Performance evaluation of GYGAG crystals for neutrinoless double beta decay search
Hibiki Hayasaki, Keishi Hosokawa, Koichi Ichimura +6
Neutrinoless double beta decay (0) is a crucial for confirming neutrinos' Majorana characteristics. Previous searches for 0 decay of Gd using GSO crystals was con…
Performance evaluation of Luxium Solutions BCF-XL wavelength-shifting fibers
Tatsuki Yamazumi, Yota Endo, Shoma Kodama +4
We evaluate the performance of single-clad wavelength-shifting fibers newly developed by Luxium Solutions, BCF-92XL, BCF-9929AXL, and BCF-9995XL and compare them with the multi-cla…
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…
Performance of new Kuraray wavelength-shifting fibers with short decay time
Shoma Kodama, Hokuto Kobayashi, Wataru Okinaga +3
We measure the decay time and the attenuation length of newly developed wavelength-shifting fibers, YS series from Kuraray, which have fast response. Using a 405 nm laser, the deca…
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…
