The invention provides a device including a binary pulse input signal converter, the output of which is connected to a counter and to a delay line that includes a plurality of delay elements. The counter and the delay line also receive a clock signal as an input. The delay line is combined with a sampler and analog memory that includes a plurality of storage cells that receive the input signal as input. Each element of the a delay line includes an output connected to a corresponding storage cell of the analog so as to sequentially control the sampling and storage of the input signal in the storage cells.

Very high precision device for measuring the time a signal is input

Large-area, flat-panel photo-detectors with sub-nanosecond time resolution based on microchannel plates are provided. The large-area, flat-panel photo-detectors enable the economic construction of sampling calorimeters with, for example, enhanced capability to measure local energy deposition, depth-of-interaction, time-of-flight, and/or directionality of showers. In certain embodiments, sub-nanosecond timing resolution supplies correlated position and time measurements over large areas. The use of thin flat-panel viewing radiators on both sides of a radiation-creating medium allows simultaneous measurement of Cherenkov and scintillation radiation in each layer of the calorimeter. The detectors may be used in a variety of applications including, for example, medical imaging, security, and particle and nuclear physics.
