Abstract–Coesite and stishovite are high-pressure silica polymorphs known to have beenformed at several terrestrial impact structures. They have been used to assess pressure andtemperature conditions that deviate from equilibrium formation conditions. [...]

Acceleration and manipulation of electron bunches underlie most electron and X-ray devices used for ultrafast imaging and spectroscopy. New terahertz-driven concepts offer orders-of-magnitude improvements in field strengths, field gradients, laser synchronization and compactness relative to conventional radiofrequency devices, enabling shorter electron bunches and higher resolution with less infrastructure while maintaining high charge capacities (pC), repetition rates (kHz) and stability. [...]

The SINBAD (Short INnovative Bunches and Accelerators at DESY) project is a dedicated, long-term accelerator research and development facility currently under construction at the DESY Hamburg campus, aiming to provide an infrastructure for developing ultrafast science and several types of novel high-gradient accelerators. We present the design of the magnetic lattice as well as the start-to-end simulation results for ultrashort electron bunch generation at the ARES (Accelerator Research Experiment at SINBAD) linac, which is one of the twoexperiments at the SINBAD facility.

A transverse deflecting structure (TDS) is a well-known device for characterizing the longitudinal properties of an electron bunch in a linear accelerator. The standard use of such a cavity involves streaking the bunch along a transverse axis and analysing the image on a screen downstream to find the bunch length and slice properties along the other transverse axis.
