Summary of PQB Achievements and Challenges during HAPPEx-III Team Meeting

During the HAPPEx-III B-Team Meeting held on October 28, 2009, significant PQB requirements were discussed, highlighting achievements in charge asymmetry measurements in micrometers (µm) for position (x and y) and microradians for angle (slope). The summary addressed accelerator issues and performance for PVDIS, indicating that no additional PQB work is necessary in the Injector for PVDIS, while noting that more work is required for PREx. Other topics included Compton background, phase advance, BPM saturation, and injector drift.
