Session 12: Novel Research and Applications (and concluding discussion)

We present the results of experimental observation of emission from single diamond field emitter tips when
triggered by an ultra-short laser pulse. Diamond field emitter array (DFEA) cathodes were originally proposed
for applications that require large current densities. DFEAs represent periodic arrays of diamond pyramids with
micron-size dimensions and tips with diameters of the order of tens...

Session 12: Novel Research and Applications (and concluding discussion)

Recent research on photocathode materials has focused on the achievement of very low intrinsic emittance. Future research goals require the setting up of a measurement apparatus capable of measuring very low mean transverse energy values, as low as 1 meV. Furthermore, cooling the photocathode to cryogenic temperature is also a way to reduce the intrinsic emittance and to control and study the...
