Spectroscopic Observation of Fast Ions from Laser-Produced Plasmas.

Abstract

Using a time-of-flight spectroscopic technique, measurements were made of the ion energy distributions of very fast ions and thermal ions produced when a 7-15 J, 100 psec Nd:glass laser pulse (1.06 micrometer) strikes a (CH2)n slab target. Ion energies greater than 0.5 MeV have been observed for the first time with this technique of measurement. A simultaneous comparison is made between the signal of an ion charge collector placed 30 cm from the target and the intensity of the C VI 3434 A ion line at 1 cm from the target. (Author)
