Measurement of the Target Current and EMP on Terawatt Laser System PALS

Popis výsledku v původním jazyce

The experiments are performed at high-power photodissociation iodine laser (1.315 ?m, E=<1 kJ, t = 400 ps, I=6x10E16 W/cm2) at thePALSResearchCenterinPrague.During interaction of a focused intensive laser pulse with a solid target fast electrons are escaping and the target becomes charged. This charge can be neutralized by current flowing throw the target holder to the ground. The current with large time derivation, which is related to the laser pulse shape and to the inductance of the grounding circuit, generates a electromagnetic pulse in radio or microwave frequency band. Because the interaction chamber is usually equipped by a glass windows, insulators for galvanic separation, cables and so on, the electromagnetic pulse (EMP) passes out from the interaction chamber. At high-power laser facilities the EMP disturbs electrical signals, causes incorrect work of diagnostics, computers or control equipment. The study of target currents and EMP is important for design of all diagnostic in
