Side-entry differentially pumped environmental chamber for the AE1-EM7 HVEM

Proceedings, annual meeting, Electron Microscopy Society of America, 1986
A side-entry differentially pumped environmental chamber (SEDPEC) has been designed and constructed for the AEI-EM7 high-voltage electron microscope (HVEM). The SEDPEC has been tested in the same way as previous chambers for the HVEM. In contrast to the lengthy procedures necessary to install previous environmental chambers in the HVEM, the SEDPEC can ...

New Design for a Differentially Pumped Hydration Chamber for a Siemens IA

Proceedings, annual meeting, Electron Microscopy Society of America, 1971
Electron microscopy and diffraction of biological materials in the hydrated state requires the construction of a chamber in which the water vapor pressure can be maintained at saturation for a given specimen temperature, while minimally affecting the normal vacuum of the remainder of the microscope column.

Influence Boundary Layer In The Differentially Pumped Chamber

2017
The goal of this thesis is the analysis of a gas flowing through the drain channels within the apertures of differentially pumped chamber of the Environmental Scanning Electron Microscope (ESEM). This thesis contains a verification of current simulation results of gas flow within the differentially pumped chamber published by D.

The Impact Of Critical Flow In Differentially Pumped Chamber

2017
Environmentální rastrovací elektronový mikroskop (EREM), který je konstruován pro vysoký tlak plynů v komoře vzorku namísto vakua, umožňuje studovat vzorky obsahující vodu nebo živé biologické vzorky bez nutnosti jejich speciální úpravy. To z důvodu, že mezi komoru vzorku a tubus je vložena diferenciálně čerpaná komora.

Comparison of Results Optained Using Monte Carlo and Ansys Fluent in Analysis Differentially Pumped Chamber

2016
The goal of this thesis is the analysis of a gas flow running through the drain channels within the apertures of differentially pumped chamber of the Environmental Scanning Electron Microscope (ESEM). This thesis contains a verification of current simulation results of gas flow within the differentially pumped chamber published by D.

Design Of The Shape Of The Experimental Chamber For The Analysis Of The Pressure Layout In The Differential Pumped Chamber

2018
This article is based on a study of Dr. Danilatos, where pumping of the differential pumped chamber is solved using the Monte Carlo statistical method. Similar results were obtained using the Ansys Fluent system. Theoretical computations as Dr. Danilatos and comparative studies are performed on theoretical shape.
