Title
(EN) SAMPLE HOLDER FOR ELECTRON MICROSCOPY
(FR) PORTE-ÉCHANTILLON POUR MICROSCOPIE ÉLECTRONIQUE
Abstract
(EN)
The apparatus is for use with an electron microscope, a sample, a source of high pressure gas and a vacuum pump system. The apparatus includes a holder part a body part and a Joule-Thomson refrigerator. The holder part is adapted to receive the sample and adapted to present the sample to the microscope for inspection in use. The body part defines a cavity, the cavity being evacuated by the vacuum pump system for use. The refrigerator is disposed within the cavity and thermally-coupled to the holder part, the refrigerator being coupled in use to the source of high pressure gas to maintain the sample at about a predetermined temperature.

L'invention porte sur un appareil destiné à être utilisé avec un microscope électronique, un échantillon, une source de gaz haute pression et un système de pompe à vide. L'appareil comprend une partie support, une partie corps et un réfrigérateur Joule-Thomson. La partie support est conçue pour recevoir l'échantillon et conçue pour présenter l'échantillon au microscope pour son inspection lors de l'utilisation. La partie corps définit une cavité, la cavité étant évacuée par le système de pompe à vide pour l'utilisation. Le réfrigérateur est disposé à l'intérieur de la cavité et couplé thermiquement à la partie support, le réfrigérateur étant couplé, lors de l'utilisation, à la source de gaz haute pression pour maintenir l'échantillon à environ une température prédéterminée.
