PAF (FLAG) Wideband Feeds Best on single dish High Cost Single dish application = smaller funding community Excellent Tsys/h Excellent survey speed “stuck” with cryo approach? Science support Trade Space Warm L-band PAF (depend on better processing-JPL) HI Pulsar (need wider BWs) Star formation (K-PAF) Wideband Feeds Science support Trade Space Promising emerging technology Has application to interferometers (ngVLA, FAST) = larger international funding community Spillover and matched waveguides and LNAs a challenge RFI a potential issue…but mitigated by improved ADCs and RFI algorithms Pulsar (need wider BWs, esp. for timing) Astrochemistry Single pixel vs. multi-pixel

Feed horn arrays/ FPA (ARGUS) Science support Trade Space More easily scalable than PAFs Can be scaled up without large R&D investments (LO distribution possible exception). Cradle of life Pulsars Implementation/sensitivity Bolometer FPA (MUSTANG) Science support Trade Space Possible to scale up number of pixels without large investment Lower temperature operation best way forward, but requires R&D. Can use kinetic inductance parametric up convertors (KPUPs) to increase multiplexing technology Possible leverage of ongoing work on NbTiN superconductors and TKIPs (see below). Cluster science Star formation (dust) 5K operation

Traveling-wave Kinetic Inductance Parametric Amplifiers (TKIPs) DSP and Large Arrays Science support Trade Space Take advantage of Moore’s law/better ADCs and the need to periodically replace digital back ends Could enable 103 to 106 elements up to 100 GHz BW Traveling-wave Kinetic Inductance Parametric Amplifiers (TKIPs) Science support Trade Space Near quantum-limited performance over an octave of BW Operates a milli-Kelvin now – possibility to leverage MUSTANG’s cryostat Researching 5K operation with a gain >15 dB over a bandwidth of 55-175 GHz Leverages wide BW feed horns Pulsars Supports WB spectrometer Astrochemistry

Radar Transmission/Reception Science support Trade Space RFI and DSP Increase requirement (smallsats, automotive radar…). Leverages RFI work on other telescopes (ngVLA?) and commercial DSP and ADC developments SETI Trade Space Radar Transmission/Reception Science support Possibility on monostatic operation ? Planetary mapping/probing Planetary protection
