As quantum computers become available to the general public, need has arisen train a cohort of programmers, many whom have been developing classical computer programs for most their careers. While currently less than 100 qubits, computing hardware is widely expected grow in terms qubit count, quality, and connectivity. This review aims explain principles programming, which are quite different from with straightforward algebra that makes understanding underlying fascinating mechanical...
X-ray free-electron lasers (FELs) are cutting-edge research instruments employed in multiple scientific fields capable of analyzing matter with unprecedented time and spatial resolutions. Time-resolved measurements electron photon beams essential FELs. Radiofrequency (RF) transverse deflecting structures (TDSs) a fixed streaking direction standard diagnostics to measure the temporal properties beams. If placed after undulator FEL facility, TDSs can also be reconstruct power profile pulses....
We demonstrate the generation of widely tunable two-color x-ray free-electron laser (FEL) pulses at SwissFEL. In a split-undulator configuration, each color is produced in different undulator section, and chicane between two sections allows for variable time separation up to 500 fs. show an unprecedented photon energy ratio colors about three (350 915 eV), with individual pulse having peak power few gigawatts duration down femtosecond level. Moreover, we reduction required length via optical...
SwissFEL has a unique capability, among the normal conducting linac-based light sources, to simultaneously serve two separate undulator lines (Aramis and Athos) up machine repetition rate of 100 Hz using double bunch operation mode. It increases twice experiments throughput facility with modest additional investment. Two electron bunches spaced 28 ns apart are extracted from cathode by laser pulses individually controlled rates. The accelerated about 3 GeV in main linac same rf macropulse....
Time-resolved diagnostics are fundamental for x-ray free-electron lasers (FELs). Radio-frequency (RF) transverse deflector structures (TDSs) typically employed to characterize the temporal properties of electron beams driving FELs. In this article, we present time-resolved measurements with a resolution below one femtosecond using C-band RF TDS at SwissFEL, FEL facility Paul Scherrer Institute in Switzerland. The sub-femtosecond is partially achieved due an optimized optics setup and fits...
Through an interaction of theory and optimization-guided design, we have developed a novel bunch compression scheme based on asymmetric double emittance exchange (DEEX) with greatly reduced coherent synchrotron radiation (CSR) effects. First, discuss the benefits phase space exchange-based compressor (BC) in comparison to chicane-based counterpart approximation linear single particle dynamics respect microbunching instabilities driven by longitudinal charge forces. We present simulation...
