Schematic overview of the pump–probe RSXS measurement system. The RF master oscillating signal, which is the reference signal for the storage ring, is separated into three timings by the timing module to synchronize the oscillator, the laser emission of the regenerative amplifier and the data acquisition system. The laser beam introduced into the vacuum path irradiates the sample almost coaxially with the soft X-ray beams. In this study, the photon energy of the laser is 2.41 eV (515 nm) and that of the X-rays is approximately 530 and 645 eV corresponding to the O K- and Mn LIII-edges, respectively. A constant-fraction discriminator is abbreviated as CFD.
