High spatial resolution photon detection through event centroiding. (a) Single-photon footprints detected by Timepix readout. (b) Enlargement of the area indicated by a dashed rectangle in (a), showing footprints of two photons in more detail. (c) Fraction of a high-resolution image obtained with full-field UV illumination of the MCP/Timepix detector. Individual pores of the MCP are resolved in the image. Two black spots correspond to the triple-point defects present in this MCP (crushed MCP pores at the points where three hexagonal multifibers meet). |
