Group for Advanced Receiver Development
(GARD) |
Group for Advanced Receiver Development (GARD) is an instrumentation group of Onsala Space Observatory (OSO) and has two locations: at Chalmers University Campus in Gothenburg city, and at OSO. GARD is located in the house of Chalmers Microtecnology Centre (MC2). The Onsala Space Observatory is situated about 30 miles south from Gothenburg, and is the Swedish National Facility for Radio Astronomy. The Onsala Space Observatory is part of the Department of Radio and Space Science, Chalmers University of Technology, (CTH).

GARD Projects:
Atacama Pathfinder EXperiment (APEX)
(Joint Project by European Southern Observatory, Max Plank Institute for Radio Astronomy, Bonn and Onsala Space Observatory).
Atacama Large Millimeter Array (ALMA) Band 5
ALMA Band 5 is European Commission FP6 funded infrastructure project. The project aims developing components, design and built a prototype receiver cartridge to comply with specifications of ALMA Band 5. After that, six ALMA Band 5 receiver cartridges should be built. More information on ALMA could be found at the official project web-page http://almaobservatory.org/ ,
Current status of the project: PDR passed in March 2008, prototype cartridge is ready during Spring 2009. Extensive PDR documentation to the ALMA Band 5 Project could be found on ALMA documentation server. For more details please visit dedicated ALMA Band 5 Project page.
