The documentation described and linked here is intended as the primary documentation set for the review of the PXL detector subsystem. It is primarily intended as a progress update from the CD-2/3 review held in July 2011 at BNL.
A webpage giving the documentation set for the CD–2/3 review may be found at:
http://rnc.lbl.gov/hft/hardware/docs/cd23/
A continuous set of updates can be seen in the monthly reports submitted to DOE. These may be found in eroom on the LBNL website:
Irradiation test results for the Ultimate 1 (MIMOSA 28) sensor may be found at:

A report on the latch-up environment measured at STAR may be found at:
http://rnc.lbl.gov/hft/hardware/docs/latchup/Latchup_in_PXL_DRAFT.doc
We conducted beam tests at the CERN SPS beam test facility to use a beam telescope constructed from Ultimate 1 sensors and measure the efficiency and accidental rates from the sensors. A report detailing our results may be found at:
