screen grid ionization chamber spectrometer

Product Introduction

screen grid ionization chamber is an electron collection pulse ionization chamber commonly used to measure the energy of alpha particles or fission fragments. It includes a tablet and an additional pole (gate) to reduce the influence of heavy ions. The additional electrode is at an intermediate potential. On the one hand, the screen grid ionization chamber has the time characteristics of the electron collection block to improve the counting rate capacity, and at the same time eliminates the dependence of the output pulse amplitude of other similar ionization chambers on the initial ionization position, which can be used for particle energy measurement.

The use of screen ionization chamber to measure the nuclear reaction data of neutron-induced outgoing charged particles has some outstanding advantages, such as high particle detection efficiency (close to 100), the solid angle of detection is close to 4 & pi;, and the particle angle distribution, energy spectrum and double differential cross section data can be obtained at the same time. When the pressure of the working gas is changed, it can adapt to the measurement of different energy and different kinds of charged particles and has the particle resolution ability. These advantages make it an important means of measuring charged particles. The voltage of each pole is selected so that the electron collection satisfies the saturation condition and the gate non-trapping condition.

Screen grid ionization chamber spectrometer electronics system Shipingshan ionization chamber detector supporting electronics, its main function is to convert the ray signal measured by the screen grid ionization chamber into the user's visual map, through the map analysis to obtain the required information.
