The successful operation of a GaAs‐based polarized electron source utilizing a DC high voltage gun for the SLC program at SLAC has raised the prospects for a similar source for next generation linear colliders (NGLC). A major challenge in meeting the NGLC requirements is to produce ≳1012 electrons per macrobunch from the cathode. The physics issues that are involved in limiting charge extraction from a GaAs‐type cathode and the prospects of realizing a NGLC polarized electron source based on an SLC‐type gun will be discussed.
