ZDependence of Positive Pion Production by 340-Mev Protons

Coherent Pion Production by Neutrinos

I concentrate in this article on the reaction coherent pion production by neutrinos incident on nuclei. A special effort is made in order to describe the approximations entering the calculation. I conclude that the reaction is well understood and with appropriate data for hadronic reactions it can be computed for low and high neutrino energies. Because of shortage of space I omitted the resonan...

Production of 25 MeV Protons in CO2 Laser-Plasma Interactions in a Gas Jet

At the Neptune Laboratory at UCLA, we have developed a high-power CO2 MOPA laser system which produces world record, multi-terawatt 10μm pulses. The CO2 laser pulses consist of a train of 3ps pulses separated by 18ps, each with a peak power of up to 4TW and a total pulse train energy of ∼100J. These relativistic laser pulses are used for Laser Driven Ion Acceleration in a H2 gas jet operated ar...

Tracking Study of 200 MeV Protons within a PMMA Phantom

This paper describes an experiment that determined the position, and its associated uncertainty, of a proton at three different depths inside of a polymethyl-methacrylate (PMMA) absorber. These observed positions prove the fact that one can predict the most likely path (MLP) of a proton moving through a uniform medium, as long as the displacement and angle of that proton are known at the absorb...

Irradiation of silicon particle detectors with MeV-protons

Silicon particle detectors are used in several applications and will clearly require better hardness against particle radiation in the future large scale experiments than can be provided today. To achieve this goal, more irradiation studies with defect generating bombarding particles are needed. Protons can be considered as important bombarding species, although neutrons and electrons are perha...
