Abstract

The observations of proton emission from wire targets, performed at the Rutherford Appleton Laboratory were reported. The experiments were carried out by using the Chirped Pulsed Amplification beam line of VULCAN laser facility. It was observed that the presence of objects in the vicinity of the interaction had an effect on the angular emission pattern of protons from the primary targets. The results show that the objects in close proximity of the main target can become sheath formation on the secondary object.
