Title:
TIME-RESOLVED MEASUREMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2004/113888
Kind Code:
A1
Abstract:
A time-resolved measurement apparatus (100) acquires a detection timing pulse from an output terminal (34) provided to a micro-channel plate (30) in a photomultiplier (14). A position time measurement circuit (16) produces a signal indicative of a time difference between the detection timing pulse and a reference time pulse synchronized with an excitation of a material (10) and sends the produced signal to a data processing apparatus (18). The data processing apparatus stores this time difference as a detection time point of photoemission. The data processing apparatus corrects the detection time point in accordance with the distance between the output terminal and the occurrence position of the detection timing pulse on the micro-channel plate. In this way, the precision of the time-resolved measurement is enhanced.
