Meeting 2026_01_29

MCSE: Marc, Quentin, Pierre, Denizcan, Gregory
CERN: Federico, Stephane
Excuse: Athanasios

Indico: https://indico.cern.ch/event/1640006/

Agenda:

• Presentation layout DC/DC + LDO ‘patch’
• Planning mise en place ‘patch’ (piggyback)
• Upgrade BeamCam communication
• Quels besoin preparation pour CHARM du cote CERN ?
• Planning readiness ?

Questions:

• How long is the glitch/undervoltage?
• Filtering + LDO
  – same LDO as in proto1?
  – how are we sure it handles the issue ?
  – Is this only a patch or a final solution ?
• Long term solution: strategy

Pierre : nouveau collaborateur (aspect scientifique)

Piggy bag sur EBB power

• Logueur glitch down est dependant de la capa softsatart mais pas mesuree
• LDO LT3033 --> 95mv drop https://www.analog.com/media/en/technical-documentation/data-sheets/LT3033.pdf
• 0.5V de marge
• EQM pour cet ete

Mi fevrier reception carte + test (2 semaines)

• Firmware: upgrade fin Mars
• UDP: camera OK
• Interface haute performance
  –> ‘PC’ issue solved
  –> tous les packets !
  –> Initial specs: 10 Hz --> seems OK
  –> very positive news !!

Firmware

• API python env windows ~done and tested
• Idee API en C ou C++ pour plus de perf.
• Rappel initial deal:
  • API for local use of camera + registers/drivers list for CERN to implement in FESA when available/validated

Preparation CHARM (from CERN)

• Request access (March --> May 26 ?): B867 + CHARM
• Same setup prepared for November 25 pour CHARM:
  • VME / CTRP (Trigger) / alim lamp
  • Storage images

Planning

• Mid feb: recpetion piggybag
• End Feb: test OK @ MCSE
• Mid March: Visit CERN to:
  • mount the piggybags
  • download new software
  • pre CHARM testing
• Mid April: CHARM dry run
• W3 April: CHARM beam time (TBC)

14:00 → 14:45 Discussion

Speakers: Athanasios Topaloudis (CERN), Federico Roncarolo (CERN), Mr Marc Jeanmonod (MCSE), Stephane Burger (CERN), denizcan sarigul (MCSE), gregory treuthardt (MCSE), quentin bouille (MCSE)
