FIGURE 2. Traditional X-ray scattering experiment setup. Photo Credit: Argonne National Laboratory. In addition to the setup shown in Figure 2, time resolution at BioCARS is provided by precise synchronization of additional beam blocking equipment placed before the sample under test—two rotating disk choppers and a shutter [2]. The X-ray beam is intercepted by a watercooled heat load chopper wh...

Laser Cooled High-Power Fiber Amplifier

A theoretical model for laser cooled continuous-wave fiber amplifier is presented. The amplification process takes place in the Tm 3+ -doped core of the fluoride ZBLAN (ZrF4-BaF2LaF3-AlF3-NaF) glass fiber. The cooling process takes place in the Yb 3+ :ZBLAN fiber cladding. It is shown that for each value of the pump power and the amplified signal there is a distribution of the concentration of ...

Analysis of Operational Regimes of a High Power Water Load

Reflections, electric field and dissipated power of a 915 MHz water load produced by The Ferrite Company, Inc. are computed by QuickWave-3D for water temperatures from 5 to 60∞C. A simple empirical model generalizing experimental data is used for calculating the dielectric constant of fresh tap water at 915 MHz and for different temperatures. The computer model is verified by measurement of ref...

High Temperature, High Power RF Life Testing of GaN on SiC RF Power Transistors

As GaN power device technology matures and gains acceptance in the market place, suppliers who provide products using this promising technology must prove its reliability. This paper will provide an overview of the testing approaches used to establish failure rates and will provide a comparison of DC and RF based HTOL methods. The primary focus of this paper will be the high power RF HTOL test ...
