New Evidence for Geomagnetically Trapped Anomalous Cosmic Rays
We report new observations of _> 15 MeV/nuc trapped heavy ions with Z_> 2, made on the polar-orbiting SAMPEX spacecraft in late 1992 and early 1993. A trapped population that includes He, N, O, and Ne is found to be located at L -2. We conclude that the observed N, O, and Ne ions are "anomalous" cosmic rays, trapped by the mechanism proposed by Blake and Friesen. While it is not expected that t...
متن کاملMeasurement of the Neutron Lifetime by Counting Trapped Protons
We measured the neutron decay lifetime by counting in-beam neutron decay recoil protons trapped in a quasi-Penning trap. The absolute neutron beam fluence was measured by capture in a thin (6)LiF foil detector with known efficiency. The combination of these measurements gives the neutron lifetime: τ n = (886.8 ± 1.2 ± 3.2) s, where the first (second) uncertainty is statistical (systematic) in n...
متن کاملEnergy Spectrum of Fast Neutrons Produced by 130 MeV Protons in Water
In proton radiation therapy nuclear reactions of highenergy protons hitting beam line components (e.g. collimators or other beam shaping devices) lead to the production of secondary neutrons which may result in significant neutron dose equivalent values (typically of the order of mSv per treatment Gy), depending on the treatment techniques [1]. For scanning devices the neutron dose contribution...
متن کاملBroad energy spectrum of laser-accelerated protons for spallation-related physics.
A beam of MeV protons, accelerated by ultraintense laser-pulse interactions with a thin target foil, is used to investigate nuclear reactions of interest for spallation physics. The laser-generated proton beam is shown (protons were measured) to have a broad energy distribution, which closely resembles the expected energy spectrum of evaporative protons (below 50 MeV) produced in GeV-proton-ind...
متن کاملThe energy spectrum of cosmic ray protons in the local interstellar medium
A number of analyses of cosmic gamma ray data from the Compton Gamma Ray Observatory have found that the energy spectra are flatter than would have been expected if the spectra of protons in the producing regions were of the same shape as that measured at earth. Although it is true that technical artifacts could be responsible a variety of arguments to be advanced here make us conclude that the...
