Charged-particle magnetic-quadrupole spectrometer for neutron induced reactions

PDF Version Also Available for Download.

Description

A spectrometer has been developed for measuring the charged particle production cross sections and spectra in neutron-induced reactions. The spectrometer consists of a magnetic quadrupole doublet which focuses the charged particles onto a silicon surface barrier detector telescope which is 2 meters or more from the irradiated sample. Collimators, shielding, and the large source-to- detector distance reduce the background enough to use the spectrometer with a 14- MeV neutron source producing 4 . 10$sup 12$ n/s. The spectrometer has been used in investigations of proton, deuteron, and alpha particle production by 14-MeV neutrons incident on various materials. Protons with energies ... continued below

A spectrometer has been developed for measuring the charged particle production cross sections and spectra in neutron-induced reactions. The spectrometer consists of a magnetic quadrupole doublet which focuses the charged particles onto a silicon surface barrier detector telescope which is 2 meters or more from the irradiated sample. Collimators, shielding, and the large source-to- detector distance reduce the background enough to use the spectrometer with a 14- MeV neutron source producing 4 . 10$sup 12$ n/s. The spectrometer has been used in investigations of proton, deuteron, and alpha particle production by 14-MeV neutrons incident on various materials. Protons with energies as low as 1.1 MeV have been measured. The good resolution of the detectors has also made possible an improved measurement of the neutron- neutron scattering length from the 0$sup 0$ proton spectrum from deuteron breakup by 14-MeV neutrons.
