A 230 GHz heterodyne receiver array for the IRAM 30Â m telescope
We describe the technical concept, properties, and performance of HERA
(HEterodyne Receiver Array) at the IRAMÂ 30Â m telescope. HERA is a
multibeam, waveguide SIS receiver that greatly improves mapping
speed in various observing modes and also provides possibilities
for new high-sensitivity observing of small sources. Future
extensions with a second polarization module will permit
spectro-polarimetry. We present some examples of astronomical maps
with HERA.
