65 nm meeting

jeudi 9 déc. 2021, 11:00 → 13:00 Europe/Paris

Bat 20 - uElec (https://cern.zoom.us/j/69600555186?pwd=eVcxUTBnc2J0bWwyQ3RBM0ttZkN6Zz09)

 

• Test discussion, Yitao
  • report from test beam at DESY: A4, B4, C4, D4 got data
  • 2 triggering modes: scintillator or small DPTS
    • note that DPTS is smaller than CE65 => mostly DC-amp covered by trigger
  • event monitor developed in EUDAQ -> allows alignment check
    • CE-65 values crudely selected
    • alignment between ALPIDE & CE65 observed
  • noise analysis with TAF, some difference with or without beam
  • first look at hits from TAF (no correlation with tracks)
  • Note that the DAQboard used in beam is different from lab
    • clock is 40 MHz
  • next steps
    • continue a bit the analysis on clusters only with TAF
    • develop analysis with corrycreckan for correlation with tracks
  • Additional lab test before Christmas
    • AC-Amp need more systematic data
    • Suggestion by Andrei to scan the phase shift => need help from Cagliari here

 

• MOSS design, Fred, Xiaochao
  • mock-submission soon to be sent (without the new metal layers)
  • new PDK with 2 metal layers => potentially small impact on our part

 

• CE-65++ design, Andrei
  • first chip on its way with one pixel type
  • may not be fully complete but still good for mock-submission
  • next year the design of other variants should be easier
  • about 3.3 V digital IO? let's switch to the CERN way whenever defined

 

• MOST design, Szymon

  • quite some work to achieve before Christmas
  • but no show-stopper
  • impact of new PDK seems limited for Szymon's part

   

  * About test system for ER1 sensors
     - under discussion, DAQboard probably not suited for MOSS
     - for CE65++, DAQboard will need modification (hw and fw)
     - we should expect ~6 months for fabrication,
          so taking into account submission April = test ~October
  
  * NEXT MEETING January 6th, 10:30
