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, ...
