Clover would have been an experiment to measure the
History
The Clover Project was meant to consist of two independent telescopes, one operating at 95
receivers would have been large format focal plane arrays of either 100 or 200 bolometric detectors.[2]
The aim of the experiment was to measure the
gravitational waves
in the universe so long as the ratio of scalar perturbations (caused by density fluctuations in the early universe) to the tensor perturbations caused by gravitational waves was greater than .[2]
It was hoped that the telescope would have spent around 2 years observing a total of around 1,000 degrees of sky, made up of several patches of sky where polarized foregrounds (synchrotron and thermal dust emission) are at a minimum.[2]
Clover was canceled in March 2009 as STFC were unable to provide the requested additional funds of 2.55 million pounds to finish the project.[3]
