Development of a novel high-resolution TOF spectrometer with tracking capabilities for photo-fission fragments and beams of exotic nuclei^* — •K.M. Kossev¹, N. Nankov^1,2, A. Wagner¹, E. Grosse¹, A.

An advanced double-arm TOF spectrometer is under development. The spectrometer is designed to have high time resolution (σ<100 ps) and tracking capabilities[1]. It is proposed to be used for high-precision identification of exotic nuclei for the planned photo-fission experiments at the ELBE radiation source in Rossendorf and for experiments with beams of exotic nuclei at GSI. Recently, the position sensitivity of the TOF detector has been optimized and a spatial resolution better than 1 mm in both x-and y-directions has been achieved. We present the results for the optimized imaging properties of the TOF detector.
