Abstract
Driven by research and development of advanced photon detectors--which require temperatures below 100mK-- there is considerable research into new ADR designs and techniques. In particular the continuous ADR (CADR)has many advantages over other technique to achieve ultra-low temperature and there is considerable commercial potential. We propose to design control system (including instrumentation) for a CADR. Phase II will start with a review of the circuit model and software model developed in PhaseI. We will build a complete prototype insturment and control software. They will be developed and tested interanlly and with an on-site evaluation at contracting site. We will also study system improvments in particular XML web server control and open loop control for the upper stages. All studies and testing results will be used to develop the final integrated control system.
