Radiological protection evaluation of the Bucharest Tandetron 3 MV accelerator

Abstract

Low energy heavy charged particle accelerators are generators of ionizing radiation, due to the ion beam interactions into the machine components, targets and surrounding materials. Nowadays there are available computational tools allowing realistic estimates of radiation doses and residual activity of the activated components. These evaluations are further used to design the radiological safety system required by licensing and operation of the equipment.This paper presents results of measurements and numerical simulations of the radiation doses and residual activity, at the recently commissioned Bucharest 3 MV Cockcroft-Walton type Tandetron accelerator presently used mainly for Ion Beam Analysis (IBA) research.

Superintense Laser-driven Ion Beam Analysis

“…As a consequence, al the available IBA techniques have been developed considering only monochromatic, conventional accelerator-based ion beams. Conventional ion sources are invariably affected by a number of limitations: non-tunable energy, radioprotection issues 9 , high costs, non-portable size. Ion sources driven by superintense lasers represent a very interesting alternative 10 .…”
