Sentences with phrase «electron source»

HiRES is a new capability that builds on the Advanced Photo - injector Experiment (APEX), a prototype electron source for advanced X-ray lasers.

Field emission electron sources catch scientists» attention due to its ability to provide intense electron beams that are about a thousand times denser than conventional thermionic cathode (like filaments in an incandescent light bulb).

SLAC's instrument benefits from a high - energy, ultrabright electron source originally developed for the lab's femtosecond X-ray laser, the Linac Coherent Light Source (LCLS), a DOE Office of Science User Facility.

In addition to a new accelerator, LCLS - II requires a number of other cutting - edge components, including a new electron source, two powerful cryoplants that produce refrigerant for the niobium structures, and two new undulators to generate X-rays.

The development of these new nanohybrid emitters opens new prospects for their application as cold cathodes in portable, low voltage, highly brilliant electron sources.

The breakthrough was based on the development of ultra-bright electron sources that dates back to the 2003 work.

Daniele Filippetto, a Berkeley Lab scientist who is leading HiRES, has for much of his scientific career focused on building electron sources, also called «electron guns,» that can drive advanced X-ray lasers known as «free - electron lasers.»

A unique rapid - fire electron source — originally built as a prototype for driving next - generation X-ray lasers — will help scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) study ultrafast chemical processes and changes in materials at the atomic scale.

«A novel approach for high performance field emission electron sources.»

Antibodies produce up to 500 mole equivalents of H2O2 from1O2 *, without a reduction in rate, and we have excluded metals or Cl — as the electron source.

On the basis of isotope incorporation experiments and kinetic data, we propose that antibodies use H2O as an electron source, facilitating its addition to 1O2 * to form H2O3 as the first intermediate in a reaction cascade that eventually leads to H2O2.

We now show that this process is catalytic, and we identify the electron source for a quasi-unlimited generation of H2O2.

«What we additionally need is just an electron source.

The process, which was described in the Angewandte Chemie journal, requires only an electron source in addition and should therefore be usable on a broad scale in future.

About six years ago, researchers in the USA for the first time described how certain microorganisms grow on a cathode, bind CO2, and use the cathode as the only energy and electron source.

In a traditional X-ray machine, a filament emits electrons when it is heated above a certain threshold, and those electrons fly through the body and hit a metal electrode on the other side, creating images; CT scans produce three - dimensional images by rotating the electron source.

We would take a conventional electron microscope, put in one of our tips as the electron source and render the microscope instantly improved and capable of finer resolution.»

Field emission electron sources can provide intense electron beams that are about a thousand times denser than conventional thermionic cathodes (like filaments in an incandescent light bulb).

At left (on blue base) is APEX, the electron source for HiRES.
