Multi-MeV proton source investigations in ultraintense laser-foil interactions.

چکیده
A study of the properties of multi-MeV proton emission from thin foils following ultraintense laser irradiation has been carried out. It has been shown that the protons are emitted, in a quasilaminar fashion, from a region of transverse size of the order of 100-200 microm. The imaging properties of the proton source are equivalent to those of a much smaller source located several hundred microm in front of the foil. This finding has been obtained by analyzing proton radiographs of periodically structured test objects, and is corroborated by observations of proton emission from laser-heated thick targets.

متن کاملBroad energy spectrum of laser-accelerated protons for spallation-related physics.
A beam of MeV protons, accelerated by ultraintense laser-pulse interactions with a thin target foil, is used to investigate nuclear reactions of interest for spallation physics. The laser-generated proton beam is shown (protons were measured) to have a broad energy distribution, which closely resembles the expected energy spectrum of evaporative protons (below 50 MeV) produced in GeV-proton-ind...

Tens of MeV proton beams have been generated by interactions of the VULCAN petawatt laser with foil targets and used to induce nuclear reactions in zinc and boron samples. The numbers of C, Ga, Ga, Ga, Cu, Zn, Zn, and Zn nuclei have been measured and used to determine the proton energy spectrum. It is known that sp ,nd reactions provide an important method for producing neutron sources and in t...

The generation of high-current multi-MeV protons by irradiating thin foils with short-pulse, ultrahigh intensity lasers (τ < ps, Iλ >10 8 W/cm μm) has gained great attention in the field of laser-ion acceleration due to remarkable properties of the accelerated beam and its suitability for a new type of ion source. The acceleration process takes place on the nonirradiated rear side of the foil. ...
متن کاملEffect of plasma scale length on multi MeV proton production by ultra short laser pulses
The influence of plasma density scalelength on the production of MeV protons from thin foil targets irradiated at Iλ = 5x10Wcm has been studied. With an unperturbed foil, protons with energy > 20MeV were formed in exponential energy spectrum with a temperature 2.5± 0.3 MeV. When a plasma with a scalelength of 100μm was preformed on the back of the foil the maximum proton energy was reduced to <...
