Ceramic Matrix Composites (CMCs) can provide excellent high temperature performance in a wide range of applications (e.g., jet engines). However, designing and manufacturing components from CMCs continues to represent a challenge to industry. AltaSim Technologies is currently developing design tools for subject matter experts at large corporations with significant computational resources. Small to ...

Short electron beam pulses (subpicosecond) are central to many of the next generation light source initiatives, like X-Ray Free Electron Lasers. These FELs are based on linear accelerators which produce at the output of the last compressor an electron beam with a residual chirp to compensate for wakefield effects through the rest of the accelerating stage. It is required that this small but signif ...

The total length and hence cost of the ILC is in part due to limitations of its superconducting standing wave accelerating cavities. We have invented a new technology that can reduce the total length of the ILC by 2/3. We have developed a design for a traveling wave superconducting accelerating structure that supports a larger gradient compared to SW structures, and also allows less wasted space ...

The lattice period in the low energy section of a proton accelerator is required by the physics to be as short as possible; however, the required number of beamline components per period is high. By gradually increasing the diameter of the low energy accelerating cavities (giving them a conical shape) and staggering the rotation of the cavities a considerable reduction in the space required is obt ...

One of the most attractive features of dielectric based accelerators are their potential capability of operating at ultra-high gradients, which is highly desirable for future high energy collider designs, as well as for industrial and medical accelerator applications. This prediction of ultra-high gradients is widely accepted but has never been verified because of experimental difficulties. We pro ...

Multipactor discharges in dielectric accelerating structures are a major limitation on the performance of this otherwise very promising technology for future high energy physics machines and other applications. We will experimentally study a new approach, using a proper external solenoid field, to completely suppress multipactor. This approach has been theoretically studied and verified in a 3-D n ...

Fast electronic tuning of SC cavities is a critical issue for optimized rf power distribution for accelerators. The overall goal of the program is to develop an L-band externally-controlled fast ferroelectric tuner for controlling the coupling of superconducting RF cavities for the future linear colliders. Recently proposed planar tuner design requires new elements to be developed made of an impro ...

These requirements demand that the undulators have short periods (around 1.5 cm) and high peak magnetic fields (around 1.6 tesla). For the windings of such undulators the solicitation also requests the use of new superconducting materials such as improved Nb3Sn superconductors and high temperature superconductor such as YBCO tape, and the development of appropriate coil manufacturing techniques. H ...

U.S. Department of Energy, Office of Basic Energy Sciences (BES) under Topic 11 ADVANCED SOURCES FOR ACCELERATOR FACILITIES Subtopic (b), Undulator Radiation Sources, is seeking superconducting undulators that can generate tunable (i.e. variable field) mono- chromatic x-ray beams in the 2-30 keV photon energy range from medium-energy (2-3 GeV) synchrotrons. These requireme ...

This proposal is submitted in response to the SBIR/STTR High Energy Physics Solicitation Topic 30(a). High-Field Superconductor and Superconducting Magnet Technologies for High Energy Particle Colliders, (a) High-Field Superconducting Wire Technologies for Magnets. The need is for strands that can operate in the 15/17T or higher regime, and have deff values of 30 m or less, with non-Cu Jc values a ...
