摘要： Apparatuses and methods for the moderation of positrons are provided herein. The apparatus may include a structure consisting of linear arrays of electrode and semiconductor structures of generally planar or cylindrical form with vacuum gaps between each element electrode. This structure may be contained within a vacuum chamber. The positron source may be positioned adjacent to the moderator structure or the electrodes may act as the positron source by pair production through bombardment of high energy photons, electrons, or neutrons. Positrons from this source may be implanted into the moderator material and drift to the moderator surfaces through the influence of the electric fields produced by the electrodes. Positrons may be emitted from the surfaces of the moderator material and may be confined by orthogonal electric and magnetic fields while they drift out from the vacuum gap between cathodes and anodes for extraction.

摘要： A method and apparatus are provided for measuring effective focus of an electron beam directed at a target. The electron beam imparts heat flux into the target to effect a target surface temperature profile thereon. A mathematical process model is used to predict an initial iteration of the temperature profile based on operating beam parameters and based on heat transfer behavioral relationships of the target. The temperature profile is optically measured and then compared with the initial iteration to obtain a residual error therebetween. The predicted temperature profile is iterated by varying the beam focus operating parameter until the residual error is less than a predetermined value for determining the effective beam focus.

摘要： An apparatus for generating and focusing electrons is provided. The apparatus has an emissive material configured to emit an electron, an electron target, and an electrical potential gradient generator configured to generate an electrical potential gradient within the emissive material. The electrical potential gradient is oriented so as to vary from positive to negative in the general direction toward the electron target. In operation, an electron emitted from the emissive materials is deflected away from the emissive material and generally toward the electron target. The apparatus may be incorporated in scientific analytical equipment such as an electron multiplier.

With such a design, the detection system can generate up to 1010 gain and maximum signal output at more than mini Ampere (mA) level. A condenser lens is configured to increase bandwidth of the detector that scan speed can be enhanced.
