The  Laser-Plasma Summer School -LAPLASS- is a specialized international event organized every year by the Spanish Center for Pulsed Lasers -CLPU- and the CLPU Laser-Plasma Chair  [1]at the University of Salamanca. Laser-driven plasma is the primary subject of investigation in modern high-power laser facilities. The Centro de Láseres Pulsados (CLPU) is one of the most representative facilities in this area operating a PW level system working at 1-10 Hz, VEGA. The fourth edition, titled 'Experimental methods in High-Intensity Laser-Plasma processes', will be supported by the European Project 'IMPULSE [2]', in which the CLPU participates.
