The IFMIF-EVEDA accelerator will be a 9 MeV, 125 mA CW deuteron accelerator which aims to validate the technology that will be used in the future IFMIF accelerator. Non-interceptive Beam Position Monitors pickups (BPMs) will be installed to measure the transverse beam position in the vacuum chamber in order to correct the dipolar and tilt errors. Depending on the location, the response of the BPMs must be optimized for a beam with an energy range from 5 up to 9 MeV and a current between 0.1 and 125 mA. Apart from the broadening of the electromagnetic field due to the low-beta beam, specific issues are affecting some of the BPMs: tiny space in the transport line between the RFQ and cryomodule (MEBT), cryogenic temperature inside the cryomodule, phase and energy measurement in the diagnostics plate, and debunching and big vacuum pipe aperture at the end of the high energy beam transport line. For this reason different types of BPMs are being designed for each location (MEBT, cryomodule, Diagnostics Plate and High Energy Beam Tranport Line). In this contribution, the design of each BPM will be presented, focusing on the electromagnetic response for high-current low-beta beams. |
