ADTimePix3

Notes

• Depends on the CPR version 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 extensively.

• 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

  1. run serval

  2. Change the IP address in st.cmd or st_base.cmd

  3. Run ./st.cmd

• There are CSS-Boy, screens under TimePix3/tpx3App/op/.

  1. 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.

CSS screens

The following is the CSS screen ADTimePix3.opi when controlling an ADTimePix3 camera.

The following are the CSS screens for features of ADTimePix3 detector

Serval 3.3.0 allows multiple raw streams (socket, .tpx3 file writing)
