Tomography by the maximum entropy method for the W7-AS and W7-X multichannel bolometer systems

Amaximum entropy approach has been applied to the tomographic inversion of the line integrated measurements of radiation power ux by a multichannel bolometer system. This method was applied to a H-mode discharge in the W7-AS stellarator, with increasing radiation from the plasma core after the transition being observed. Also a neutral beam injection discharge was investigated, and the time evol...

Collective deceleration: toward a compact beam dump

With the increasing development of laser accelerators, the electron energy is already beyond GeV and even higher in near future. Conventional beam dump based on ionization or radiation loss mechanism is cumbersome and costly, also has radiological hazards. We revisit the stopping power of high-energy charged particles in matter and discuss the associated problem of beam dump from the point of v...

Plc-based Beam Charge Interlock System for Radiation Safety in the Kekb Injector Linac

A new PLC-based beam charge interlock system is under development for radiation safety and machine protection in the KEKB injector linac. This system restricts integrated amounts of beam charges passing through several locations along the linac before they are injected into four different storage rings (KEKB ee storage rings, PF, PF-AR). The beam charges are measured using wall current monitors...

Database Structures and Interfaces for W7-X

The W7-X Experiment of the IPP, under construction in Greifswald Germany, is designed to operate in a quasi-steady-state scenario. The database structures and interfaces used for discharge description and execution have to reflect this continuous mode of operation. In close collaboration between the control group of W7-X and the data acquisition group a combined design of the data structures us...

Apertures in the Lhc Beam Dump System and Beam Losses during Beam Abort

The LHC beam dumping system (LBDS) is used to dispose accelerated protons and ions in a wide energy range from 450 GeV up to 7 TeV. An abort gap of 3 μs is foreseen to avoid sweeping particles through the LHC ring aperture. This paper gives a brief overview of the critical apertures in the extraction region and the two beam dump lines. MAD-X tracking studies have been made to investigate the im...
