  We are designing and fabricating two new thermionic sources of magnetized
electrons for use in the electron lens project in the Integrable Optics Test
Accelerator (IOTA) at Fermilab. These electron sources will be used for cooling
2.5 MeV protons. One source will be used to compensate for emittance growth due
to Intra Beam Scattering in experiments with weak space-charge, while the other
source will be used to research the interplay between electron cooling and
intense space charge. In this paper we present the progress made so far and the
upcoming steps for the thermionic electron sources.
