Energy reduction device, energy reduction method, electronic equipment and computer readable storage medium

Abstract

The invention relates to the technical field of energy reduction, and particularly discloses an energy reduction device, an energy reduction method, electronic equipment and a computer readable storage medium. The energy reduction device comprises a first energy reduction piece and a second energy reduction piece which are coaxially arranged, the thickness of the first energy reduction piece is in a spiral change trend in the circumferential direction of the first energy reduction piece, and the thickness of the second energy reduction piece is in a spiral change trend in the circumferential direction of the second energy reduction piece. When at least one of the first energy reduction piece and the second energy reduction piece rotates along the shaft, the superposition thickness of the first energy reduction piece and the second energy reduction piece in the axial direction is in a monotonous change trend. When the first energy reduction sheet and / or the second energy reduction sheet rotate along the shaft, the combined and superposed thickness of the first energy reduction piece and the second energy reduction piece in the axial direction is continuously changed and is in a monotonous change trend, so that when the energy reduction device is arranged on an incident path of charged particles, the energy of the charged particles can be continuously reduced through the energy reduction device, and the continuous adjustment effect of charged particle energy is realized.

Description

technical field

[0001] The present invention relates to the field of energy reduction technology, in particular to an energy reduction device, an energy reduction method, electronic equipment and a computer-readable storage medium. Background technique

[0002] In general, high LET (Linear Energy Transfer, linear energy transfer) ion irradiation experiments need to be carried out on a heavy ion cyclotron, the type and initial energy of the heavy ions obtained are fixed, and the initial LET value of heavy ions during the test is It is also a definite value. When the LET value of the ion needs to be changed, it is usually necessary to reduce the energy of the heavy ion. At present, the commonly used method is to use energy-degrading sheets of different materials and thicknesses to reduce the energy of heavy ions, thereby changing the LET value of heavy ions after passing through the energy-degrading sheets. Generally, the higher the atomic number, the better the energy reduct...
