A fabrication of low-power distribution systems for muon g-2/EDM experiment at J-PARC

초록

A special DC-to-DC converter is designed to supply low-power to the detector system of the J-PARC g - 2/EDM experiment, which aims to measure the anomaly of the muon magnetic dipole moment, a(mu) = (g - 2)/2. The important requirement of the DC-to-DC converter is that the stray magnetic field from the converter should be less than 30 mu T to reach the experimental sensitivity of 450 ppb. The DC-to-DC converter contains one buck converter and three regulators, featured with a customary designed air-core inductor. The detailed design and test results for the voltage stability, stray magnetic field, and heat dissipation in vacuum are reported.
