Abstract

In the present note we shall review the basic mechanisms for laser acceleration to present the related scaling laws and compare the results one expects from small (1 μ) and large (10 μ) wavelength pulses. Systematic 2D and 3D simulations were performed with the high order PICcodeALaDyn [Benedetti et al.(2008)] developedbytheuniversityofBolognatoprovide quantitative results in addition to the qualitative results of scaling laws. We shall also discuss the transport of a protons beam through an optical system. The paper consists of six sections: after this introduction, in section 2 we recall the basic features and parameters of the laser beam, in section 3 the TNSA regime is reviewed, in section 4 the RPA regime is presented, in section 5 the acceleration on under-critical target is discussed, in section 6 we discuss the transport of the optically accelerated proton bunch, in section 7 we analyze the perspectives for therapy.
