Results from the Ucla/fnpl Underdense Plasma Lens Experiment
A gaussian underdense plasma lens with peak density 5 x 1012 cm−3 and a full width half maximum (FWHM) length of 2.2 cm has been used to focus a relativistic electron beam. This plasma lens is equivalent in strength to a quadrupole magnet with a 150 T/m field gradient. The lens focused a 15 MeV, 16 nC electron beam with initial dimensions σx,y ≈ 650 μm and σz ≈ 6.5 mm onto an optical transition...
متن کاملUCLA/FNPL Underdense Plasma Lens Experiment: Results and Analysis
Focusing of a 15 MeV, 16 nC electron bunch by a gaussian underdense plasma lens operated just beyond the threshold of the underdense condition has been demonstrated. The strong 1.9 cm focal length plasma lens focused both transverse directions simultaneously and reduced the minimum area of the beam spot by a factor of 23. Analysis of the beam envelope evolution observed near the beam waist show...
متن کاملUnderdense Plasma Lens Experiment at the Ucla Neptune Laboratory
An underdense plasma-lens experiment is planned at the UCLA Neptune Laboratory. For this experiment, a LaB6based discharge plasma source was developed and tested. Test results of the plasma source show that it can provide satisfactory argon plasma parameters for underdense plasma lens experiments, i.e., a density in low 10 cm 3 range and a thickness of a few cm. In the plasma chamber a YAG slab...
متن کاملPlasma Source Test and Simulation Results for the Underdense Plasma Lens Experiment at the UCLA Neptune Laboratory
The planned plasma lens experiment at the UCLA Neptune Laboratory is described. In the experiment, electron beams with an energy of 16 MeV, a charge of 4 nC, and a pulse duration of 30 ps [full-width at half-maximum (FWHM)] are designed to be produced from the 1.625-cell photoinjector radio-frequency gun ( = 2 856 GHz) and PWT linac in the Neptune. The generated beams are passed through a thin ...
متن کاملTest Results of the Plasma Source for Underdense Plasma Lens Experiments at the UCLA Neptune Lab
A plasma source was developed at UCLA for planned underdense plasma lens experiments, where the plasma density is less than the electron beam density. The argon plasma, produced by a discharge between a LaB6 cathode at 1330 C and a tantalum anode, is con ned by a solenoidal magnetic eld and ows transversely across the electron beam path. Extensive test of the plasma source is under way for vari...
