Numerical simulation of relativistic electron energy spectrum measurement based on graphite slices calorimeter

Graphite slices calorimeter is a traditional device for the energy diagnosis of the relativistic electron beams. The measurement of the electron energy spectrum is simulated through a series of numerical experiments, and a spectrum skipping method is investigated. With an MCNP experiment model, transfer functions between the input electron energy and the deposited energy are established for different electron deposited energy distributions. In addition, a method for solving the transfer functions is proposed, and its reliability is investigated by introducing human disturbances.
