Radiation protection at high energy electron accelerators.
An overview is presented of radiation protection at high energy electron accelerator facilities. By 'high energy' is meant the energy domain beyond a few tens of MeV, where electromagnetic showers are the determining and dominant factor for beam interactions with matter. The basic components of electron accelerators are described and their potential impact on radiation safety. The paper then co...
متن کاملOperational radiation protection in high-energy physics accelerators: implementation of ALARA in design and operation of accelerators.
This paper considers the historical evolution of the concept of optimisation of radiation exposures, as commonly expressed by the acronym ALARA, and discusses its application to various aspects of radiation protection at high-energy accelerators.
متن کاملShielding high energy accelerators.
After introducing the subject or shielding high energy accelerators, point source, line-of-sight models, and in particular the Moyer Model, are discussed. Their use in the shielding of proton and electron accelerators is demonstrated and their limitations noted, especially in relation to shielding in the forward direction provided by large, flat walls. The limitations of reducing problems to th...
متن کاملTowards Very High Energy Accelerators
The development of a new generation of colliders beyond the LHC is central to the future of high-energy physics. As was clearly pointed out by Lykken [1], the prospects for high-energy physics may be limited by our ability to build them. This paper describes possibilities for these colliders and some of the challenges we face in building them. None of the fundamental ideas that underly the adva...
متن کاملDosimetry at high-energy accelerators
R É S U M É Les problèmes de la dosimetric dans les champs de rayonnements ionisants diffusés autour des accélérateurs de haute énergie sont présentés. Après une courte introduction sur l'historique des grandeurs physiques utilisées pour l'acquisition de l'équivalent de dose, les techniques diverses pour la dosimétrie dans des champs mixtes à haute énergie sont décrites, en commençant par des m...
