An alloy liquid metal ion source for lithium
An alloy liquid metal ion source for lithium
Bischoff, L.; Akhmadaliev, C.
The presented alloy liquid metal ion source enables a long term stable emission of Li ions. By using a Ga35Bi60Li5 alloy the difficulties in handling chemically very active lithium as a source material could be overcome. The mass spectrum and the energy spread of the certain ion species are presented and discussed. For lithium a FWHM of the energy distribution of about 2 eV at an emission current of about 1 µA was found as it is predicted by the theory due to the m1/3 dependence of the energy spread on mass of the projectile ion.
