Outline

Introduction

HESR: High-Energy Storage Ring

Prototyping of HESR components

Beam Experiments at the Cooler Synchrotron COSY

Summary

Contribution to ELENA


Facility for Antiproton and Ion Research

SIS18

SIS100

p-Linac

HESR

Antiprotons

Production

Target

CR/RESR


HESR design driven by the requirements of PANDA:

Antiprotons with 1.5 GeV/c ≤ p ≤ 15 GeV/c

High luminosity: 2·1032 cm-2s-1

Thick targets: 4·1015 cm-2

High momentum resolution: Δp/p ≤ 4·10-5

Phase space cooling

Long beam life time: >30 min

Criteria for the Layout of the HESR


HESR with PANDA and Electron Cooler

COSY

HESR

HESR Consortium: Germany (Jülich, GSI, Mainz), Romania and Slovenia


HESR Prototyping and Tests

Example: Beam Cooling with WASA Pellet Target

  • Injected beam

  • Beam heated by target

  • + stochastic cooling

  • d) + barrier bucket


Hadron Physics with Antiprotons

Sophisticated accelerators
