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 ...

Fuels in high altitude and latitude aircraft (e.g., the U-2) must have freezing point temperatures well below -60 ¿C, and must maintain flow to similar temperatures (e.g., viscosity of ~ 6 cSt). JPTS, a high purity kerosene based fuel has the requiredproperties, but costs ~ 3 times more than standard jet fuels, such as JP-8 (military grade) or Jet A (commercial). The need for JPTS also presents ...

Crested multi-layer tunnel barriers have been proposed, which offer a revolutionary solution to overcome density to speed trade-offs characteristic of present data storage technologies. Practical implementation of the proposed technology will involve useof thin film materials which are readily manufacturable and CMOS-compatible. A critical need exists for experimental verification of the theoret ...

During aircraft turbine engine operation, augmentor (afterburner) operation is often associated with combustion instabilities (oscillations) that can be potentially detrimental to the turbine engine if the resonant amplitude levels are excessive.Oscillation in the frequency range of 50-100 Hz is commonly called

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 ...

Radar represents a strategically critical military application where microwave vacuum electronic (MVE) apmplifiers are relied upon for their supperior power handling characteristics. MVE amplifiers provdi esuperior performance capabilities forapplications requiring high power density. The objective of thsi ersearch project is to develop a high power klystron apmplifier with substantially reduced ...

Interpretation of observed phenomena from time series is often complicated by measured quantities being only indirect indicators of a system's state. Information about a system may be filtered by properties of the transmission medium, or by the manner inwhich the information is collected. Multiple time series, though possibly concurrent, may be acquired differently, with different averaging or del ...
