Particle accelerator system for the production of standard neutron fields to replace existing Van de Graff accelerator

Description

A particle accelerator capable of accelerating protons and deuterons to any energy between 200 keV and 4 MeV. The system will produce a DC ion beam with a maximum beam current of at least 300 µA. The system will include ion source(s), accelerator, beamlines, switching magnet, ion optics/monitoring and control systems. The system will interface with building utilities and safety systems. The accelerator will be used primarily for producing neutron standards, but also opens up options for charged particle irradiations for materials analysis and nuclear physics experiments. Lot 1: The accelerator system will be capable of delivering accelerated ion beams to neutron producing targets (targets not included in procurement). The system will include: • 2 multicusp ions sources to produce protons, deuterons and helium ions • Pulser/buncher system to produce pulses approximately 2 ns wide at frequencies up to 4 MHz • 2 MV Tandetron accelerator to accelerate protons and deuterons from 200 keV to 4 MeV and helium ions up to 8 MeV • Switching/analysing magnet • 2 beamlines (approx. 14 m and 7 m long) with associated ion optics (electrostatic quadrupoles) and monitoring (faraday cups and profile monitors) • Computer control system and software The ion sources, pulser/buncher, accelerator and switching/analysing magnet will fit in the existing accelerator room (approx. 11 x 8.5 m) and the beamlines will extend into the neighbouring experimental area. The procurement will include transportation, on-site acceptance testing, training of personnel and equipment warranty.
