Electron Microprobe Operation BASIC INSTRUCTIONS FOR USING THE JEOL ELECTRON MICROPROBE J E Patterson 20/9/ This document is a simplified manual for the operation and setup of the JEOL electron microprobe.
It is not a replacement for the hardware and software documentation. The electron microprobe essentially consists of an electron column and several x-ray spectrometers, which can be WD and/or energy-dispersive (ED) spectrometers. The electron column consists of an electron gun and an electromagnetic lens system (see Fig.2).
The electron gun acts as a source of electrons. If the day is either Monday or Friday, fill the dewar and record this fact in the log book. Turn on the Mac G3 and MAC IIvx.
Press the arrow key in the upper right corner of each keyboard. Check the spectrometer and stage positions. The spectrometers should be located at approximately and the stage at X=, Y= Vermiculite sample (mean crystal dimensions ×× mm) was analysed chemically, using a wavelength-dispersive ARL-SEMQ electron microprobe (operating conditions: 15 kV accelerating voltage, 15 nA sample current and enlarged spot size of about 8 μm to reduce the damage of the mineral; analyses and data reductions were performed using Cited by: ELECTRON MICROBEAM - EMPA electron microprobe; wavelength dispersive spectrometers ARL SEMQ with Advanced Microbeam software.

About the Lab. The University of Arizona Electron Microprobe Laboratory began operation in with an ARL SEMQ electron microprobe and has been under the overall supervision of Professor Michael J.
Drake since that time. Thomas Teska provided day-to-day management of the facility from until his retirement in An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials.
It is essentially a hybrid instrument combining the capabilities of both the scanning electron microscope (SEM) and an x-ray fluorescence spectrometer (XRF), with the added features of fine-spot focusing (~ 1File Size: KB. The main peaks in the cm- region are due to absorption by tetrahedral bonds.

All manuals for Vendor supplied third-party items shall be provided.The electron microprobe, also known as the electron probe micro-analyzer (EPMA), uses X-ray spectrometry to identify and measure concentration of elements in microscopic volumes of the specimen.
In the EPMA, a finely focused electron beam interacts with the sample to generate back-scattered electrons (BSE), secondary electrons.Secondary Electron (SE) and Back-Scattered Electron (BSE) detectors Probe for EPMA software for state-of-the-art quantification and automated analyses.
The primary purpose of the electron microprobe is to generate quantitative and qualitative chemical analyses of any material that is stable under the electron beam and under high vacuum.
