Description
A negative ion source that utilizes a porous lanthanum hexaboride surface to generate iodine ions is described. Iodine vapor supplied to the back of the lanthanum hexaboride ionizer from a reservoir percolates through to the front surface where the iodine is evaporated as ions. The peak ion current obtained 2, 2.1 mA at an ion energy of 0.3 keV, leads to a density napprox. =1010 cm-3
