We present the implementation of the silicon pixel device Timepix for position and energy sensitive detection of ultra-cold neutrons (UCN) with efficiency of 70% and spatial resolution of 5.3 um. A layer of 400 ug/cm2 of 6LiF deposited onto the Timepix sensor surface was used as a neutron converter. The energy of each detected neutron is measured using standard TOF (Time-Of-Flight) 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.
