Abstract:
1. An apparatus for moderation of positrons, the apparatus comprising: a vacuum chamber; at least one cathode structure positioned within the vacuum chamber; a moderator material attached to at least a portion of the at least one cathode structure, wherein the moderator material is configured to receive positrons from a positron source; at least one anode positioned within the vacuum chamber and spaced apart from the at least one cathode structure and moderator material so as to define a vacuum gap between the moderator material and the at least one anode; and a voltage source connected to the at least one cathode structure and the at least one anode, wherein the voltage source is configured to apply a positive potential to the at least one cathode structure and a negative potential to the at least one anode to create an electric field that is configured to cause the positrons received by the moderator material to drift toward a surface of the moderator material and into a vacuum gap.
