  We have been studying an S-band Cs2Te-Cathode RF Gun with 1.6 cells. The new gun cavity reported in this poster has new RF tuners, which are compact and, therefore, can be attached even on the half-cell. RF balance between the full- and half-cells is adjustable by using the tuners on both cells. Compared to the existing cavity, a Helicoflex seal for half-cell adjustment is not needed for new one. This structure is expected to have advantages for gun machining, for Q factor of the cavity, and for reduction of dark current from the RF gun. The cathode is made by evaporation on a Mo plug, and the plug is attached by a load lock system. We report status of the gun development.
