Resonance Absorption in a Laser-Produced Plasma Generated by a High-Intensity Ultrashort Pulse
Autor: R. Sauerbrey, B. van Wonterghem, J. Bergmann, U. Teubner, F. P. Schäfer
Publikováno v: Shortwavelength V: Physics with Intense Laser Pulses.
Plasmas were generated by 400 fs Kr F laser puises at intensities of ~ 1017 W cm‒2 on aluminum and carbon targets. Reflectivity and x-ray emission were measured as a function of laser polarization, angle of incidence, and intensity. For the same ab

Publikováno v: Shortwavelength V: Physics with Intense Laser Pulses.
The development of ultrabright lasers is progressing rapidly particularly in the direction of table-top-terawatt systems operating at high pulse repetition rate with relatively low pulse energy. The highest pulse energies and highest absolute powers

Autor: W. Gasteyer, B. Wagner, T. Kettner, H. G. Andresen, J. Ahrens, E. Reichert, Werner Heil, D. Conrath, W. Hartmann, L. Koch, H.-J. Gessinger, H. Kessler, F. P. Schäfer, J. Jethwa
Publikováno v: Nuclear Instruments & Methods in Physics Research Section A-Accelerators Spectrometers Detectors and Associated Equipment
The source described is based on photoemission of electrons from 100-GaAs0.62P0.38 activated to negative electron affinity. It is built to inject a beam of polarized electrons into the 350 MeV linear accelerator in Mainz. It is capable of delivering

Publikováno v: Nuclear Physics B
In scattering polarized electrons (P1 = 44% by 9Be at an energy of 300 MeV at angles 115°⩽ϑ⩽145° a parity violating asymmetry of Acorr = (−3.5 ± 0.7 ± 0.2) × 10−6 was measured. After correction for finite electron polarization and backg
