Abstract

Using a Perovskite crystal, a thermal detector has been designed for measurements of proton beam currents. For a given energy, the detector has a linear response with current intensity and an inverse response with chopping frequency. Measurements up to 50 nA (4.5 MeV H ⁺) were carried out using a cyclotron, and a calibration curve is presented. The detector may be used over a wide range of energies, has a low cost, and is simple to construct. In addition, it can be used inside or outside vacuum, and it does not require an external bias field
