Abstract

An innovative design of 16-channel front-end electronics for ionization chamber in monitoring proton beam profile has been developed to feature simplicity, low cost, durability, and reliability without compromising its performances. All the parts are available off the shelf. The front-end electronics board is powered by USB connection, through which the data are transferred to the host computer for storage and further online analysis. The system has been studied with Geant4 MC and tested with both electron and proton beams.
