Description
The Single Particles, Clusters, and Biomolecules and the Serial Femtosecond Crystallography (SPB/SFX) instrument at the European XFEL (EuXFEL) has been in operation since 2017 [1]. This instrument is focused on coherent diffractive imaging (CDI) and serial femtosecond crystallography (SFX) methods. Intense (mJ), ultrashort (fs) and MHz X-ray FEL pulses at the European XFEL also allow the collection of damage-free data with fast data acquisition. The combined experiment with optical lasers gives the opportunity for ultrafast pump-probe measurements [2]-[3]. EuXFEL operates in the so-called ‘burst mode’ with a burst duration of 600 s at a repetition rate of 10 Hz. Each burst can have a single pulse or a train of pulses with an intra-burst repetition rate of up to 4.5 MHz. This unique pulse structure opened MHz data rate measurement and also microsecond time-resolution experiments [4]-[5]. Recently, MHz X-ray microscopy was established and opened for user program [6]-[7]. We will introduce laser-induced fragmentation of droplet experiment using unique pulse structure and discuss on microsecond measurements at the SPB/SFX instrument of the EuXFEL.
