The detailed investigation, performed using a 'standard' second order accurate PIC code, of the highly nonlinear physics involved in the laser-matter interaction is in general computationally expensive in terms of grid size, particle number and number of simulation steps. The use of high order integration schemes (in space and time) should reduce, for a fixed accuracy, the computation cost of the simulations. In this contribution we present our efforts in developing and benchmarking high order PIC schemes. Particular attention will be devoted to the implementation of charge preserving algorithms. Consolidated results of this numerical activity have been implemented and tested on the relativistic, parallelized PIC code ALaDyn (Acceleration by LAser and DYNamics of charged particles) developed at the University of Bologna in the framework of the INFN experiment 'PLASMONX' (PLASma acceleration and MONochromatic X-ray production). In this contribution we present the main features of the ALaDyn code together with some applications of interest for the PLASMONX experiment.
