In this paper, we discuss using laser plasma as a source of high-energy ions for the purposes of hadron (proton) therapy. Hadron therapy (HT) is a modern, high-precision form of radiation therapy that uses protons to irradiate diseased tissue. HT has received the greatest use for the fight against cancer. The high accuracy of cancer cell damage, together with the gentlest impact on healthy organs and normal tissues, the absence or mild side effects, make proton therapy indispensable where the tumour is located next to the vital organs, in paediatrics, where the anatomical location of the tumour makes it impossible for surgical removal and use of photon therapy will place the patient at an unacceptable risk. In our work we present the results of mathematical modelling of laser pulse with substance. Computer modelling gives the chance of selection of parameters of a laser pulse and target, for more exact focusing of a pulse and obtaining the set energy of ions.
