Web19 Jan 2024 · The X-ray free-electron laser of the Pohang Accelerator Laboratory (PAL-XFEL) was opened to users in 2024. Since then, significant progress has been made in PAL-XFEL operation and beamline experiments. This includes increasing the FEL pulse energy, increasing the FEL photon energy, generating self-seeding FEL, and trials of two-color … Web11 Jun 2024 · The European XFEL in Hamburg is driven by a superconducting linac, which delivers up to 27,000 pulses per second, delivered in 10 separate bunches, at wavelengths from nanometres to below 1 Å....

WebSatellite remote sensing is one of the main techniques of monitoring severe weather conditions over the ocean. The principal difficulty of the existing algorithms of retrieving wind based on dependence of microwave backscattering cross-section on WebWith this in mind, we are pleased to announce a terahertz workshop, with the aim to find the most scientifically promising strategies to combine terahertz radiation with the unique X … integrity goals
Terahertz wave parametric source - IOPscience
WebMultilayer Laue lenses (MLLs) made from WC and SiC were previously used to focus megahertz X-ray pulse trains of the European XFEL free-electron laser, but suffered damage with trains of 30 pulses or longer at an incident fluence of about 0.13 J/cm 2 per pulse. Here, we present numerical simulations of the heating of MLLs of various designs, geometry … WebThe Centre for Terahertz Science and Engineering (CTSE), hosted by the Faculty of Engineering, supports a wide range of activities across the extended terahertz (THz) spectrum, from ca. 100 GHz to 100 THz – coving the sub-terahertz (millimetre-wave), terahertz (submillimetre-wave) and ‘over the THz horizon’ (thermal infrared) bands. While … Web19 Mar 2024 · The UK has formally joined the European XFEL, a super-bright X-ray laser. The machine, which is sited in Germany, produces high-energy pulses that are focussed on a target at the end of a... joe smith musician
