The SPT-3G+ receiver design
H. Athreya, Z. Ahmed, J. E. Austermann +71
We present the thermo-mechanical design of the cryostat and camera optics for SPT-3G+, a new receiver being developed for the South Pole Telescope (SPT). The receiver consists of 1…
Higher Order Nyquist Zone Sampling with RFSoC Data Converters for Astronomical and High Energy Physics Readout Systems
Chao Liu, Zeeshan Ahmed, Shawn W. Henderson +2
From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases signif…
Evaluating Direct RF Sampling Performance for RFSoC-based Radio-frequency Astronomy Receivers
Chao Liu, Larry Ruckman, Ryan Herbst
As the maximum RF input and output frequencies of the integrated data converters in RFSoC increase, it becomes practical to digitize and synthesize RF signals in the majority of C…
A Microwave SQUID Multiplexer Optimized for Bolometric Applications
B. Dober, Z. Ahmed, K. Arnold +27
A microwave SQUID multiplexer (MUX) has been optimized for coupling to large arrays of superconducting transition-edge sensor (TES) bolometers. We present the scalable cryogenic…
Antarctic Radio Frequency Albedo and Implications for Cosmic Ray Reconstruction
D. Z. Besson, J. Stockham, M. Sullivan +42
From an elevation of ~38 km, the balloon-borne ANtarctic Impulsive Transient Antenna (ANITA) is designed to detect the up-coming radio frequency (RF) signal resulting from a sub-su…
TARGET: A multi-channel digitizer chip for very-high-energy gamma-ray telescopes
K. Bechtol, S. Funk, A. Okumura +5
The next-generation very-high-energy (VHE) gamma-ray observatory, the Cherenkov Telescope Array, will feature dozens of imaging atmospheric Cherenkov telescopes (IACTs), each with…
IceCube's In-Ice Radio Extension: Status and Results
H. Landsman, E. Cheng, E. Kulcyk +5
In 2006-2010, several Radio Frequency (RF) detectors and calibration equipment were deployed as part of the IceCube array at depths between 5 to 1400 meters in preparation for a fu…
