Abstract

The invention relates to a tritium target apparatus. The tritium target apparatus comprises a target main body and an accelerator interface; the target main body comprises a target sheet; and the target sheet comprises a substrate and a diamond layer arranged on the substrate and with high thermal conductivity performance, wherein when a tritium ion beam passes through the accelerator interface to shoot and bombard the target sheet, the released heat energy passes through the diamond layer to be absorbed and diffused and then to be transferred to the substrate. By adoption of the mode, the temperature of the target sheet can be controlled effectively, runaway and loss of tritium atoms in working can be avoided, apparatus performance degradation can be avoided, and the apparatus can be protected effectively; and in addition, enlargement of the diameter and improvement of the rotating speed of the target sheet are not needed, and the mechanical strength and the like of the apparatus can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of ion beam bombardment devices, in particular to a tritium target device. Background technique [0002] The deuterium-tritium fusion neutron generator uses a high-speed deuterium ion beam to bombard a tritium target to undergo a deuterium-tritium fusion reaction, forming helium atoms and releasing neutrons. Tritium targets are important components in neutron generators. It is generally based on copper or its alloys with high thermal conductivity, and its thickness is generally several mm (millimeters). Its surface is coated with a titanium film adsorbed with tritium, and its thickness is generally several μm (micrometers). The high-speed deuterium ion beam reacts with the tritium atoms in the titanium film to produce neutrons. The heat generated during the reaction is deposited in the target, and then taken away by the cooling fluid on the back of the target. Since the heat flux density during ...
