Highly charged Ta ions produced by the photodissociation iodine laser with subnanosecond pulses

Abstract

The results of the generation of tantalum ions with a charge state of 46+ are reported. Iodine laser pulses of about 15 J energy and 350 ps in duration were used for a Ta plasma production. Multiply charged ions were recorded by the diagnostic techniques based on the time-of-flight method in the distance of approximately 200 cm. The plasma temperature estimated from the ion measurements was found to be about 1750 eV.
