27th November 2013 - The best laid plans...

Posted: 04 Feb 2014

Angela and Mike took me (Luke – their new Dphil student) to HartRAO in November where we met up with Charles for an intense two weeks of commissioning.

For the first half of our visit things went to plan. We got rid of some high system temperature features at around 5.3 GHz which turned out to be caused by radiation leaking through little thermal breaks inside the cryostat. We stopped this leakage with a bit of cutting and sticking of loaded silicone absorber - I never would have guessed that my first trip to a telescope as a graduate student would require so much arts and crafts!
