In situ baking method for degassing of a kicker magnet in

In this study, the authors propose a new in situ degassing method by which only kicker magnets in the accelerator beam line are baked out without raising the temperature of the vacuum chamber to prevent unwanted thermal expansion of the chamber. By simply installing the heater and thermal radiation shield plates between the kicker magnet and the chamber wall, most of the heat flux from the

As a result, the graphite heater was selected for in-situ bake-out of the kickers in the RCS beam line. Using the method, the each material of kicker magnet was heated up above 100 with keeping the temperature rise of the vacuum chamber below 30 .

IN-SITU SAMPLE PREPARATION One of the principal challenges in high precision isotopic analysis using mass spectrometry is identifying and eliminating interfering species. For example, in small samples analyzed by Secondary Ion Mass Spectrometry (SIMS), 238U may complex with hydrogen to form 238UH, which appears at mass 239 and causes an interference with 239Pu.

But, this new measuring method, B-OTDR method, is just in development. There is very few case of applying this measuring method to actual structures. This paper describes a new measuring method using optical fiber strain sensors (B-OTDR method) applying to an actual concrete underground tunnel which was expected to deform by new shaft work near this tunnel.

Thus, we developed the in-situ degassing method for the ferrite cores. This is achieved by directing the heat from the heat source to the kicker magnet and not to the chamber wall. With the test stand we succeeded to flow almost all the heat toward the kicker magnet and to bake out the ferrite cores about 150C, maintaining the temperature of the chamber wall less than 50C.
