We report on the development and testing of an intense lithium ion source and injector for an ion induction accelerator designed for warm, dense matter target heating experiments. The source is a 10.9-cm diameter aluminosilicate emitter on a porous tungsten substrate. For an injector voltage pulse of 120 kV, pulse duration of 1.0-μs FWHM, and an operating temperature of 1250°C, the source emits 35 mA of Li^{+} ions. The results follow experimental studies with much smaller sources. The key challenges included beam quality, source lifetime, and heat management.
