Ultra-fast heating effects in an aqueous salt solution investigated via X-ray split-and-delay technique

We present a split-and-delay study on an aqueous salt solution. We employed SACLA split-and-delay optics to split each FEL pulse into pair of two pulses and delayed one of them. The sample was delivered via a liquid jet system which was illuminated by the double-pulses as a function of the delay time from 50 fs to 1 ps. The results indicate beam induced heating effects in the sample from 250 fs.
