# Development of a facility for research of charged particle emission induced by fast neutron reactions

• A facility has been constructed for research of charged particle emission
induced by fast neutron reactions ((n, x) reaction) based on the white
neutron source and the quasi-monoenergetic neutron source which will be
provided by the upgrade of the HI-13 Tandem Accelerator at China Institute
of Atomic Energy (CIAE).

The facility mainly consists of a cylindrical vacuum chamber with the diameter of 100 cm and the height of 50 cm, a target changer with 5 targetframes and eight ΔE-ΔE-E telescopes. Each telescope consists of two silicon detectors and a CsI crystal. Eight telescopes were mounted with 20°angle intervals; they can cover the detection angle from 20 to 160 degrees. ΔE-ΔE-E Techniques were used to obtain good particle identification (PID) for protons, deuterons, tritons, 3He and α particles over an energy range from a few MeV up to 100 MeV. All operations inside the vacuum chamber, i.e., changing the target sample, calibration with an alpha source, or rotation of the telescope table, can be made without breaking the vacuum.

Detailed description of the reaction chamber and the telescopes will be given in this report. The test results and the application of the facility in the future are also presented.

## Development of a facility for research of charged particle emission induced by fast neutron reactions

###### Corresponding author: LAN Chang-Lin,

Abstract:

A facility has been constructed for research of charged particle emission
induced by fast neutron reactions ((n, x) reaction) based on the white
neutron source and the quasi-monoenergetic neutron source which will be
provided by the upgrade of the HI-13 Tandem Accelerator at China Institute
of Atomic Energy (CIAE).

The facility mainly consists of a cylindrical vacuum chamber with the diameter of 100 cm and the height of 50 cm, a target changer with 5 targetframes and eight ΔE-ΔE-E telescopes. Each telescope consists of two silicon detectors and a CsI crystal. Eight telescopes were mounted with 20°angle intervals; they can cover the detection angle from 20 to 160 degrees. ΔE-ΔE-E Techniques were used to obtain good particle identification (PID) for protons, deuterons, tritons, 3He and α particles over an energy range from a few MeV up to 100 MeV. All operations inside the vacuum chamber, i.e., changing the target sample, calibration with an alpha source, or rotation of the telescope table, can be made without breaking the vacuum.

Detailed description of the reaction chamber and the telescopes will be given in this report. The test results and the application of the facility in the future are also presented.
