Bubble Chamber Experiments on Charmed Particle Lifetimes
The three current bubble chamber experiments on charmed particle lifetimes are compared. Their most recently released results are discussed. Although single charmed decay vertices have been seen in bubble chambers before, this discussion will cover the three current experiments. Two are at CERN and the third at SLAC. All use bubble chambers with relatively high resolution photographic technique...
متن کاملAcoustic Sensor Design for Dark Matter Bubble Chamber Detectors
Dark matter bubble chamber detectors use piezoelectric sensors in order to detect and discriminate the acoustic signals emitted by the bubbles grown within the superheated fluid from a nuclear recoil produced by a particle interaction. These sensors are attached to the outside walls of the vessel containing the fluid. The acoustic discrimination depends strongly on the properties of the sensor ...
متن کاملPerformance of a Rapid Cycling Hydrogen Bubble Chamber
A small hydrogen bubble chamber consisting of a convoluted bellows and driven by a loudspeaker-like coil expansion system was developed and tested to cycling rates of 90 Hz. (Submitted to Nucl. Instr . and Methods. ) * Work performed under the auspices of the U.S. Atomic Energy Commission. Present theory and research 192 indicate that under fairly conventional operating conditions in a hydrogen...
متن کاملRe-analysis of Some Bubble Chamber Data on Nn Annihilation
A re-analysis of some pp and pn data, at rest and in flight, obtained in bubble chamber experiments, is presented. The (ππ) and (KSKS) final states for the channels (2ππ) and (KSKSπ) are investigated. Evidence for a narrow meson resonance structure, cautiously suggested as f0(1500), is given. In the (π π) invariant mass distribution from pn annihilations in flight, using the method of differenc...
متن کاملSpin-dependent WIMP limits from a bubble chamber.
Bubble chambers were the dominant technology used for particle detection in accelerator experiments for several decades, eventually falling into disuse with the advent of other techniques. We report here on a new application for these devices. We operated an ultraclean, room-temperature bubble chamber containing 1.5 kilograms of superheated CF3I, a target maximally sensitive to spin-dependent a...
