Abstract:
1. A gas field ion source for a charged particle beam device having a charged particle beam column, comprising: an emitter unit; a cooling unit; a thermal conductivity unit for thermal conductivity from the cooling unit to the emitter unit, wherein the thermal conductivity unit includes a flexible wire, strip or braid extended between a protruding portion of the cooling unit and a protruding portion of the emitter unit and is adapted for reducing vibration transfer from the cooling unit to the emitter unit, the protruding portion of the cooling unit and the protruding portion of the emitter unit being overlapped in a first direction, and wherein the flexible wire, strip or braid of the thermal conductivity unit extends in a plane perpendicular to the first direction; and an emitter unit support for connecting the emitter unit with a portion of the charged particle beam column, wherein the emitter unit is indirectly connected to the cooling unit.
