  1. 17. Parametric instabilities, electron injection and acceleration from relativistic laser interaction with solid targets
    Prof. Andrei Savel'ev (Lomonosov Moscow State University)
    30.01.20, 10:30
    Efficient direct electron acceleration in the plasma channel with injection through the breaking of plasma waves generated by parametric instabilities was demonstrated experimentally and reproduced in the 2D3V PIC simulations. The electron bunch was produced using the specific plasma profile containing arbitrary sharp, ∼0.5λ, gradient at the vicinity of 0.1–0.5 critical density and a long tail...

  2. 32. Optically tunable proton acceleration in femtosecond ultraintense laser-foil interaction
    Dr. Wenqing Wei (Xi'an Jiaotong University)
    30.01.20, 10:55
    The rapid development, especially in the intensity and temporal contrast of ultraintense short-pulse lasers and the achievable technology of the nanometer materials have enabled new regimes of relativistic laser-plasma-interaction research and applications, such as laser-driven ion acceleration based on novel mechanisms, warm dense matter generation. A critical aspect of these is the initial...

  3. 41. Development and plasma physical investigation of a plasma window for the generation of high pressure differences
    Bernhard F. Bohlender (Goethe University Frankfurt, Institute for Applied Physics)
    30.01.20, 11:20
    A plasma window (PW) is a device for separating two areas of different pressures while letting particle beams pass with little to no loss. It has been introduced by A. Hershcovitch. In the course of this talk, the properties of a PW with apertures of 3.3 and 5.0mm will be presented which was investigated during my PhD thesis. As working gas, a 98%Ar-2%H$_2$ mixture has been used due to...

  4. 27. Setup and investigation of a plasma window with optimized apertures for intense particle beam transmission to high pressure targets
    Andre Michel (IAP, Goethe University Frankfurt)
    30.01.20, 11:45
    A plasma window (PW) provides a membrane free particle beam transmission while separating low pressure areas such as accelerator vacuums from high pressurized environments. It offers advantages over conventional low pressure interfaces such as higher operation times and shorter length scales. At IAP Frankfurt, a PW was successfully developed and investigated in terms of its pressure separation...
