Estimation of Newtonian noise from KAGRA cooling system
Rishabh Bajpai, Takayuki Tomaru, Toshikazu Suzuki +3
KAGRA is the first km-scale gravitational wave detector to be constructed underground and employ cryogenics to cool down its test masses. While the underground location provides a…
A laser interferometer accelerometer for vibration sensitive cryogenic experiments
Rishabh Bajpai, Takayuki Tomaru, Kazuhiro Yamamoto +5
Monitoring motion originating from ultra low-temperature cooling systems like cryocoolers is important for vibration sensitive cryogenic experiments like KAGRA. Since no commercial…
Vibration Analysis of KAGRA Cryostat at Cryogenic Temperature
Rishabh Bajpai, Takayuki Tomaru, Nobuhiro Kimura +4
KAGRA uses cryogenics to cool its sapphire test masses down to 20 K to reduce the thermal noise. However, cryocooler vibration and structural resonances of the cryostat couple to t…
Development and application of a He Neutron Spin Filter at J-PARC
T. Okudaira, T. Oku, T. Ino +22
We are developing a neutron polarizer with polarized He gas, referred to as a He spin filter, based on the Spin Exchange Optical Pumping (SEOP) for polarized neutron scatte…
