The preparation of LiF target for reactions involving 7Li target

The preparation of LiF targets on a self-supporting Ag backing (LiF/Ag) was discussed in detail using the vacuum evaporation process. The fabricated LiF targets were analyzed and efficiently characterized, with the target thickness measured by the energy loss of alpha particles through the target. The estimated thickness of LiF was ∼0.63±0.09μm. The non-uniformity of the targets was thoroughly checked with the help of a collimator, and the non-uniformity was within 6.50 %. The surface morphology and elemental composition were investigated using transmission electron microscope (TEM) and the Energy dispersive X-ray spectroscopy (EDX). Further x-ray photoelectron spectroscopy (XPS) was performed on the prepared targets and the presence of LiF phase has been confirmed by XPS. The targets were used to study the 7Li(p,n) reaction at the FRENA facility in Kolkata.
