Second gadolinium loading to Super-Kamiokande
K. Abe, C. Bronner, Y. Hayato +246
The first loading of gadolinium (Gd) into Super-Kamiokande in 2020 was successful, and the neutron capture efficiency on Gd reached 50\%. To further increase the Gd neutron capture…
Prototype study of and tolerant Resistive Plate Chamber with Diamond-Like Carbon electrodes
Kei Ieki, Weiyuan Li, Atsuhiko Ochi +5
A novel Resistive Plate Chamber (RPC) was designed with Diamond-Like Carbon (DLC) electrodes and performance studies were carried out for 384 gap configuration with…
Study on degradation of VUV-sensitivity of MPPC for liquid xenon scintillation detector by radiation damage in MEG II experiment
K. Ieki, T. Iwamoto, S. Kobayashi +6
In the MEG II experiment, the liquid xenon gamma-ray detector uses Multi-Pixel Photon Counters (MPPC) which are sensitive to vacuum ultraviolet (VUV) light under a high-intensity m…
Development of ultra-low mass and high-rate capable RPC based on Diamond-Like Carbon electrodes for MEG II experiment
Kensuke Yamamoto, Sei Ban, Kei Ieki +5
A new type of resistive plate chamber with thin-film electrodes based on diamond-like carbon is under development for background identification in the MEG II experiment. Installed…
Development of high-rate capable and ultra-low mass Resistive Plate Chamber with Diamond-Like Carbon
Atsushi Oya, Kei Ieki, Atsuhiko Ochi +3
A new type of resistive plate chamber (RPC) is under development using thin-film resistive electrodes based on diamond-like carbon (DLC). Planned to be put on the path of high-inte…
A photogrammetric method for target monitoring inside the MEG II detector
G. Cavoto, G. Chiarello, M. Hildebrandt +7
An automatic target monitoring method based on photographs taken by a CMOS photo-camera has been developed for the MEG II detector. The technique could be adapted for other fixed-t…
