Abstract

The invention relates to the technical field of proton adsorbed dose research, and specifically relates to a high-energy proton beam density distribution testing device. The device comprises a vacuum cavity, a Faraday cup, a multi-dimensional moving platform, a shielding box and a static electrometer, wherein the Faraday cup is fixed in the vacuum cavity through the multi-dimensional moving platform, and is enabled to be opposite to a proton beam in the vacuum cavity. The Faraday cup is connected with the input end of the static electrometer in the shielding box, and a grounding end of the static electrometer and the Faraday cup are connected with a side wall of the vacuum cavity through grounding lines. A motor controller in the shielding box is connected with the multi-dimensional moving platform, and can control the multi-dimensional moving platform to move. The device provided by the invention can test the density distribution of the high-energy proton beam in the vacuum cavity, and can achieve the comprehensive assessment of a charge environment in an electronic sample room. The impact on the device from the external interference is small, and the device can effectively detect the density distribution of the high-energy proton beam.

Description

technical field [0001] The invention belongs to the technical field of proton absorbed dose research, and in particular relates to a high-energy proton beam current density distribution testing device. Background technique [0002] Proton is an important bombardment particle used to produce reactions in nuclear physics and particle physics experiments, and it is also the main component of cosmic rays. The composition of ionizing radiation in space is very different from that on the ground, and the radiation intensity is also higher than that on the ground. In extraterrestrial space, ionizing radiation is an important environmental factor that must be encountered and unavoidable in space activities. [0003] For electronic systems applied to satellites or space vehicles, in the natural space radiation environment, the performance is often reduced or malfunctioned due to space radiation, and even ultimately leads to catastrophic consequences for satellites or space vehicles. ...
