Long-Running-Time (T=0.45 K) Germanium Bolometer for Far Infrared Spectroscopy
この論文をさがす
説明
<jats:p> A long-running-time (<jats:italic>T</jats:italic>=0.45 K) germanium bolometer which has a compact charcoal adsorption pump with a novel <jats:sup>3</jats:sup>He gas condenser has been constructed. The refrigerator provides continuous cooling of the bolometer element at 0.45 K for 24-hour measurements of spectra in the range 2 to 40 cm<jats:sup>-1</jats:sup>. Utilizing this bolometer system, transmission spectroscopy has been carried out successively, maintaining the temperature of the sample below 40 K and that of the bolometer element below 1.5 K without a thermal cycle. This experimental setup is essential for obtaining a reproducible spectrum of MEM(TCNQ)<jats:sub>2</jats:sub>. Thus, each resultant spectrum has good reproducibility even after one-week-long experiments. </jats:p>
