The beamtime on July 21 is the final shift of the dec 2022 epix10ka calibration beamtimes. From the December beamtimes two primary problems were observed, the check mark problem for the small 10k's and 3 out of the 4 quads of the MFX 2M showing values that were too low after switching.

We believe the problem is due to the X-ray pulse arriving to early in the measurement cycle, and only partially within the ACQ window, For the upcoming beamtimes 4 detectors will be evaluated: epix10ka front facing (no. 27), epix10ka sidefacing 1mm Si, ePix10k2M.1, and a prototype of the ePix10ka non-ghosting ASIC (NG). For the first 2 shifts, the primary aims are (in order of importance):
