SimulationsSimulations of detector performance are carried out using GEANT4. Beam properties at FAIR/LEB are predicted to be extreme due to the deceleration process from energies of some GeV/u down to few MeV/u.

Summary

R&D period for the HYDE detector is in progress.

Organization collaboration with SPIRAL2

Working groups

WG1: Mechanical design // would allow part of HYDE to be inside AGATA.

WG2: Simulations: GEANT4 // it looks possible to perform particleidentification and to achieve a reasonable energy resolution.

WG3: Detectors: response to charged particles//SC + PC CVD, monolitic silicon, data base for DPSA using Si

WG4: Particle I.D. // neural networks look promising.

WG5: FEE: just started looking to state of the art; some work inprogress.

Funding: looks alright for one year.
