EPD Commissioning 2023

While much of the commissioning activity has already begun and much is well-documented, this will be a "high-level" page to keep track of EPD commissioning for 2023.

There are several changes this year:
  • On the West side, all channels will be read out for every event via the DEP system, but the QTs will only be read out at low event rates
  • We now have four EQ crates instead of three (this is related to the above, but no need to explain).
  • Some of the QT32Bs have been replaced by QT32Ds.


To do:
  • By 5 May 2023:  The West EPD has been installed and uninstalled and reinstalled and uninstalled due to water leaks at the same location..... it needs to be reinstalled. - Tristan/Prashanth
  • By 5 May 2023:  Seven Patterns Test.  This has been done in February with imperfect results.  Needs to be re-done.  Discussion on email list - Maria with advice from elders
  • Before beam:  Based on previous test: - Tristan/Yevheniia
    • replace/repair MDR connections or diffRx boards
    • re-map dead QT channels
  • Before beam: When things settle down on the trigger side, have trigger group check DSM board mapping - Eleanor (Mike)
  • Before beam: VPED scan - Maria
  • Before beam: Online monitoring plots - rearranging due to 4 crate? - ??
