To provide:


The depth-dose curve, the depth-charge curve, the number-transmission curve, etc. of plane-parallel electron beams mainly in the energy region from 0.1 to 20 MeV


The values of the continuous slowing-down approximation range, the extrapolated range, the average reach (originally proposed as the average depth of electron penetration), the average penetration depth (also called projected range), and number- and energy-reflection ratios (at saturation)


A good insight into the general trends of the interactions of fast electrons with thick layers of matter (effectively semi-infinite media or slab absorbers)

How to Use



To use EMID, you need modern browser (Internet Explorer, Mozilla Firefox, Opera, Safari, Google Chrome, ...).
Click here to get advanced important information.


Select one of Modes on the left. The program for the selected mode opens in a new window. You can open up to three mode windows at the same time, each from a different group. In addition, you can open three Help pages from those mode windows and one page from the five menu items at the top of the main page (a total of eight windows) simultaneously.


All your input and output data are localized on your computer. Thus the protection of the information about your usage is guaranteed.


After loading the necessary programs, you can work offline.


Introduction is provided in each window. Clicking "Help" or "How to Get Results" in each window gives you instructions.
