The photocathode R&D program at Lawrence Berkeley National Laboratory is presented, including the status of the lab and experimental results. We will also present experimental result obtained at Brescia Italy and theoretical work on predicting minimum thermal emittance from metal cathodes and emittance growth due to stochastic Coulomb interaction.
