Abstract

The invention discloses a hard X-ray framing camera and a hard X-ray detection method thereof. The problem that in the prior art, two-dimensional imaging with time resolution capability cannot be carried out on hard X-rays with the energy section range of tens of keV to hundreds of keV is solved. The framing camera comprises a multi-channel hard X-ray detection cathode, a micro-channel plate, a fluorescent screen, a CCD, a pinhole array plate, an electrical control system, a cathode Au micro-strip, a conductive thin layer and a micro-channel plate Au micro-strip. The detection method mainly includes the steps that a target emits hard X-ray pulses to pass through the pinhole array plate, the multi-channel hard X-ray detection cathode, the micro-channel plate and the fluorescent screen, andfinally imaging is conducted on the CCD. The camera is simple in structure, scientific and reasonable in design and convenient to use, and two-dimensional imaging with the time resolution capability can be effectively carried out on the hard X-rays with the energy section range of tens of keV to hundreds of keV.

Description

technical field [0001] The invention relates to a hard X-ray framing camera and a method for detecting hard X-rays. Background technique [0002] X-ray framing camera is a two-dimensional image measurement device with time-resolving capability, which is widely used in the diagnosis of almost all ultrafast phenomena involving X-rays, such as: synchrotron radiation, inertial confinement fusion, Z-pinch plasma, linear Optical measurements of accelerators, etc., covering biomedicine, nuclear physics, plasma physics, strong field physics, etc. [0003] However, the current X-ray framing camera uses Au or CsI as the cathode material, and the response range to X-rays is less than 25keV. It cannot respond to hard X-rays with an energy range of tens of keV to hundreds of keV. However, in some cases, such as inertial confinement fusion physics research, X-rays in this energy range have time-resolved two-dimensional Imaging is very necessary. In response to this situation, we design...
