    Oral

    Electron emission from a material through an interface to vacuum or another material is a fundamental process in cathode, diode, ionization, electric contact and many other areas. Depending on the energy used, it can be broadly characterized into 3 different processes known as thermionic emission TE (by thermal energy), field emission FE (by quantum tunneling) and photoemission PE (by...

    3.2 Intense Electron and Ion Beams
    Oral

    Electron emission plays a vital role in device design for systems with pressures ranging from vacuum to atmospheric pressure. This presentation outlines the theoretical unification of field emission modeled by the Fowler-Nordheim (FN) equation and space-charge limited emission (SCLE) represented by the Child-Langmuir (CL) law at vacuum and the Mott-Gurney (MG) law with collisions [1]. We show...

  4. 616. Exact Solution for Two-Color Laser Induced Photoemission from a Biased Metal Surface
    Yi Luo (Michigan State University)

    3.2 Intense Electron and Ion Beams
    Oral

    Laser-induced electron emission is essential to the development of ultrafast electron microscopes, tabletop particle accelerators and x-ray sources, and novel quantum nanocircuits [1-3]. In particular, two-color laser induced photoemission from a metal nanotip [4] provides great flexibility for the coherent control of emitted electron distribution by using the interference effect. By solving...

    3.2 Intense Electron and Ion Beams
    Oral

    The Merlin IVA has recently completed its commissioning phase at the Technology Development Centre at AWE Aldermaston, where it has demonstrated reliable and consistent Pulsed Power operation which has enabled the demonstration of x-ray performance significantly above requirements. As part of the commissioning the opportunity was taken to take time resolved imaging of the optical emission from...

    3.2 Intense Electron and Ion Beams
    Oral

    The possible ways of improving the performance of a novel multipacting cathode is numerically investigated by using Particle-In-Cell (PIC) method. Firstly, the prototype configuration and physical model of the novel multipacting cathode are briefly introduced. Secondly, by using the self-programmed 2.5D PIC code, possible ways of improving the performance of the novel multipacting cathode are...

    Oral

    Both intense pulsed X-ray and repetitive pulsed X-rays play an important role in the investigation of various physical processes in hydrodynamic experiments.
    In order to generate intense pulses X-ray, 1.2 MV pulsed power generator and rod-pinch diode are designed and constructed at Institute of Fluid Physics, CAEP. The generator is composed of a Marx generator, an upstream oil line, a pulse...
