  • Beschreibung: A novel proton imaging technique was applied which allows a continuous temporal record of electric fields within a time window of several nanoseconds. This “proton streak deflectometry” was used to investigate transient electric fields of intense (∼1017W∕cm2) laser irradiated foils. We found out that these fields with an absolute peak of up to 108V∕m extend over millimeter lateral extension and decay at nanosecond duration. Hence, they last much longer than the (approximately picosecond) laser excitation and extend much beyond the laser irradiation focus.
