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 similar to 0.63 +/- 0.09 mu m. 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.

Automated summary

This study discussed the detailed process of preparing LiF/Ag targets using vacuum evaporation. The thickness of the fabricated targets was measured by alpha particle energy loss and estimated to be approximately 0.63 +/- 0.09 μm. The non-uniformity of the targets was within 6.50% and analyzed using a collimator. The surface morphology and elemental composition were investigated using TEM and EDX, while XPS confirmed the presence of LiF phase in the prepared targets. These targets were subsequently used for studying the 7Li(p,n) reaction at the FRENA facility in Kolkata.
