摘要
Purpose and background As the magneto-resistor technology is developed,applying it to beam instrumentation for the accelerator becomes possible.In this paper,a new principle beam current sensor based on TMR linear sensor is introduced.Methods Feasibility research by simulation and calculation has been done,a study of the critical component for the whole system has been carried out,and all these are presented in this paper.Results and conclusions Laboratory test results include the nonlinear error,and resolution analysis is introduced.Specific work plan for the next step of the improvement and upgrade is also referred to.
