    "abstract": "Future colliders that require low-emittance highly-polarized electron beams\nare the main motivation for developing a polarized rf gun. However there are\nboth technical and physics issues in generating highly polarized electron beams\nusing rf guns that remain to be resolved. The PWT design offers promising\nfeatures that may facilitate solutions to technical problems such as field\nemission and poor vacuum. Physics issues such as emission time now seem to be\nsatisfactorily resolved. Other issues, such as the effect of magnetic fields at\nthe cathode-both those associated with the rf field and those imposed by\nschemes to produce flat beams-are still open questions. Potential solution of\nremaining problems will be discussed in the context of the PWT design.",
