Paper Abstract

Pulsed hard X-ray was radiated from the electrode at positive high electric potential, when a laser plasma was created on the grounded electrode positioned a few cm apart from the positively charged electrode. We considered the possibility that electrons extracted from the laser plasma were accelerated and coffided with positively charged electrode, radiating the pulsed X-ray. The dependence of dosage and pulse width of the X-ray on laser pulse energy and on electrode spacing was investigated, and some evidence to describe the X-ray radiation mechanism was obtained.
