An MCNPX accelerator beam source

BEAM : an accelerator for speech recognition

BEAM is a hardware accelerator that has been designed and built for real-time execution of the SPHINX speaker-independent, continuous speech recognition system and similar systems. SPHINX on BEAM is able to recognize sentences from a 1,000 word vocabulary and a perplexity 60 grammar in about 1.3 times real time. BEAM does not use any custom integrated circuit. This report describes the architec...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

An Electron Source for a Laser Accelerator*

Laser accelerators offer the promise of producing attosecond electron bunches from a compact accelerator. Electron source requirements for laser accelerators are challenging in several respects, but are achievable. We discuss these requirements, and propose an injector design. Simulation and design work for essential components for a laser accelerator electron source suitable for a high energy ...

Accelerator Optimization through Beam Diagnostics

A comprehensive set of beam diagnostics is key to the successful operation and optimization of essentially any accelerator. The oPAC project received 6 M€ of funding within the EU's 7th Framework Programme. This has allowed to successfully train 23 Fellows since 2011. The network joins more than 40 institutions from all around the world, including research centers, universities and private comp...

Continuous Electron Beam Accelerator Facility,

We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the γ * p → ∆ form factors. Our results are in agreement with existing experimental data. We predict that the ratio G * E (Q 2)/G * M (Q 2) is small for all accessible Q 2 , in contrast to the pQCD expectations that G * E (Q 2) → −G * M (Q 2).
