Argus: Software meeting at the GBT

Kiruthika and Sarah attended a software meeting at the Robert C. Byrd Green Bank Telescope (GBT), Green Bank, West Virginia  in August, 2013. This meeting was aimed at working out the software needs once Argus is fielded at the GBT, to enable astronomers to observe with the focal plane array.

140 GHz LNA Measurements Presented at IMS 2013

In collaboration with scientists at JPL and NGC, Patricia presented her recent measurements of three different InP 35 nm gate-length High Electron Mobility Transistor (HEMT) Low Noise Amplifiers (LNAs) at the 2013 International Microwave Symposium in Seattle, WA.  The measurements included a record low spot noise temperature for cryogenic HEMT LNAs: 46 K at 152 GHz.  The conference paper, “Low Noise Amplifiers for 140 GHz Wide-Band Cryogenic Receivers,” will be available online soon.  Abstracts can be found in the conference program.

Argus Preliminary/Critical Design Review

We had our preliminary and critical design reviews (PDR/CDR) for Argus at Stanford, CA on Apr 20-22, 2013. The goal of the PDR/CDR was to have end-to-end design review, and freeze interfaces between sub-assemblies, where possible. Argus is on a very tight schedule, with commissioning to start in Nov, 2014. So, we identified and addressed as many of the schedule risk items as possible at the meeting.

The Interstellar Medium in High Redshift Galaxies Comes of Age

An overview of the Argus focal plane array was presented as a poster at the NRAO workshop on “The Interstellar Medium in High Redshift Galaxies Comes of Age“. This workshop focussed on the study of molecular emission at high redshift. The poster is provided here. The short paper Argus that was published is provided here.
