AbstractAbstract
[en] Titanium (Ti) is a strong material with low density and high strength. In its natural form it is a lustrous metal with silverish white color. Its melting point is 1668 °C but when Ti is heated above 430 °C, it loses its strength. The targets prepared were to be used in a nuclear fusion evaporation experiment, in which evaporation residues were detected using MWPCs kept at forward angles. For the evaporation residues formed to reach the detector, it was required that energy loss of the residues is minimum in the targets prepared. So, the optimal thickness for the self-sustaining targets is around 500 μg/cm2. The self-supporting thin films of Ti were prepared in the ultra-high (UH) vacuum chamber at Inter University Accelerator Centre (IUAC), New Delhi. Vast literature is available for the preparation of self-supporting targets of 48Ti. But all of them are based on either the substrate heating or using various parting agents that required dry stripping to be performed. With the limited material, around 6 thin self-supporting targets of 48Ti of various thickness (318 μg/cm2 to 548 μg/cm2) were fabricated using electron beam evaporation method. Various constraints faced during the trials and measures taken to overcome and finally obtain the desired targets is discussed in detail
