Abstract
- Abstract: A picosecond stroboscopic pulse radiolysis system which consists of a femtosecond laser and a picosecond L-band linear accelerator (linac) is demonstrated. A newly installed femtosecond laser system operated at 960Hz can cover a wide region of wavelength ranging from <300nm to 10μm, although the upper limit is 1.7μm to date because of the sensitivity of photodetectors. In order to achieve a high accuracy of synchronization between the laser and the linac, a new timing and synchronization circuit was developed. A double pulse detection method was applied for the new system, resulting in doubling of the improvement in signal-to-noise ratio. The time resolution and time jitter were estimated from the rise time of hydrated electrons at 600nm, and the transient absorption kinetics of electrons in n-dodecane was measured at 1300nm.
