Write up:
- 1-page, one to two figures, bibtex for citation
- intro of technology
- survey current status
- R&D for S4
We should also add (suggestion from Jeff)
- we should put the OMT design into feed section since it is a limit on the achievable bandwidth of the horn coupled systems
- we should discuss dielectric materials somewhere (eg silicon oxide vs silicon nitride vs single crystal silicon) perhaps in RF tricks.
Meeting 03: 2016-06-16
- Deliverable: White paper by next S-4 meeting in September (6 more meetings to go)
- .tex file at github
- git clone https://github.com/CMB-S4/Memos.git
- Main .tex detector_rf.tex
- Outsource writing tasks to experts (our task is to bring back .tex, .png, .bib)
- Generic goal:
- Keep doors open - no down selection
- Survey of current technology and development
- Summarize necessary development for CMB-S4
- Collect references
- Scope/topics to address
- Total bandwidth per feed
- Broadband RF technology
- Feed
- RF circuit
- Mapping speed
- Diffraction
- Cold stop and telescope temperature
- Loss in optics (AR and lens material) and RF circuit line (choice of dielectric for ex)
- Broadband RF technology
- Resolving Power
- Need from foreground subtraction group
- Just point to their write up
- Atmospheric window
- Hardware requirement
- Finite area on silicon wafer
- Increase number of readout channels
- Need from foreground subtraction group
- Should we add/subtract scope from this group?
- Total bandwidth per feed
- Assign writing task
- Hardware
- Broadband RF technology (1.0 page)
- Hardware requirement on resolving power (1.0 page)
- Background Material
- Mapping speed (1.0 page)
- Atmosphere (0.5 page)
- Foreground (0.5 page)
- Hardware
- Meeting Note
- Participants: toki, clarence, mike, akito, bryan, jeff
- we have additional detector systematics group (mike sent out lists of group)
- what is trade off between total bandwidth
- zeesh is leading readout group - discuss if combining detector (TES/MKID) into readout makes sense
- trade off between too many / broader participation to be inclusive
- contact XXX if you want to get involved
- TES/MKID for readout group cause delay? - probably not
- include Mike N. to readout group
- send note to whole community - pass by john c. - send out note to whole s4 group
- we are missing group to put whole thing together
- how about 2-stage approach. we collect current state of technology for now. then optimize/tie together later
- optimize/tie together to come after science book
- re-name systematics group to systematics and system over view?
- keeping systematics group shows that we are thinking about systematics and its mitigation
- no body knows about what systamtics to worry about at CMB-S4 level
- separate group's writing
- how to select co-leader?
- cryogenic receivers group does not exist (ask brad to lead?)
- systematics group can suggest what simulation/study is necessary
- describe different experiment's approach to systematics
- summarize literature on analysis technique
- summarize experiment's approach
- Action Item
- jeff to put together preamble and send out with mike n's list of groups
- jeff to ask zeesh to agree on adding tes/mkid to readout
- natural point
- sarah for horn
- sinuous lenslet
- roger phase-array
- mapping speed/atm/foreground (background material)
- next meeting in 2 weeks. maybe we'll get more participants. Toki's organize meeting (doodle, call invitation what not)
