ADTimePix3

An EPICS areaDetector driver for TimePix3 detector from ASC.

Additional information:

• Documentation
• Release notes

Notes:

• Depends on the CPR verson 1.9.1.
• Depends on the json version v3.11.2.
• Developed with ADCore R3-11 and ADSupport R1-10 or newer.
• This has only been developed/tested on ubuntu 22.04, 20.04, 18.04, RHEL 7.9, RHEL 9.1 Linux 64-bit machines.
• This has only been developed for 2 x 2 chips layout and 1 chip tpx3CAM, since that is what I have access to now.
• This has been tested with serval version 3.3.0, 3.2.0, 3.1.0 and 3.0.0. Only most recent serval version(s) are tested extensivly.
• Driver is specific to Serval version, since features differ. Driver for Serval 2.x.y is in separate branch, and is not under current development
• The driver has been developed using TimePix3 Emulator, and real detectors.

Before compiling:

• Compile cpr
• Clone json

How to run:

• Under ADTimePix3/iocs/tpx3IOC/iocBoot/iocTimePix there is already a ready to use IOC for the TimePix3
  • run serval
  • Change the IP address in st.cmd or st_base.cmd.
  • Run ./st.cmd.
• There are CSS-Boy, screens under ADTimePix3/tpx3App/op/
  • Phoebus .bob screens have been converted/created but not yet included in the driver.

Adjust chip thresholds

• Optimize/equalize chips in the 'count' mode (not ToT)
• Threshold fine increase is closer to noise (you get more counts)
• Threshold fine decrease is away from noise, higher threshold in keV. (you get less counts)
• These threshold settings can depend on X-ray energy.
• After changing the thresholds take a background image to check that you do not get extra noise pixels.
