Description

The electro-static septum (ESS) comprise the cathode plate and thin ribbons which are stretched to the yoke in J-PARC. Two electric septa are used upstream of septum magnets. Fluorinert FC40 are chosen as an insulation liquid for the feedthrough and cable connection device. Since the viscosity is small, it is easy to handle, additionally, in case that the feedthrough is broken by the spark, it would reduce the risk of contamination of the vacuum. The demerit of fluorinert is that the degradation product such as hydrogen fluoride (HF) is created under the high radiation environment. The circulation system was introduced in order to eliminate HF. We report the circulation system of fluorinert and the result of the filtration. (author)
