Description

Self-supporting beryllium (​9​Be) targets were produced by mechanical rolling method in which a double pack technique was implemented. Targets were used for the investigation of the low-lying excitation energy region in ​9​Be through the ​9​Be(​3​He,t)​9​B reaction at the K600 spectrometer, at iThemba LABS facility. Beryllium is a semimetal in nature and this makes it hard to deform by rolling or vacuum evaporate as a self-supporting target. Therefore heat treatment was needed to avoid brittleness and breakage of the material during rolling process. A description is given on how beryllium targets were manufactured.
