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 an extension to 2-dimension of the delay line technique 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 pixels which pitch is smaller than the MCP tubes diameter and that are interconnected in an original way. The new scheme leads to an excellent granularity without suffering from the usual ambiguity encountered in the X-Y strip-based readout systems and still operated with a much smaller number of electronic channels with respect to a pixel-based readout one.
Spatial and time measurement systems based on the two concepts have been designed and produced. Both were individually tested and validated. The two systems were then assembled together to read out the signal produced by alpha source placed on a stack of two MCP placed in a vacuum setup in order to validate the whole concept.
In this paper the PICMIC concept, the realization of the to two measurement systems as well as the first results obtained with the prototype are presented.
Development of new generation of MCP using nanotechnologies will also be presented and the expected performances of these new detectors called NanoChannel Plate (NCP) will be discussed and the steps towards such detectors will be enumerated.
