Receiver Systems for Radio Astronomy
Why temperature and noise have more in common than a unit
Christoph Brem
M.Sc., Dipl. El. Ing. FH, HF Systems Engineer, Skyguide ltd.
While not often in the scientific spotlight, radio astronomy is an
important contributor to our understanding of the Universe. It is a
fast evolving field and modern radio telescopes have high demands
on best possible receiver performance.
The talk will look at receiver systems used for radio astronomy with
a particular focus on cryogenically cooled receivers. To understand
the use of these systems in the context of their application, the
presentation will also cover some basic principles of radio astronomy and the different types of radio telescopes currently in use
and under construction in Australia.
Christoph Brem studied Electrical Engineering
at the HSR in Rapperswil, where his last year
of study focused on RF Engineering. He also
holds a Master’s Degree in Astronomy from the
Center for Astrophysics and Supercomputing at
Swinburne University of Technology, based in
Melbourne, Australia. From 2007 until 2016 he
worked for CSIRO, Australia’s national science
agency, holding different positions in the field of
radio astronomy instrumentation and observatory operations.
During the Antarctic summer 2010/2011 he also worked at the
South Pole Telescope, which is operated by the University of
Chicago. For his work while deployed to Antarctica he was awarded
the Antarctica Service Medal from the United States National
Science Foundation (NSF).
Since April 2016 Christoph Brem is back in Switzerland working for
Skyguide as Project Manager and Systems Engineer AIR COM.
