Abstract:

An electrostatic accelerating column was designed and fabricated by Lanzhou University for an intense DT/ D-D neutron generator. In order to achieve a neutron yield of 5.0 ×1012 n/s, a deuteron beam of 30 mA, accelerated to 400 kV, and transported in the electrostatic accelerating column smoothly are required. One particle-in-cell code BEAMPATH was used to simulate the beam transport, and the IONB1.0 code was used to simulate the intense beam envelopes. Emittance growths due to space charge effect and spherical aberration were analyzed. The simulation results show that the accelerating column can transport deuteron beam of 30mA smoothly and the requirement for the neutron generator is satisfied.
