Abstract

The new accelerator SIS100 and the Super-FRS will be built at the international Facility for Antiprotons and Ion Research FAIR. The synchrotron SIS100 is a core part of the FAIR facility which serves for acceleration of ions like Uranium up to 2.7 GeV/u with intensities of 3x1011 particles per second or protons up to 30 GeV with intensities of 5x1012 particles per second. The Super-FRS is a superconducting fragment separator, it will be able to separate all kinds of nuclear projectile fragments of primary heavy ion beams including Uranium with energies up to 1.5 GeV/u and intensities up to 3x1011 particles per second. During operation activation of several components, especially the production target and the beam catchers will take place. For handling of highly activated components it is foreseen to have a hot cell with connected storage place. All calculations for the optimisation of the shielding design of the SIS100, the Super-FRS and the hot cell were performed using the Monte Carlo code FLUKA, results are presented.

Extracted from the preaccelerator, high-intensity ion beams will be injected into the SIS100 and accelerated to the energy demanded by the experiments

Summary

Introduction

FAIR [1, 2], Facility for Antiproton and Ion Research, will be a new international accelerator facility for the research with antiprotons and ions. It will be based upon an expansion of the GSI Helmholtz Centre for Heavy Ion Research which is situated in Darmstadt, Germany. In this paper the radiation protection aspects of the SIS100 and the Super-FRS are discussed. They are the crucial parts of the facility in terms of radiation production.
