Annular shaped laser-accelerated proton beams
Since their discovery in 1999 [1] the topic of laseraccelerated ions has attracted high attention both in the field of plasma-physics and in the accelerator community. In a typical laser-accelerated ion scheme a thin metal foil is irradiated by an ultra-intense chirped pulse amplified laser beam which leads to the generation of relativistic electrons. These electrons are accelerated through the...
متن کامل3-D reconstruction of a laser accelerated proton beam using micro-structured target foils and radiochromic film detectors∗
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 کاملPatient-Specific QA of Spot-Scanning Proton Beams using Radiochromic Film.
Radiochromic film for spot-scanning QA provides high spatial resolution and efficiency gains from one-shot irradiation for multiple depths. However, calibration can be a tedious procedure which may limit widespread use. Moreover, since there may be an energy dependence, which manifests as a depth dependence, this may require additional measurements for each patient. We present a one-scan protoc...
متن کاملLaser-Accelerated Proton Beams as Diagnostics for Cultural Heritage
This paper introduces the first use of laser-generated proton beams as diagnostic for materials of interest in the domain of Cultural Heritage. Using laser-accelerated protons, as generated by interaction of a high-power short-pulse laser with a solid target, we can produce proton-induced X-ray emission spectroscopies (PIXE). By correctly tuning the proton flux on the sample, we are able to per...
متن کاملTransport of laser-accelerated proton beams with pulsed high-field solenoids
The interaction between an ultra-intense laser pulse (I > 10 W/cm) and a thin target foil leads to an acceleration of protons up to kinetic energies of several tens of MeV. In the short acceleration time of a few picoseconds up to 10 protons and ions are accelerated. Well-defined, smooth beams with transverse emittances more than hundred times smaller than in conventional accelerators are obser...
