Since the SAC report was very positive on our Letter of Intend, we decided to start the collaboration on preparing the calorimeter for High Energy gamma-rays. The aim of the kick-off meeting in Orsay was to establish the organization of the collaboration and discuss the following points of the AGENDA:
______________________________________________________
1) Review what technical effort our groups can offer in the short and long
term, as far as manpower and resources (AM, .....)
2) Review the status of new materials such as LaBr(Ce) to see if it will a)
supply what is needed b) at a realistic cost and c) on an appropriate time
scale (OD,...)
3) Review the existing arrays in terms of their suitability and also their
potential availability in the long term (AM, JAS...)
4) Review this in the context of R&D activities related to FAIR and RIKEN and whether we can form a useful linkage with these ( EXL: JAS)
5) Funding issues (JPW, Marc Rosseau, AM)

2) Review the status of new materials such as LaBr(Ce) to see if it will a)
supply what is needed b) at a realistic cost and c) on an appropriate time
scale (OD,...)
O. D. presentation: New materials
The costs and time scale will be defined later
3) Review the existing arrays in terms of their suitability and also their
potential availability in the long term (AM, JAS...)
HECTOR: Milano-Krakow-Copenhagen collaboration: available upon agreement with Milano
Chateau de Crystal: permanent at GANIL
TAPS??? (AM will investigate)
GSI Crystal ball?! (after 2009 in GANIL)
____________________________________________________________________________
4) Review this in the context of R&D activities related to FAIR and whether
we can form a useful linkage with these ( EXL, R3B : JAS,)
___________________________________________________________
5) Funding issues (JPW, Marc Rousseau, AM, FA,�)
JPW: ANR: beginning of every year. Criterion: people have to have something done. Gamma-cal: white project. Conclusion � apply next year?
LEA: GANIL-Poland: remember to insert calorimeter
LEA: GANIL-LNL: remember to insert calorimeter
IN2P3-Poland: collaborations Wieleczko-Maj, Kmiecik-Azaiez approved
MR: IPHC asked already for 5kEuro for detectors for 2007
AM: NUPNET@FP7
Care about FP7 will be taken by Faical Azaiez
Application for polish Grant � next year? (AM will take care )
__________________________________________________________
6) Finding a name for our collaboration (JPW proposes: CHERMES or HERMES)
HERMES: High Energy gamma-rays and Multiplicity and Energy-summeasurement
__________________________________________________________________
anddefining the Working groups and their coordinators:
Geant4 simulation WG:Olivier Stezowski (Lyon)
WG for Calorimeter scenarios:David Jenkins (York)
Mechanical design WG:Sandrine Courtin (Starsbourg)
Detectors and electronics WG:Olivier Dorvaux (Strasbourg) & Marek Moszynski (Swierk)
Theory background WG:Christelle Schmidt (Lyon)
Connections to other detectors WG:Marc Rousseau (Strasbourg)
Preparation of FP7 project WG:F. Azaiez (Orsay)
Other WGs will be defined later if needed
__________________________________________________________________________
7) Defining a Steering Committee and its role:
The steering committee shall reflect the declared potential (manpower and resources) of theparticipating groups, and should be rather small.
Therefore we propose the following members of the HERMES Steering Committee (HSC):
A. Maj (Krakow, PL), D. Jenkins (York, UK),J.A. Scarpaci (Orsay, F), J.P. Wieleczko (GANIL, F)),
M. Moszynski (Swierk, PL), J. Gerl (GSI, D) , F. Azaiez (Orsay/GANIL, F),
Ch. Schmidt (Lyon, F), S. Courtin (Strasbourg, F), 1 person from Mumbai, India (to be defined)
G. de Angelis (Legnaro, I)
Steering Committeemighty extended in future.
Managing Board: HERMES Steering Committee (HSC) + WG coordinators
_____________________________________________________________________
8) Defining the Project Coordinators:
It was decided to that the LoI spokespersons will become the Project coordinators:
Project spokesperson (and scientific coordinator):Adam Maj
Coordinator for financial and administrative issues:Jean-Pierre Wieleczko
Coordinator for technical issues:David Jenkins
Coordinator for synergy with SPIRAL2, FAIR and RIKEN :Jean-Antoine Scarpacci
_________________________________________________________
9) Set the priorities and set the steps.
Setup the main page of the HERMES collaboration (Krakow)
Simulation WG: establish the information exchange way, server, meeting (Stezowski)
Detector WG: contact Marek Moszynski and St. Gobain,.. establish the information exchange way (Dorvaux)
Mechanical WG: discussion with John Simpson, discuss with other institutes (Courtin, Jenkins)
Theory WG: contact people, create unified theory (Schmidt)
________________________________________________________
10) review of the referee�s comments of LO8 - how to proceed with this (AM, ..)
Possible key experiments, to be discussed during next meeting:
Heavy-ion radiative capture in e.g. 28Si, Jacobi shapes in neutron rich 120Cd
The experiment for 120Cd will cover both the reaction mechanisms, GDR, and shape evolution aspects, and I will use the most intense radioactive beam at SPIRAL2.
Heavy-ion radiative capture wull use the existing LINAG beams
____________________________________________________________________
11) Other issues
D. Jenkins: I wonder whether such a calorimeter could be used outside of the context of SPIRAL2.
E.g. in REX-ISOLDE, where it could be used for Coulomb excitations ortransfer measurements.
There are many cases where the gamma energies are known, but yields are very low and scintillators could help.
A. Maj: such calorimeter could also be usedin being prepared
�distributed Large Scale Facility�: Warsaw-Praque-Debrecen-Zagreb-Bucarest-Athens.
And also in HISPEC@NUSTAR@FAIR
