Bat 20 - uElec
https://cern.zoom.us/j/69600555186?pwd=eVcxUTBnc2J0bWwyQ3RBM0ttZkN6Zz09
- Tests
- about new irradiations: Serhyi will investigate with Hartmut, not sure we have CE-65 there
- Yiato status:
- partly resume work (from home!) on Beam test analysis
- now work on telescope alignment
- Goals from Auguste: find out the detection efficiency (which relies only on seed signal)
even with the crude CE65 analysis (absolute cut on pixel value) - leave the detailed handling of analogue signal
- MOSS design, Fred, Xiaochao
- feedback from foundry about mock-submission => import design rules underlined
- request about DAC: modification of layout, need to assess amount of work (Hung)
- currently verification on-going at CERN
- PE finished, Xiaochao moving to time model of the pixel digital output and PE
- Jean starts using Voltus to estimate power dissipation on PE
- submission still planned for April
- Comments on Cliosoft-SOS use for MOSS-MOST, Fred
- discussion with Patrick Pangaud to understand some tech details
- one local PC will be dedicated to that, need some virtual machine setup with IPHC-IT service
- contribution from C4Pi: 2kEUR
- a SOS server will be set-up at IPHC with support from IT-service
- CE-65++, Andrei
- same status
- wait for results on current CE-65
- doing simulation on the DAQboard read-out chain to understand issues observed
- Clear interplay between resistances on boards, capacitances and phase-shift setup
- also reducing frequency should make things much more stable
- on top of under/over-shoot, pb of oscillation (that can be cured by changing resistances)
- Current conclusion
- carrier board should be OK from simulations
- proxy board is really the issue
- behaviour with frequency different in tests (effect visible) and simulations (effect no visible)
- TO DO
- Kimmo investigating the 10 MHz mode
- Andrei is continuing simulation
- need systematic measurements with changing phase-shift (Szymon, Serhyi ?)
- organize long discussion with experts!!
- nothing special from mock-up submission feedback
- wondering about pads: new metal stacks to be included, but CERN should take care of this
- so waiting if CERN will really move there on not
- not-clear what to do with top-layer
- same status
- NEXT MEETING, Thursday 3rd February, 10h30
