O'Grady, Paul Christopher Tue 3/19/2024 8:46 AM Good to know … thanks for the clarification, Chris. chris Kenney, Christopher J. <kenney@slac.stanford.edu> O'Grady, Paul Christopher Alnajjar, Dawood; Doering, Dionisio; Claus, Ric; Dubrovin, Mikhail Hi Chris, Your assumption has always been correct - until now. For ePixM each detector is composed of four mechanically separate chip pairs. These ASIC-"sensor" pairs are significantly more complex and hence risky and may have lower yield. These "sensors" are also limited in size to one lithographic reticle field. Sorry. But ePixM will need metrology. Thanks, Chris O'Grady, Paul Christopher <cpo@slac.stanford.edu> Kenney, Christopher J. Alnajjar, Dawood; Doering, Dionisio; Klaus, Ric; Dubrovin, Mikhail Hi Chris, Just to check: I had the impression these units of 4 asics (whether in a square or in a line) should be one solid piece of silicon which shouldn’t need metrology. Do I misunderstand? chris Kenney, Christopher J. <kenney@slac.stanford.edu> Alnajjar, Dawood; O'Grady, Paul Christopher; Doering, Dionisio Claus, Ric; Dubrovin, Mikhail HI Mikhail, I've performed a metrology on a module and will provide you with the file this week. Thanks, Chris Alnajjar, Dawood <dnajjar@slac.stanford.edu> O'Grady, Paul Christopher; Kenney, Christopher J.; Doering, Dionisio Claus, Ric; Dubrovin, Mikhail Hi Mikhail & Chris, Thanks for reaching out. The Pixel size is 50um x 50um, and we assume no large pixels at this point. Also there are no gaps between pixels. @Kenney, Christopher J. would you know if there are gap between the ASICs?

He needs to know pixel sizes (including things like “large pixels”) and any gaps between pixels/asics. Thanks! chris |

Dark processing and deployment
- epixm320_dark_proc -k exp=tstx00417,run=324,dir=/drpneh/data/tst/tstx00417/xtc/ -d epixm -o ./work -D
- dark run should have 3 steps for gains SH, SL, AHL
- raw (4-ASIC) panel shape: (4, 192, 384)
- constants are saved in repository (see location using command epixm320_dark_proc -h) per panel per gain range
- -D option combines gain ranges constants for pedestals, pixel_status, pixel_rms, pixel_min, pixel_max in shape (3, 4, 192, 384) and deploys them in the DB
Gain from charge injection
- TBD
