Aims: The emergence of the superheated liquid technique in the direct search for astroparticle dark matter has had a significant impact on the international dark matter search effort. It differs from other techniques in recording the sound associated with the transition of a metastable liquid to its gas phase stimulated by incident particle energy loss.
Place and Duration of Study: Department of Nuclear Engineering and
Sciences, Lisbon, Portugal between June 2024 and November 2024.
Methodology: Among its advantages is a tuneable 10-10
level insensitivity to the majority of traditional detector backgrounds which
plague more conventional dark matter search detectors, and discrimination of
the remainder. The insensitivity is not trivial, translating to a reduced data
record, and simplified, more efficient analyses of the results.
Results: The straightforwardness of the detectors, their
instrumentation and data analysis, and their capacity for target variations
have provided at a minimum a relatively inexpensive and competitive search
approach.
Conclusion: A description of the prominent dark matter search
aspects common to the four superheated liquid efforts (SIMPLE, COUPP, PICASSO,
PICO), with some comparison made with those of the other more traditional
techniques in use.
