In-situ high voltage generation with Cockcroft-Walton multiplier for xenon gas time projection chamber
Shinichi Akiyama, Junya Hikida, Masashi Yoshida +17
We have newly developed a Cockcroft-Walton (CW) multiplier that can be used in a gas time projection chamber (TPC). A TPC requires a high voltage to form an electric field that dri…

High-pressure xenon gas time projection chamber with scalable design and its performance at around the Q value of Xe double-beta decay
Masashi Yoshida, Kazuhiro Nakamura, Shinichi Akiyama +18
We have been developing a high-pressure xenon gas time projection chamber (TPC) to search for neutrinoless double beta () decay of Xe. The unique feature of this TPC…
