Development of a Low-beta BPM for MYRTE Project
Résumé
MYRTE (MYRRHA Research Transmutation Endeavour) performs research to support the development of the MYRRHA (Multi-Purpose Hybrid Research Reactor for High-Tech Applications) research facility, which aims to demonstrate the feasibility of high-level nuclear waste transmutation at industrial scale. MYRRHA Facility aims to accelerate 4mA proton beam up to 100 MeV. The accurate tuning of LINAC is essential for the operation of MYRRHA and requires measurement of the beam transverse position and shape , the phase of the beam with respect to the radiofrequency voltage with the help of Beam Position Monitor (BPM) system. MYRTE aims to qualify beam operation at 1.5MeV. Two BPMs were realized for MYRTE operation. This paper addresses the design, realization, and calibration of these two BPMs and their associated electronics. The characterization of the beam shape is performed by means of a test bench allowing a position mapping with a resolution of 0.02mm.
