SLAC-2017:Sensors and Readout Parallel Session

Back to SLAC-2017 main page

Optical Coupling, Sensors

• System Engineering Context and Goals
  • Opening Statements
  • Interface Issues and System Engineering considaraitons

• Optical Coupling
  • 1-slide short presentation
    • Simons Observatory Detector Plans (Arnold): File:2017-02-28 SimonsObservatoryDetectorPlans Arnold.pdf
    • ANL: 3G experience and scaling to S4 — Clarence
    • NIST Development & Fab Summary (and assembly discussion point, if time) — Jay
    • LBNL/UCB hybrid commercial detector fabrication — Toki File:CMBS4 DetectorFabrication HybridCommercial.pdf
    • LEKIDs and MKIDs — Brad File:Bjohnson 2017 stanford cmb-s4 slide.pdf
  • Input/Output
    • 1 slide from Toki to motivate discussion: File:OpticalCouplingInputOutput.pdf
    • Interface with detector group: optical, readout, mechanical
    • Give acceptable range for these values, not just single value. It gives other teams (instrument and forecast) room to wiggle around and think through multiple scenarios without coming back to us each time they want to change something.
  • Jeff on systems engineering

- Presentation pushed to Wednesday (we'll try to cover this if we have time. My apologies if we can't cover it on Tuesday.)

• Horn Coupled Multichoric Detector Coupling Design

Readout

• • uMUX update (Jay)
  • On wafer muMUX (McMahon for Michigan and NIST)
  • SLAC RF electronics: File:20170228 slac electronics.pdf
  • Hf-DfMUX: Media:S4_hf_dfmux_readout-v2.pdf

Notes from session

Take notes here.

Action items/Next steps

• Agree on list of input and output for each sub-group
• Make table, then start filling in input and output for given technology. Input and output maybe in parametric form (for example beam FWHM vs pixel size, mapping speed vs receiver and sky temp)
• Start discussing throughput. Detector fabrication, assembly, test. Feed back cycle time
