The capture efficiency of high field flux concentrator

A flux concentrator body cut leads to nonsymmetrical distortion of a transverse magnetic field. The results of positron tracking in distorted magnetic field and positron capture efficiency are presented in this paper for incident electron bunch energy of 6.2 GeV and tungsten positron production target with length of 5 rad

Project of deuteron accelerator based neutron source for rib production

The project of a high-intense neutron source for the SPES project in LNL, Legnaro, Italy [1] is developed. The source is based on the rotating carbon target. The target is bombarded by the deuteron beam with energy 20 MeV, diameter 1 cm, average power 100 kW. The target is cooled by its thermal radiation, and its temperature can reach 1800ºC. It is shown that high density graphite can be used as a material for neutron production. The source can produce up to 10¹⁴ neutrons per second with energy within few MeV - few dozens MeV range, its lifetime is around few thousand hours

Project of a fast neutron target based on a 10 MeV 300 kW proton accelerator

Project of targets for high intense neutron source is proposed. The source is based on a proton continuous accelerator with the 10 MeV particle energy and up to 300 kW mean beam power. Problems of fabrication of these targets are discussed. Hot solid state and liquid target designs are considered. Maximum admissible target parameters are presented. Advantages and disadvantages of various types of target for neutron production are discussed
