Detector array demonstrates novel microwave readout

Over the years, SRON has developed increasingly sensitive Transition Edge Sensors (TES) for space missions such as SPICA and Athena. One of those TES detector arrays, developed as backup X-ray microcalorimeters for Athena, has now played a vital role to demonstrate a new readout technology developed at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. This technology is called low-noise microwave SQUIDs multiplexed readout. The research results are published i...
