Reconstruction of Particle Initial Energy and High-Resolution Timing by the ANKE Silicon Tracking Telescopes. — •Vladimir Leontyev for the ANKE collaboration — FZ-Juelich, Juelich, Germany

At ANKE, a Silicon Tracking Telescope (STT) is under development, which has started being used for spectator detection, luminosity determination and polarimetry in recent experiments, and which will be an essential detector component for many of the planned future measurements. Its attractive features are a precise reconstruction of a particle initial energy (∼ 1%) and timing capability (< 1 ns FWHM). In order to investigate the energy resolution, a test setup, based on α-sources (²⁴¹Am, ²⁴⁴Cm), has been installed in our laboratory. For timing, the front-end electronics has been equipped with two different readout-chips: VA32TA2 (ideas, Norway) and MATE3 (Saclay, France). A combined implementation of these chips allows to improve a performance, as it was found using test setups with α- and β-sources. Results of the ongoing development will be presented.
