Purpose and backgroundAs 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.MethodsFeasibility 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 conclusionsLaboratory 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.
