Conduction Effect of Thermal Radiation in a Metal Shield Pipe in a Cryostat for a Cryogenic Interferometric Gravitational Wave Detector
Takayuki Tomaru, Masao Tokunari, Kazuaki Kuroda +13
A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational…
Pulse tube cryocooler with self-cancellation of cold stage vibration
T. Suzuki, T. Tomaru, T. Haruyama +5
We experimentally demonstrated a new method for reducing the vibration of the cold stage of a cryocooler. Comparing the RMS amplitude with the case of no phase shift of the driving…
Cryogenic measurement of the optical absorption coefficient in sapphire crystals at 1.064(micro)m for the Large-scale Cryogenic Gravitational wave Telescope
Takayuki Tomaru, Takashi Uchiyama, Daisuke Tatsumi +6
We have applied laser calorimetry to the measurement of optical absorption in mono-crystalline sapphire at cryogenic temperatures. Sapphire is a promising candidate for the mirror…
