Following a first successful demonstration of the use of MPPCs in scintillator-based
calorimeters, the CALICE collaboration has developed over the last years a concept
scalable to large collider detectors with millions of channels, thanks to embedded
read-out electronics layers including surface-mounted MPPCs. A prototype with
22000 channels has been constructed and was tested in hadrons...
International Linear Collider (ILC) is a project of a future electron–positron collider and one of its goals is precise measurements of the Higgs particle.
We are developing Scintillator Electromagnetic Calorimeter (ScECAL) with SiPM as one of candidates of electromagnetic calorimeter for ILC.
ScECAL consists of 2mm x 5mm x 45mm scintillator strips and SiPMs.
We have fabricated some types...
The KOTO experiment, conducted at J-PARC (Ibaraki Japan), is set to observe
the rare decay $K_L\rightarrow \pi^0 \nu \bar{\nu}$. The branching ratio is heavily suppressed
in the Standard model (SM) and the
experimental observation may reveal hints
from physics beyond the SM.
The observed signature of $K_L\rightarrow \pi^0 \nu \bar{\nu}$ is two $\gamma$'s
produced from a $\pi^0$ and
no...
Plastic scintillator detectors are extensively used in particle physics experiments for decades. A large-scale detector is typically arranged as an array of staggered long bars which provide a fast trigger signal and/or particle identification via time-of-flight measurement. Scintillation light is collected by photosensors coupled to the both ends of every bar. In this talk we present our...
We plan to equip about 60,000 MPPCs to build novel plastic scintillator detector for T2K near detector upgrade. Current goal of the T2K experiment is to measure CP violation phase in the neutrino sector, by measuring neutrino appearance in the long-baseline neutrino experiment. The upgrade of T2K near detector (ND280) aims to suppress systematic error to obtain better sensitivity for the...
We have developed HypTPC consists of TPC and the trigger hodoscope for the J-PARC E42/45 hadron experiments. The TPC Hodoscope has large scintillators of 80 x 7 x 1 cm to cover the TPC. Especially, to detect photons generated in a large area of a scintillator, a multiple MPPC signal readout is developed.
Generally, a method of applying a voltage to a Multi-MPPC is a parallel connection and...
