Description
Summary:The development of the next generation of accelerators for charged particle radiotherapy aims to reduce dimensions and operational complexity of the machines by engineering pulsed beams accelerators. The drawback is the increased difficulty to monitor the beam delivery. Within each pulse, instantaneous currents larger by two to three orders of magnitude than present applications are expected, which would saturate the readout of the monitor chambers. In this paper, we report of a simple method to increase by almost two orders of magnitude the current range of an Application Specific Integrated Circuit chip previously developed by our group to read out monitor ionization chambers.
