Facilities at TvU
TvU currently occupies 3,000 square feet of office and laboratory space with a wide variety of
sophisticated experimental research and development equipment. TvU has invested its company profit
to fund development projects and to acquire a variety of sophisticated furnace, mechanical, optical,
electronic, and vacuum equipment, as well as fabrication, testing and support equipment. An optics
lab centers on a single sapphire fiber imaging calibration station. A vacuum processing lab centers
on a general purpose high vacuum station. A cryogenics lab centers on a Koch Helium Liquefier and
Janis Supertran Liquid Helium Cryostat with optical access. Air and vacuum furnaces (to above 2200°C)
are used for material processing experiments, and transparent furnaces and associated hardware permit
total optical access to small pieces undergoing heat treatment at temperatures up 1200°C.
