Method and apparatus for measurement of physical properties of matter under simultaneous control of radio frequency and variable temperatures

摘要

An apparatus allows a sample mounted within a temperature controlled radome system to be tested. The apparatus maintains the sample under controlled temperatures and allows radiation from a radiation source to expose the sample to broadband electromagnetic radiation of varying power, frequency and angle of incidence.

主权项

1. An apparatus comprising:
a radiation source configured to direct radiation to a sample under test; a refrigeration system configured to provide a controlled temperature to the sample under test, wherein the refrigeration system includes:
a cold source, anda cryostat operably coupled to the cold source, the cryostat being configured to maintain temperature control of the sample and to keep the sample under at least one of vacuum and controlled gas atmosphere; and a radome system where the sample under test is placed, wherein the radome system is configured to:
allow electromagnetic radiation from the radiation source to be incident upon the sample,maintain the sample under the controlled temperature while the sample is exposed to the electromagnetic radiation, andbe substantially transparent to the electromagnetic radiation directed to the sample.
