Radio Astronomy

With the Coolstar range of Gifford McMahon (GM ) Cryocoolers, Oxford Cryosystems is able to provide low-cost and effective coolers for the Radio Astronomy community. 

The Coolstar range comprises some of the most versatile and compact Cryocoolers available today, offering fast cooling, long service intervals and easy OEM integration. Our development team is always keen to work with companies and facilities looking for a tailored solution to a problem, meaning we can offer a dynamic approach to collaborations with external parties.

As a result of this approach, our Coolstar Cryocoolers have been selected for a  number of different Radio Astronomy applications, including the prestigious Square Kilometre Array (SKA), an international US$1.9 billion project to build the world’s largest radio telescope. So far, Oxford Cryosystems have been involved in the design stage, and have already supplied  hundreds of coldheads to Meerkat, the precursor to the SKA.

Over the next 10 years, thousands of antennae will be built in South Africa with, potentially, up to 6 of our cryocoolers on each dish.

Single stage coldhead
Single stage coldheads

The Coolstar single stage coldheads comprise the 0/12 and 0/40 models, respectively delivery cooling powers of 12 and 40 W at 77 K. 

K450 helium compressors

The K450 compressor delivers compressed helium to the Coolstar coldhead and controls coldhead motor speed for optimised performance.

Two stage coldheads

The Coolstar two stage coldheads comprise the 2/9 and 6/30 models, both delivering base temperatures as low as 10 K.
