Title: Development of bubble chambers with enhanced stability and sensitivity to low-energy nuclear recoils

Abstract

The viability of using a Bubble Chamber for rare event searches and in particular for the detection of dark matter particle candidates is considered. Techniques leading to the deactivation of inhomogeneous nucleation centers and subsequent enhanced stability in such a detector are described. Results from prototype trials indicate that sensitivity to low-energy nuclear recoils like those expected from Weakly Interacting Massive Particles can be obtained in conditions of near total insensitivity to minimum ionizing backgrounds. An understanding of the response of superheated heavy refrigerants to these recoils is demonstrated within the context of existing theoretical models. We comment on the prospects for the detection of supersymmetric dark matter particles with a large CF{sub 3}I chamber.

  • Bubble nucleation in moderately superheated liquids can be triggered by nuclear recoils from WIMPs. This phenomenon is the basis for superheated droplet detectors. The droplet technique is currently limited by insensitivity to spin-independent interactions, due to lack of heavy elements in the usual target liquids, and sensitivity to contamination of the gel by alpha emitters. As an alternative, we have developed a new type of homogeneous bubble chamber, which can contain heavy liquids, including CF3Br, CF3I, and C3F8. Detectors of this type may be scalable to large size at modest cost and could have very low backgrounds. We discuss resultsmore » obtained with a 12 ml prototype and plans for a 1 liter chamber.« less

  • Work done on bubble chamber data processing methods in the past two years is reviewed. It includes improvements to the now standard methods, development of new measuring devices, and progress on completely automatic systems. Most projects for automatic processing of spark chamber pictures take the most recent bubble chamber analysis techniques as their starting point, but several methods to determine spark positions without the use of film are reviewed in relation to their possible use in an automatic data analysis system. Development of data processing methods for counter experiments has shown two main features since 1980: (1) construction and usemore » of a variety of digital data- handling systems, and (2) use of digital computers on-line to control data flow, to do a certain amount of processing during an experiment, and to carry out checks on the operation of the equipment.
