摘要：

Two types of microwave filters, metallic powder fitters and a tilter using a resistive coaxial cable, were tested. Attenuation of the metallic powder filters using copper or stainless steel (SUS304L) was measured at 300 K, 77 K, and 4.2 K, and it was found that SUS304L powder of nominal 30 mu m grain size gives best result as the microwave filter for single electron tunneling (SET) experiments, Attenuation of a coaxial filter, or Thermocoax with SMA connectors attached at both ends is larger at low temperatures than that at room temperatures, and the temperature dependence of the attenuation does not agree with Zorin's model, The filter arrangement in our cryostat designed for SET experiments, is also reported.
