40268 November 6, 1996 Alameda Applied Sciences Corporation Induction linear accelerators that produce energetic heavy ion beams are a prime candidate for power-producing fusion reactors. This project will develop and demonstrate a high vacuum arc ion source that can reliably deliver high current, low emittance beams of heavy (A=100-238) ions with charg ...

The proposed Ph-II research project will be led by Alameda Applied Sciences Corporation, in collaboration with Jefferson National Accelerator Facility (JLab) and Norfolk State University (NSU) via subcontracts. This team covers the gamut of fundamental research into new Superconducting Radio Frequency (SRF) materials: (i) to first characterize the materials properties such as morphology, grain siz ...

There are numerous fields in which fast pulses of supersonic gas jets are useful. One such application is for the laser wakefield acceleration of electrons. Currently, valves with opening times on the order of hundreds of microseconds and closing times that are even longer are used to supply the gas or small capillaries that are used to control the gas density. This project will develop techno ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

OF THE OVER 600,000 HIGHWAY BRIDGES AND APPROXIMATELY 100,000 RAILROAD BRIDGES IN THE U.S., MANY ARE DIFFICULT TO INSPECT BECAUSE OF LIMITED ACCESSIBILITY. REMOTE INSPECTIONBY UNMANNED AERIAL VEHICLES MAY PROVIDE A SOLUTION TO THIS PROBLEM, BUT INVOLVES CONSIDERATIONS OF VEHICLE SUITABILITY (HELICOPTER, BLIMP DUCTED FAN VEHICLE), THE BRIDGE LOCAL ATMOSPHERIC ENVIRONMENT, AND THE TYPE OF CONTROL (R ...

INERTIAL CONFINEMENT FUSION USING HEAVY ION DRIVERS IS A PROMISING TECHNIQUE TO OBTAIN COMMERCIAL FUSION ENERGY, PRIMARILY BECAUSE OF ITS HIGH EFFICIENCY, HIGH REPETITION RATES, AND THE GOOD RELIABILITY OF PARTICLE ACCELERATORS. THE VERY INTENSE, SHORT DURATION HEAVY ION BEAM PULSES FROM THE DRIVER MUST BE FOCUSED TO A VERY SMALL SPOT TO IGNITE A FUSION PELLET IN A REACTOR. CONSEQUENTLY, IT IS VER ...

THE DEVELOPMENT OF SUPERCONDUCTING RADIO FREQUENCY (RF) ACCELERATOR STRUCTURES HAS PRIMARILY FOCUSSED ON HIGH ENERGYELECTRON ACCELERATORS AND HEAVY ION BOOSTERS FOR ELECTROSTATIC ACCELERATORS. HOWEVER, SEVERAL GROUPS HAVE SUGGESTED THAT THIS TECHNOLOGY MIGHT BE USED TO ACHIEVE A CONTINUOUSLY OPERATING RADIO FREQUENCY QUADRUPOLE (RFQ) ACCELERATING STRUCTURE. THE NORMALLY CONDUCTING RFQ LINEAR ACCEL ...

High Intensity Discharge (HID) lamps are used extensively for large area lighting ¿ such as for parking lots, streets, and warehouses ¿ and are increasingly being used for general lighting in stores and homes. Improving the efficiency of HID lamps would result in significant energy savings. This project will develop an inexpensive, robust coating that is applied to the outside of an HID lamp a ...
