Challenges for solid state tracking detectors in nuclear physics experiments at FAIR — •Oleg Kiselev — Institut für Kernchemie, Universität Mainz

A versatile reaction setup with excellent efficiency, acceptance, and resolution for kinematically complete measurements of reactions with high-energy radioactive beams will be installed at the focal plane of the new fragment separator at the new accelerator facility FAIR planned at GSI. The combination of a superconducting large-acceptance dipole with high-resolution tracking and time-of-flight detectors will provide significant improvements in momentum resolutions for heavy fragments, light-charge particles, and neutrons. The set of thin double-sided Si microstrip detectors will be developed for the detection of the light recoiling particles in a wide range of energies. The system should be able to work with the different target, including the liquid hydrogen and helium targets placed inside a ball of the crystal calorimeter. The unique feature of the target recoil system is a high angular, energy resolution and an identification of the particles for a wide variety of scattering experiments, such as heavy-ion induced electromagnetic excitation, knockout and fragmentation, or light-ion (in)elastic and quasi-free scattering in inverse kinematics. The results of the design studies, simulations and the first beam test of the prototypes will be presented.
