The high efficiency preparation method of isotope targets with low evaporation temperature by a multi-point evaporation source

High efficiency multi-point evaporation source is very preponderant to prepare deposits of materials with low evaporation temperature. Using this technique materials such as Zn, Cd, Mg, Se, Yb, Sb, Te, etc. can be deposited with the average recovery (K value) of 75% and K value of the average deposition efficiency is about 850 μg/cm2/mg.
