The Laser Electron Photon Experiment at SPring-8 (LEPS) is an experiment producing high-energy photon beams by the inverse Compton scattering of photons upon the 8 GeV electrons of the SPring-8 synchrotron. These are then used for various particle physics experiments on hadrons. The first beam was produced in 1999, and data-taking commenced in ...
The SPring-8 Angstrom Compact free electron LAser, referred to as SACLA (pronounced さくら (Sa-Ku-Ra)), is an X-ray free-electron laser (XFEL) in Harima Science Garden City, Japan, embedded in the SPring-8 accelerator and synchrotron complex. [1] [2] When it first came into operation 2011, it was the second XFEL in the world and the first in ...

Charge coupled device (CCD) cameras were first applied to transmission electron microscopy in the 1980s and later became widespread. [3] [4] For use in a TEM, CCDs are typically coupled with a scintillator such as single crystal Yttrium aluminium garnet (YAG) in which electrons from the electron beam are converted to photons, which are then transferred to the sensor of the CCD via a fiber ...

The model is derived by modeling an electron orbiting a massive, stationary nucleus as a spring-mass-damper system. [2] [3] [4] The electron is modeled to be connected to the nucleus via a hypothetical spring and its motion is damped by via a hypothetical damper. The damping force ensures that the oscillator's response is finite at its ...
An ultrabright electron beam has been defined as having >10 A/cm^2 with spatial coherence of >1 nm. [1] This level of energy in that small of a coherence is a large technical problem, not only in the production of such a beam, but also how to use the beam without destroying the sample in the process of characterization.

SSRL is a National User Facility which provides synchrotron radiation, a name given to electromagnetic radiation in the x-ray, ultraviolet, visible and infrared realms produced by electrons circulating in a storage ring (Stanford Positron Electron Asymmetric Ring - SPEAR) at nearly the speed of light. The extremely bright light that is produced ...
