Medium Background Facility (VNIIOFI)<br />
for VTBB and fixed-point BB comparison<br />
<strong>The</strong> Medium Background<br />
Facility (MBF) was<br />
constructed to provide<br />
the absolute radiometric<br />
calibration <strong>of</strong> blackbody<br />
sources <strong>of</strong> thermal<br />
radiation, to compare<br />
radiometric scales with<br />
predictions for the<br />
measured temperatures,<br />
and to serve as a highly<br />
stable transfer standard<br />
for calibration <strong>of</strong><br />
blackbody sources under<br />
the medium vacuum<br />
conditions (10 - 4 Torr)<br />
and medium background<br />
environment (liquid<br />
nitrogen cooled shroud)<br />
