A control and data acquisition system for a large volume superheated droplet detector

Large-volume room-temperature superheated droplet detectors are being constructed for measuring very weakly interacting radiation fields, such as those produced by Cold Dark Matter particles (CDM particles, or Weakly Interacting Massive Particles: WIMPS), and various versions of Control and Data Acquisition systems (CDAQ) have been developed for such detectors. Large active mass droplet detectors are modular, their sensitivity is strongly temperature dependent and their operation requires measurements and control functions which are unique to this particular detection medium. We present the CDAQ systems developed for the PICASSO project for different levels of operation. Other types of applications of such detectors are also being investigated and appear promising.
