AbstraktAbstract
We present an implementation of the silicon pixel device Timepix for position and energy-sensitive detection of ultra-cold neutrons (UCN) with an efficiency of 70% and a spatial resolution of 5.3 mu m. A layer of 400 mu g/cm(2) of (LiF)-Li-6 deposited onto the Timepix sensor surface was used as a neutron converter. The energy of each detected neutron is measured using standard time-of-flight (TOF) technique. Thus, for each detected neutron the position and energy is determined. We demonstrate this technique on the real-time measurement of energy- and position-dependent reflection of UCNs from a bent foil of stainless steel making direct visualization of total reflection angle for different neutron energies.
