Wepresent theoretical and numerical studies of the acceleration of monoenergeticprotons in a double layer formed by the laser irradiationof an ultra-thin film. The stability of the foil isinvestigated by direct Vlasov-Maxwell simulations for different sets of laser-plasmaparameters. It is found that the foil is stable, dueto the trapping of both electrons and ions in thethin laser-plasma interaction region, where the electrons are trapped ina potential well composed of the ponderomo-tive potential of thelaser light and the electrostatic potential due to the ions,and the ions are trapped in a potential well composedof the inertial potential in an accelerated frame and theelectrostatic potential due to the electrons. The result is astable double layer, where the trapped ions are accelerated tomonoenergetic energies up to 100 MeV and beyond, which makesthem suitable for medical applications cancer treatment. The underlying physicsof trapped and untapped ions in a double layer isalso investigated theoretically and numerically.
