摘要： An apparatus for the indirect cooling of a silicon drift detector (SDD) includes an enclosure with a vacuum maintained therein, at least one SDD module that generates substantially no heat positioned within the enclosure, a cooling engine positioned remote from the SDD module within the enclosure for cooling the SDD module, whereby heat is generated by the cooling engine, a thermal conduction device comprising a first end thermally coupled to the cooling engine and a second end thermally coupled to the SDD module and a heat removal device thermally coupled to the cooling engine. The cooling engine indirectly cools the SDD module by transferring thermal energy through the thermal conduction device from the SDD module and the heat removal device dissipates the heat generated by the cooling engine to the environment surrounding the enclosure. A method for indirectly cooling a radiation detector is also provided.

摘要： A method of measuring the transfer function of an X-ray optical component over a wide range of X-ray energies, which includes the steps of: using an X-ray optical component between an X-ray source and a scattering target to obtain a first scatter spectrum; obtaining a second scatter spectrum from the same or a similar target without the X-ray optical component between the X-ray source and the scattering target; and calculating the transfer function by the ratio of the first scatter spectrum to the second scatter spectrum. The method can be used to improve the accuracy of X-ray quantitative methods in an apparatus where an X-ray optical component is used between the X-ray source and the specimen to be investigated by utilizing the method described above.

摘要： A pass-through shutter mechanism enables the semiconductor crystal of an energy dispersive x-ray detector to extend beyond the shutter mechanism for analysis, adjacent to the sample, achieving optimum solid angle collection efficiency. The shutter mechanism provides optimum protection of the semiconductor detector crystal from high energy x-ray or secondary electron events produced in the chambers of electron microscopes, microprobes, x-ray spectrometers, etc.

摘要： A radiation detector having an evacuated envelope, a radiation detector on a cold finger support in the evacuated space, a closed cycle gas cooling system to cool the cold finger to provide cryogenic operation of the radiation detector, and a getter in the evacuated space to maintain an evacuated condition. The evacuated envelope includes a radiation window. The radiation detector is preferably an X-ray detector employed in an energy dispersive spectrometry system. The evacuated space is preferably held at a pressure of less than about 1 mTorr to achieve molecular flow of remaining gas molecules, minimizing parasitic heat input. The closed cycle gas cooling system employs compressed refrigerant, which is precooled in a counterflow heat exchanger and allowed to expand in proximity to the cold finger, thus absorbing heat and maintaining cryogenic temperatures. A getter material, preferably activated carbon, is provided to absorb gasses and maintain the low pressure during operation. A vibration effect attenuation system is provided to reduce effect of cooler induced reduction in detector resolution.
