Development of a current measurement system for 4πγ ionization chamber
A current measurement system named ICMS-TIA (Ionization Current Measurement System based on Transimpedance Amplifier) for rapid and accurate measurement of the ionization current of 4πγ ionization chamber is developed based on an improved high-value resistance I-V conversion method with range switching function. The effective measurement range of the ICMS-TIA is from 50 fA to 50 μA and the response time of the system is less than 2.8 s. The test shows that the deviation of the current measurement above 1 pA is less than 0.41%, and the uncertainty over a range of current levels is given. In the linearity tests, the maximum deviation is 1.15 %. These tests indicate that this system can be used for current measurement of 4πγ ionization chamber.
期刊介绍：
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
