78276S Sources of high-peak-power millimeter-wave radiation are needed for development and testing of components and structures for a future multi-TeV electron-positron collider. A pulse compressor must generate the 200 MW pulses needed to develop structures for the CERN two-beam accelerator, or for a similar high-gradient millimeter-wave accelerator. This project will develop high-power switch ...

78728 A stand-alone 200 MW radio frequency (RF) test station is needed for developing accelerator structures and components for a future high-gradient multi-TeV collider, such as CLIC. In addition, a high-power RF window will be needed to isolate the test station from a structure element under test. This project will develop such a window for use in the frequency range 30-35 GHz, along with a h ...

78413SThe international high-energy physics community has decided to develop superconducting radio frequency (RF) technolgy to be the basis for the International Linear Collider, a 0.5 - 1.0 TeV electron-positron collider that is intended to complement the Large Hadron Collider. The 1.3 GHz RF power needed to drive this accelerator is now planned to be supplied by 600-1200, 10-MW peak power multi ...

78070S The realization of a future multi-TeV electron-positron collider rests, among other factors, upon the development of structures that can sustain high acceleration gradients. This project will develop a rectangular waveguide containing planar dielectric slabs as a high-gradient accelerator structure. This Ka-band, dielectric-loaded rectangular accelerator structure will have high shunt i ...

The overall goal of this program (through Phase III) is to develop an analyzer that can be integrated into International Space Station (ISS) toilets to measure key chemicals in urine. The analyzer will employ a novel metal-doped sol-gel material to both separate these key chemicals from urine and provide surface-enhanced Raman spectra to identify and quantify these chemicals. The Phase I program ...

The overall goal of this program (through Phase III) is to develop an analyzer to measure chemical signatures of life in extraterrestrial settings. The analyzer will employ a lab-on-a-chip to extract biochemical signatures from soil or water samples and surface-enhanced Raman spectroscopy (SERS) to detect and identify the signatures. The Phase I program successfully employed a metal-doped sol-ge ...

This Small Business Innovation Research (SBIR) Phase I research project will develop Raman spectroscopy as a novel analytical tool to monitor and control chemistry in small-scale reactors (microliter to milliliter). Small scale reactors are being developed to: (1) create new chemical reaction processes; (2) increase yields of existing processes; and, (3) replace scaling-up by numbering-up producti ...

The overall goal of this proposed program (through Phase III) is to provide the EPA with a chemical sensor thatn can be multiplerxed into water distributon systems to provide early warning of poisoned water supples. This will be accomplished by developing surface-enhanced Raman (SER) sensors than can be integrated into water supply systems and coupled to a central Paman analyzer via fiber optics. ...

A highly efficient optoelectronic (OE) interface is an essential element for satellite data interfaces. The emphasis is on high speed, low power and radiation-hardening. Key to the performance is the transponder subsystem consisting of the photoreceiver (detector , TIA and decision circuit), the clock and data recovery (CDR) circuit consisting of phase detector and voltage controlled oscillator (V ...

Phased arrays are critical for surveillance and tracking. Current TR modules use numerous MMIC chips, ferrite circulators and phase shifters and quasi-optical true-time-delay (TTD). A major power requirement is distribution and synchronization of the T/R function across multiple RF interfaces. Large scale integration could address the problem of interconnecting boards with GHZ RF outputs but is c ...
