    "abstract": "We present a clear signature of the Schottky effect in a RF photoinjector\nusing photons with energy lower than the Mg cathode work function. This\nsignature is manifested by the shift in the RF phase angle for the onset of the\ndetection of photoelectrons via single-photon absorption and allows for a\nreasonable estimate of the field enhancement factor. This is a viable method to\ngenerate an electron beam with very low thermal emittance and thus, a high\nbrightness beam.",
