Description
The PICosecond subMICron (PICMIC) is a new detection concept that intends to simultaneously exploit the remarkable intrinsic spatial and time precision of the MicroChannel Plate (MCP) detectors. The concept is itself made of two new ones. The first is similar in principle to the GPS system and allows, with a limited number of electronic channels, a precise measurement of the arrival time of particles crossing the MCP. The second, conceived to measure the position of these particles, uses tiny pixels that are interconnected in an original way. The new scheme leads to an excellent granularity without suffering of the usual ambiguity encountered in the strip-based readout systems while operated with a much smaller number of electronic channels with respect to a pixel-based readout one.
Both the spatial and the time measurement systems were individually tested and validated before to be assembled in a first prototype. The prototype equipped with an alpha source allowed the validation of the whole concept. We present in this paper the PICMIC concept, the realization of the two measurement systems as well as the first results obtained with the prototype and how we intend to trasnsofrm it into a photon detector preserving the excellent MCP spatial granularity.
