This cryogenic helium wind tunnel has been designed to study high
Reynolds number turbulent flow. It can be utilized to explore both grid
generated turbulence and turbulent flow around objects such as spheres or
airfoils. The properties of low temperature helium gas and liquid allow us to
achieve the highest levels of turbulence in a facility many times smaller than
a conventional wind tunnel facility. |

| Closed cycle helium 3 cryostat maintains 0.3K temperature for 36
hours before recycling. Used for Radio Astronomy, Upper Atmospheric
spectro-photometry and laboratory spectroscopy.

This view of the SAFIRE Detector Mount Prototypes shows two mounts for
unsressed Ge:Ga photoconductors and two for stressed arranged to show a
portion of the full focal plane array for two spectral channels. A full focal
plane consists of 48 such units arranged in three subassemblies. The screws
for applying the uniaxial force to the crystal are seen on the left two units.
The approximately 1 mm size germanium detector crystal mounts in the 2 mm dia
cavity located in the center of the upward facing facit. The left hole and
split hole are used for attaching the individual units to the focal plane
superstrustructure. The small access panel covers a cavity for mounting the
cold feedback resistor. The material is a special high strength steel with a
gold coating.

The Instrument made to measure the Earth's radiance through cirrus
clouds. This instrument has been flown on a T-39 and a Lear25C. Scheduled
for flight in Fall 2000 on the Proteus aircraft.
