Not Available This SBIR Phase I proposal will demonstrate the feasibility of integrating current-perpendicular-to-the-plane (CPP), or vertical giant magnetoresistance (VGMR), memory cells with VLSI silicon electronics. VGMR memory technology enables ultra-high density storage capability which is… More

Input couplers capable of carrying high RF power to superconducting accelerating cavities, such as those used in nuclear physics research, are not only expensive but also difficult to process and condition up to their extremely high operating power and field gradient. Particular problems include:… More

Energy efficient, cost effective, cryogenic distribution system (up to several miles) is strongly commanded for spaceport and in-space cryogenic systems. The use of magnetic levitation by permanent magnets and high temperature superconductors (HTS) results in without mechanical contact and thus, the… More

79766S05 In order to increase proton energy up to 8 GeV in a driver linear accelerator, particles must be accelerated through various stages and three different power levels (25kW, 100 kW, and 210kw). Unfortunately, no power coupler element for these cavities has ever been produced using U.S.… More

79784S05 In superconducting cavities used in nuclear physics research, the detection of impurities on to less than 50 micrometer sizes would enable the cavities to reach the highest possible accelerating fields. Currently available equipment can only inspect flat sheets, which allows for defective… More

79412S05 Superconducting radio frequency (RF) cavities (of which the proposed International Linear Collider (ILC) will need several thousand) require ultra clean vacuum and surface cleanness. A break in a ceramic RF coupler window, with consequent inrushing of air and contaminants, would have… More

There are increasing demands to use high-beam-current, high-radio-frequency (RF) power, S-band cavities in existing and newly planned accelerator projects, in order to produce a very brilliant, broadband, coherent teraherz synchrotron radiation source (or for other purposes). For optimum… More

The ILC accelerator project will require several thousand superconducting radio frequency (RF) cavities with critical RF Input Couplers. These cavities require ultra-clean vacuum and surface cleanness; however, the breakage of a ceramic RF coupler window, with the consequent inrushing of air and… More

The future electron¿ion collider for nuclear physics requires a wide range of collision energies. However, operating a high-energy electron storage ring over a wide energy range imposes significant challenges ¿ i.e., maintaining high luminosity and high electron beam polarization ¿ due to… More

Applications in high energy physics and other fields require the use of thousands of superconducting radio frequency (SRF) cavities made of high purity niobium (Nb) material. However, tantalum, the most prolific of metal inclusions, can cause thermal breakdown in these cavities. This project will… More

High energy physics accelerators and instruments in other fields require the use of thousands of superconducting radio frequency (SRF) cavities that are made of high purity niobium (Nb) material. The purity of Nb is critical for these cavities to reach the highest accelerating fields. Tantalum (Ta)… More
