Invited
The target laboratory in IFIN-HH was developed to respond to the necessity of thin films ranging from tens of nanometers to a few micrometers, which are used for nuclear physics experiments at our 9MV Tandem accelerator. In order to fulfill the specific requirements, our laboratory is endowed with high quality equipment for evaporation-condensation, cold rolling, electron gun and pulsed laser...

An evaporated metal foil target is often produced on a layer of water- soluble parting agent previously applied to a massive substrate. The foil is then floated onto a water surface by immersing the substrate into a water bath. and is picked up later if the foil survives. During the foil's release, a significant fraction of the dissolved parting agent remains close to the floating foil, as...

Oral
In most of nuclear physics experiments conducted at iThemba LABS, a particle beam from the separated sector cyclotron (SSC) impinged upon a target material, either self-supporting or on a backing. The methods currently used to manufacture these target materials include vacuum evaporation system with various heating sources, one using electrons and the other using resistive heating. Mechanical...

A new method was developed to produce enriched Sulfur targets. This was made possible by inserting sulfur in-between two 0.5 mm Mylar foils (C10H8O4). The aim is to ensure that sulfur targets reduces by no more than 50% of the initial thickness within 24 hours under the equivalent of 10 J of integrated energy deposition by a proton beam. There is no loss of enriched material while making the...
