 note = {Future high energy accelerators require polarized electron sources that can generate high bunch  charge and/or high density electron beam with low emittance. Various superlattice photocathodes  and a high voltage load-lock DC gun have been developed at Nagoya University for this purpose.  Using a GaAs-GaAsP strained superlattice photocathode, the bunch charge of 8nC was extracted in a 1.6ns bunch with a 20 mm diameter, and that of 3.3pC in ∼30ps bunch with 1.2mm diameter.},
