1. Jerzy Pietraszko, HADES at SIS100 - status GSI Darmstadt, Germany
for the HADES Collaboration
HADES Collaboration Meeting XXV
GSI, Darmstadt, November 19-22, 2012 1

2. HADES at SIS100 (2-10 AGeV), motivation
Aim: Systematic dielectron and hadron spectroscopy in elementary and HICs up to 10 AGeV
No di-electron data exist in this energy range
Enhance production of Vector Mesons:
SIS18  SIS 100 (subthreshold production  above threshold )
better signal, precise line shape determi(nation
reference data for SIS 300
HADES at SIS100:
- proven performance in Au+Au run at SIS18
- easy transfer to FAIR, experienced crew
- can deliver high quality data
But: for pair excess determination a precise knowledge
of the hadronic cocktail is needed
At 2-40 AGeV mainly dominated by η-Dalitz
Normalization to π0 (at SIS18 – TAPS data)
 Calorimeter for HADES
 π0, η measurement
 improved pion suppression

11. HADES at SIS100 - status
SIS100 beam energies:
ions up to 14 A GeV (Au79+ – 11.2 AGeV)
protons up to 29 GeV
HADES is in Module 1 FAIR period together with CBM.
The TDR: "HADES at SIS100" has been submitted to the FAIR management (2009) – positively evaluated.
Collaboration has to be formally established
 to be discussed during the CB meeting today.
Declarations from the HADES collaboration members.
 preliminary task/responsibilities assignment
Open possibility to join by external institutes
MoU of "HADES at SIS100" has to be prepared – urgently need
MoU between HADES and CBM
