Description

The ARES (Accelerator Research Experiment at SINBAD) is a conventional S-band linear RF accelerator allowing the production of low charge ultra-short electron bunches within a range of currently 0.01 pC to 250 pC. The R&D accelerator also hosts various experiments. Different types of charge monitors are installed along the 45m long machine: A new Faraday Cup design had been simulated and realized. Two Beam Charge Transfomers (Toroids) are installed. Both, Faraday Cup and Toroids are calibrated independently with laboratory setups. At the end of the accelerator a Bergoz Turbo-ICT (in vaccum) and an in-air ICT are installed. This presentation will give an overview of the measured linearity and the deviations found at the Toroid measurement.
