Abstract :
Summary form only given. LSP simulations for a short pulse (0.3 ps) high intensity laser (a0=2) interacting with an isolated 20-mum diameter wire target have predicted that the energetic electrons have a maximum energy of 2 MeV with an average temperature of 0.15 MeV. Strong self-generated magnetic fields (10´s of MG) should be produced by the current flowing through the wire. It has been proposed that the fields produced at the focal spot and flowing through the wire can be detected using proton deflectometry. We have studied the proton dynamics for current flowing in the wire and show that the deflection observed in the radiochromic film detectors can be related to the field structure around the wire
