Development of a measurement system enabling the reconstruction of gamma-ray time spectra by simultaneous recording of energy and time information

Abstract

We developed a measurement system that enables the reconstruction of γ-ray time spectra in cascade decay schemes. As this system records all the time and energy information of γ-rays, reconstruction is possible after the measurement. Therefore, the energy regions for the γ-ray identification can be optimized in complicated cascade decay schemes. Moreover, in this system we can record data with time-dependent parameters of external perturbations, such as applied magnetic fields, and consequently we can investigate the correlations and responses of γ-rays to the perturbation. This property fulfills the demands required for quantum information research with γ-rays.
