Gigabit Ethernet Daisy-Chain on FPGA for COMET Read-out Electronics
Eitaro Hamada, Yuki Fujii, Youichi Igarashi +7
The COMET experiment at J-PARC aims to search for the neutrinoless transition of a muon to an electron. We have developed the readout electronics board called ROESTI for the COMET…
Data acquisition system in Run-0a for the J-PARC E16 experiment
Tomonori Takahashi, Kazuya Aoki, Sakiko Ashikaga +26
J-PARC E16 is an experiment to examine the origin of hadron mass through a systematic measurement of spectral changes of vector mesons in nuclei. The measurement of pa…
An FPGA-based Trigger System with Online Track Recognition in COMET Phase-I
Yu Nakazawa, Yuki Fujii, Masahiro Ikeno +7
An FPGA-based online trigger system has been developed for the COMET Phase-I experiment. This experiment searches for muon-to-electron conversion, which has never been observed yet…
Performance of the Unified Readout System of Belle II
Mikihiko Nakao, Ryosuke Itoh, Satoru Yamada +24
The Belle II experiment at the SuperKEKB collider at KEK, Tsukuba, Japan has successfully started taking data with the full detector in March 2019. Belle II is a luminosity frontie…
Study of scintillation light collection, production and propagation in a 4 tonne dual-phase LArTPC
B. Aimard, L. Aizawa, C. Alt +160
The m demonstrator is a dual phase liquid argon time projection chamber that has recorded cosmic rays events in 2017 at CERN. The light signal in these de…
Front-end-Electronics for the SiPM-readout gaseous TPC for neutrinoless double beta decay search
K. Z. Nakamura, S. Ban, A. K. Ichikawa +7
We have developed a dedicated front-end-electronics board for a high-pressure xenon gas time projection chamber for a neutrinoless double-beta decay search. The ionization signal i…
Performance evaluation of a silicon strip detector for positrons/electrons from a pulsed a muon beam
T. Aoyagi, Y. Honda, H. Ikeda +26
A high-intensity pulsed muon beam is becoming available at the at the Japan Proton Accelerator Research Complex (J-PARC). Many experiments to study fundamental physics using this h…
J-PARC Neutrino Beamline Upgrade Technical Design Report
K. Abe, H. Aihara, A. Ajmi +381
In this document, technical details of the upgrade plan of the J-PARC neutrino beamline for the extension of the T2K experiment are described. T2K has proposed to accumulate data c…
A New Approach for Measuring the Muon Anomalous Magnetic Moment and Electric Dipole Moment
M. Abe, S. Bae, G. Beer +93
This paper introduces a new approach to measure the muon magnetic moment anomaly , and the muon electric dipole moment (EDM) at the J-PARC muon facility. The g…
Trigger Merging Module for the J-PARC E16 Experiment
M. Ichikawa, T. N. Takahashi, K. Aoki +13
An experiment to measure an invariant mass of ϕ mesons in nuclear medium is planned as the J-PARC E16 experiment. A trigger merging module (TRG-MRG) has been developed to detect le…
