SOLEIL is a third generation synchrotron light source located near Paris. Due to the high performance required for SOLEIL’s diagnostics, a special production procedure was tailored. During the production of 131 Beam Position Monitors (BPM) more than 500 feedthroughs were inspected; all of them passed strict tests at different stages of the production: Leak test (< 10-10 mbar l/s), Dimensional control (Displacement <0.050 mm), Vacuum test (Specific Outgassing < 10-12 mbar l/s cm2, Residual Gas Analysis) and Electrical test (Capacitance measure ~8pF, Insulation >50 MΩ, Impedance <0.1 Ω). All the established procedures and tests have been performed in a tight partnership that was more than a simple contractual framework, in which an intensive collaboration led to a knowledge transfer between SOLEIL and Rial Vacuum. The result has been a high percentage of success (few feedthroughs over 500 were replaced) during preliminary tests and a deeper knowledge of “BPM problem solving”; in this article are presented different test procedures to obtain high quality and high performance BPMs.
