Simulations of Surface X-ray Diffraction from a Monolayer 4He Film Adsorbed on Graphite
Atsuki Kumashita, Hiroo Tajiri, Akira Yamaguchi +7
We carried out simulations of crystal truncation rod (CTR) scatterings, i.e., one of the surface X-ray diffraction techniques with atomic resolution, from a monolayer He film adsor…
Construction of Continuous Magnetic Cooling Apparatus with Zinc Soldered PrNi Nuclear Stages
Shohei Takimoto, Ryo Toda, Satoshi Murakawa +1
We report design details of the whole assembly of a compact and continuous nuclear demagnetization refrigerator (CNDR) with two PrNi nuclear stages, which can keep temperature…
A Simple Experimental Setup for Simultaneous Superfluid-response and Heat-capacity Measurements for Helium in Confined Geometries
Jun Usami, Ryo Toda, Sachiko Nakamura +2
Torsional oscillator (TO) is an experimental technique which is widely used to investigate superfluid responses in helium systems confined in porous materials or adsorbed on substr…
Structural Study of Adsorbed Helium Films: New Approach with Synchrotron Radiation X-rays
Akira Yamaguchi, Hiroo Tajiri, Atsuki Kumashita +7
A few atomic layers of helium adsorbed on graphite have been attracting much attention as one of the ideal quantum systems in two dimension. Although previous reports on neutron di…
Superconducting Niobium Calorimeter for Studies of Adsorbed Helium Monolayers
Jun Usami, Koki Tokeshi, Tomohiro Matsui +1
We developed a calorimeter with a vacuum container made of superconducting niobium (Nb) to study monolayers of helium adsorbed on graphite which are prototypical two-dimensional qu…
Negative resistance state in superconducting NbSe induced by surface acoustic waves
Masahiko Yokoi, Satoshi Fujiwara, Tomoya Kawamura +5
We report a negative resistance, namely, a voltage drop along the opposite direction of a current flow, in the superconducting gap of NbSe thin films under the irradiation of s…
