AC Materials proposes development of a 4 micron Ho:BaY2F8 laser pumped by a Cr:LISAF laser in response to Air Force needs for an efficient pulsed source in the 3-5 micron region. Under the Phase I program lasing at 3.9 micron was demonstrated, with over 30mJ power per pulse. The Phase II effort will be optimization of this Ho laser. Crystal growth of Cr:LiSAF and Ho:BYF will be advanced to enable ...

The proposed Phase II program will optimize the design and manufacturing process of a compliant brush shroud casing. Recent tests at Wright Laboratories with staged brush seals have demonstrated significantly increased blade to shroud rub tolerance of acompliant casing. Phase I of the program is expected to demonstrate the feasibility of two innovative brush shroud designs with lower cost and we ...

Single event transient (SET) effects on combinational logic have not been widelystudied because they have been deemed less important than logic circuits untilthe advent of deep sub-micron technologies. These new circuits tend to be moresensitive to SET because of the higher operating speeds and higher clock rates,and the smaller transistors themselves are more sensitive to radiation.AET, Inc. is ...

The objective of this SBIR effort is to develop and demonstrate the technical feasibility of an improved ultra wideband antenna element technology suitable for both receive and transmit functions. The end goal is to significantly extend the currentstate-of-the-art in ultra wideband phased array and individual antenna technology, both from a performance as well as from a practical implementation s ...

The current antennas of choice for earth stations are parabolic reflector antennas such as those used for tracking telemetry and control (TT&C) for the AFSCN. These antennas are required to have horizon-to-horizon, full-hemispherical coverage and oftenseveral antennas are required at each remote tracking station site. A single active hemispherical phased array antenna composed of flat panel suba ...
