The helium standard of Japan, referred to as HESJ, is an inter-laboratory
standard for the 3He/4He ratio. While the ratio of 3He and 4He of the HESJ was
previously determined by a relative comparison to atmospheric helium, the
absolute value of th...

"Neutron Optics and Physics (NOP/ BL05)" at MLF in J-PARC is a beamline for
studies of fundamental physics. The beamline is divided into three branches so
that different experiments can be performed in parallel. These beam branches
are being used ...

The neutron lifetime is one of the basic parameters in the weak interaction,
and is used for predicting the light element abundance in the early universe.
Our group developed a new setup to measure the lifetime with the goal precision
of 0.1% at t...

In special tests, the active layers of the CALICE Digital Hadron Calorimeter
prototype, the DHCAL, were exposed to low energy particle beams, without being
interleaved by absorber plates. The thickness of each layer corresponded
approximately to 0...

We present a study of showers initiated by electrons, pions, kaons, and
protons with momenta from 15 GeV to 150 GeV in the highly granular CALICE
scintillator-tungsten analogue hadronic calorimeter. The data were recorded at
the CERN Super Proton ...
