://rnc.lbl.gov/hft/hardware/docs/sensor_review/summary_v2.doc • Additional documentation for this review will be posted soon.
• New Virtex-6 based RDO motherboards.• Design is complete and testing has finished• 3 PCB architecture, new connectors, cables, 9U VME physical format.• Full complement of 10 assembled boards have been ordered for the
prototype run RDO. Expected delivery in 3 weeks.
• Significant Progress in mechanical structures.• See pictures next slide

STARDiscussion Topics
• Ladder testing results. • Implications of instability in thresholds and noise.• Any other suggested testing?• Are these effects understandable through the
analysis of the sensor design?• Ultimate 2 submission schedule.• Monthly phone conferences – propose a
schedule. (2nd Tuesday of every month?) Please check your recurring meetings)
