Performance of the projectile fragmentation wall at CELSIUS storage ring

The projectile fragmentation wall [Budzanowski, A. et al., Nucl. Instr. Meth. A482, 528 (2002).] (PFW) is a part of it bigger detection system comprising of the CHICSi detector [Jakobsson, B., Nucl. Phys. News Int. 9:2 22 (1999). Siwek, A., Nucl. Phys., A654, 2695 (1999)] and a recoil detectors array [Kuznetsov, A. V. et al, Nucl. Instr. Meth. A452, 525 (2000)]. The system is designed to register products of proton- and heavy ion-induced reactions at the energies 50-450 MeV/nucleon (see Bo Jakobsson's contribution to this conference). The aim of PFW is to register and identify projectile like fragments emitted in forward direction not covered by the CHICSi detector.
