    "abstract": "We report experimental evidence of electrostatic inhibition of fast\nelectrons, generated in a highly resistive material upon irradiation with an\nintense ultra-short ($10^{16} W/cm^{2}$, $100 fmsec$) laser pulse. The\nexperiment involves measurement of temporal evolution of self-generated\nmagnetic pulses using pump-probe polarimetry. A comparison is made between the\ntemporal behaviour of magnetic pulses generated with Aluminum and Glass\ntargets. It is found that in contrast to Aluminium, self-generated magnetic\npulse decays much faster in glass. This is attributed to the absence of return\nshielding currents in glass, which results in build up of electrostatic field,\nwhich in turn inhibits the movement of fast electrons. Fitting of experimental\nmeasurements using a one dimensional model, yields estimate of conductivity of\nAluminium and glass, and penetration depth of hot electrons in these materials.",
