Ultrasonic Attenuation in Solid Helium
A great deal of information about the motion of dislocations in solid helium has been obtained from ultrasonic and interna1 friction measurements. A brief review is given and representative data for 3 ~ e are presented, showing dislocation resonance and damping as well as pinning effects.
متن کاملBubble 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 کاملKinetics of helium bubble formation in nuclear materials
The formation and growth of helium bubbles due to self-irradiation in plutonium has been modelled by a discrete kinetic equations for the number densities of bubbles having k atoms. Analysis of these equations shows that the bubble size distribution function can be approximated by a composite of: (i) the solution of partial differential equations describing the continuum limit of the theory but...
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...
