By: Marcel, Jan, Hendrik
Participants: Jan, Yi (ATLAS), Hendrik, Doris, Claus K., Daniel, Guenter E. (CMS), Karsten H., Inge, Pradeep (FE), Trixi (FS-DS), Ingrid, Marcel (ATLAS), Ties (FLC/MT), Felix (FLC/AIDA2020)
ALPIDE is not the ultimate candidate, but brings along improvements (besides spatial res.) in comparison to Mimosa, is cheap and available
Daniel: Other candidates: DEPFET (BelleII), 50x50 pitch, pulse height information, but availability poor, slow production and slow r/o, costly
Someone: Moench, 25 x 25, but with ASIC, and not designed for tracking
Karsten: Ongoing dev. of CMOS-DEPFET for DSSC until 2019, camera for XFEL.
Daniel: HV-CMOS, Mu3e → MuPix8, AMS-foundry refuses new orders from science. In principle a HV+HR-CMOS could be thin and "fast enough"
Ties: FPCCD dev. at KEK, 8x8 pitch, ...
Marcel: We need 2x2 cm area, and at least 100 chips being available
Hendrik: Monolithic SOI (e.g. Cracow, 30 x 30, below 2 um resolution, not thinned yet)
Marcel: Use this as a tool to kick-start development
Trixi: Will this work with Mimosa Life-time
Ingrid: Two-Step approach: First Alpide, start in parallel with novel development; Jan: Modular framework provides smooth transition for users
Daniel: AlpidePRIME, remove event buffers needed for LHC operation (trigger latency), and re-synthesize on smaller real estate
Ties: Market survey of candidates
Trixi: Find out the Delta: What can we have? – What do we want?; and if possible requirements for the far future 10 years
Trixi: In Photon Science: Identify key users and then look if you can also please others
→ core requirements and nice-to-have list → for convincing the management/directorate
Ties: Fundamentally, we should do it! Go for a new system:
Felix: Timing is the hot topic
Jan: An extended beam tool for wider community (e.g. calorimeters)
Other arguments: DESY sources, export options (successful for EUDET) e.g. GeV energies, infrastructure support/management
Attract, maybe problematic as also European framework as AIDA
DSF: Money for exploration and reasons why not funding it from core? We can get a post-doc for two years ← check
DDL Helmholtz: from 2022 10 million invest → later, R-Weg e.g.
ERC: ambitious in 2 ways
Matter Forum: EUDAQ2 for Proposal (This fall) 1 Person (PostDoc)
DESY II TBF is unique
Hendrik: New beam lines will need new tools → Beam line needs
R-Weg is happening: 10^10 electrons in 2ns every 80-160ms.
Jan: What about EU-Praxia beam tools?
Marcel: DESY IV is coming, maybe with slow extraction
