Query: Development of a measurement system enabling the reconstruction of
  gamma-ray time spectra by simultaneous recording of energy and time
  information   We developed a measurement system that enables the reconstruction of
{\gamma}-ray time spectra in cascade decay schemes. As this system records all
the time and energy information of {\gamma}-rays, reconstruction is possible
after the measurement. Therefore, the energy regions for the {\gamma}-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 {\gamma}-rays to the
perturbation. This property fulfills the demands required for quantum
information research with {\gamma}-rays.
