Abstract

The invention relates to an automatic beam spot calibration and beam adjustment device for a nuclear track membrane production terminal. The device comprises two beam signal detection devices, a dataacquisition device, a control computer and a power supply, the two beam signal detection devices are arranged in a transmission channel of a beam pipeline and are used for detecting a visible light video image capable of representing the beam position and shape of a beam in the transmission channel; the data acquisition device is used for acquiring visible light video images; and the control computer is used for analyzing the beam spot position and shape of the beam in the acquired visible light video image, and controlling the power supply to adjust the beam spot position and shape accordingto the analysis result, so as to realize automatic beam spot calibration and beam adjustment of the nuclear track membrane production terminal. The device can be widely applied to the production of the nuclear track membrane.

Description

technical field [0001] The invention relates to an automatic beam spot adjustment device for nuclear pore membrane production terminal beam spot calibration, and relates to the technical fields of nuclear pore membrane irradiation production and fluorescent target monitoring. Background technique [0002] Nuclear pore membranes are the most precise microporous filtration membranes in the world. It is a porous plastic film with densely packed small holes, each of which has the same shape and size. The nuclear pore membrane has many specifications, the membrane thickness ranges from 5 microns to 60 microns, the pore diameter ranges from 0.2 microns to 15 microns, and the pore density ranges from 1-10 to the 9th power per square centimeter. [0003] Nuclear pore membranes are generally perforated by heavy ions provided by high-energy accelerators. Heavy ion perforation is the most critical part of the production process of nuclear pore membranes. Only a few countries in the w...
