11:00am-11:10am- Charles Romero - GBT+MUSTANG-2 capabilities and outlook

11:15am-11:25am - David Frayer - GBT Capabilities and Performance at High Frequency

11:30am-11:40am - Tony Mroczkowski - Instrumentation for AtLAST

11:45am-11:55am - Asantha Cooray - Origins Space Telescope survey science program

12:00pm-12:30pm - Instrument discussion panel: Charles Romero, David Frayer, Tony Mroczkowski, Asantha Cooray, Simon Dicker

Guiding discussion questions:

• What is the maximum field of view and number of detectors that we can achieve with modest repurposing of the GBT?

• What are the CMB specs of AtLAST and can it realistically achieve CMB in HD science?

• How many years does it take for AtLAST to achieve 0.1uk-arcmin over 4000 sq deg, assuming 20% observing efficiency?  What NET and number of detectors does that assume?

• What wavelengths are the highest priority for the 1st generation AtLAST instrumentation?

• Would fewer spatial elements but better spectral resolution have any advantages? (e.g. mm-wave BAO and RSD, kSZ, & rSZ at the expense of CMB sensitivity)

• What is the main science from the Origins Space Telescope, and how can it complement CMB in HD?
