Time-of-flight facility for the absolute measurement of the beam energy of a medium-energy cyclotron
Publikováno v:
Nuclear Instruments and Methods in Physics Research. 204:41-45
A method for measuring the energy of a medium-energy cyclotron is presented. It is based on a single detector which simultaneously detects gamma rays from two spatially separated targets. The method is absolute depending upon the cyclotron or local o

A Monte Carlo program is described that calculates the neutron intensity from the bombardment of thick beryllium targets with deuterons of energies from 14 to 40 MeV. Calculations give neutron intensities off the deuteron beam axis as well as as on-a

The growing use of internally deposited radionuclides in radioimmunotherapy has established the need for accurate information about the energy deposition by low-energy electrons at the cellular level. To the present time only theoretical calculations

Cross sections for neutron production from targets of 2 H, 6 Li, 7 Li, 9 Be, 12 C and 27 Al have been measured at 0° for incident proton energies of approximately 30, 40 and 50 MeV. For production of a monoenergetic neutron beam in this energy regio

The design and performance of a solenoidal type beta ray spectrometer is discussed. The uniform (1 in 104) magnetic field is measured and controlled by nuclear magnetic resonance of the proton. A mean take-off angle of 23.50 is employed with a scale

Calculations and experimental technique used in producing a uniform magnetic field with an end‐corrected solenoid are discussed. The field was trimmed to be uniform to 0.01% in an axial region comprising 63% of the solenoid at a maximum field stren

The neutron detection efficiency of a plastic scintillator 30.5 cm long and 12.7 cm in dia. has been measured for neutron energies from about 10–70 MeV. These were obtained by scattering a 193 MeV neutron beam from a liquid hydrogen target. A teles
