A 1.6MeV X-Band traveling wave linear accelerator is being developed in our Lab. in view of X-band Linac R&D and industrial purposes. One section of accelerator structure has been fabricated successfully. In this paper, the RF coupler computer simulation, the constant powerloss collinear load study and the accelerator section development are described in detail. The manufacture technology and s...

Many recent accelerator projects call for the production of high energy bunches of electrons or positrons that are simultaneously short, intense, and have small emittances. Examples of such projects are the Self-Amplified Spontaneous Emission (SASE) FEL’s, such as the Linac Coherent Light Source (LCLS). A major challenge is keeping in check forces that increase beam emittances in accelerator co...

China has endeavored in the field of FEL research since the mid-eighties. Compton regime, Raman regime, Electromagnetic Pumping, Cherenkov FEL, and Harmonic Generator FEL, etc. based on the RF linac accelerator, induction linac accelerator, pulsed-line accelerator, and storage ring have all been developed. These experimental projects are in various stages of development and are discussed in seq...

The use of accelerator-produced spallation neutrons to transmute actinide and long-lived fission-products portends a means to alleviate requirements for deepgeological disposal. The accelerator performance, targetblanket physics, chemical-processing requirements, and overall systems engineering are closely coupled in determining the economic incentives for the Accelerator Transmutation of Waste...

The acceleration gradient of a conventional RF accelerator is limited to about 50 MeV/m. To generate TeV electrons for next generation high energy physics, an RF accelerator would require a distance exceeding 20 km. In this paper, we propose a dielectric-based, multistaged, laser-driven electron linear accelerator operating in a vacuum that is capable of providing 1 TeV electrons in 1 km. Our s...

The IBM DB2 Analytics Accelerator (IDAA) integrates the strong OLTP capabilities of DB2 for z/OS with very fast processing of OLAP workloads using Netezza technology. The accelerator is attached to DB2 as analytical processing resource – completely transparent for user applications. But all data modifications must be carried out by DB2 and are replicated to the accelerator internally. However, ...
