JEOL 8200 Electron Probe
JEOL 5800LV Scanning Electron Microscope
Electron Probe Tutorial and How-To Guides
These guides were compiled by Laboratory Manager Mike Spilde and presented as IOM seminars during 2007 and 2008. They cover a great many detailed topics in use of the electron microprobe and its various systems, and are strongly recommended for users of every experience level.

Retrieving data and image files from the JEOL 8200 computer via secure FTP
By simply downloading a secure FTP client to your own computer, you can have access to your files on the probe at any time. You don't have to be sitting at the probe to transfer data. In addition, this avoids filling the EPS common drive with clutter (and thus Mike won't have to nag you to keep the Probe Lab folder clean).
FTP clients for data download
Windows users, download the secure FTP client contained in the CIRT "SSH" package, by following this link. Right click and select "Save Target As..." and copy the file ssh.exe to your hard drive. Then launch it and follow the prompts to install the program on your machine. The default target for this FTP program is to UNM's main site; follow the instructions in the following paragraphs to add a "profile" that accesses the electron probe computer.
Using SSH on Windows machines
After installation, run SSH. It will open a dialog trying to connect to ftp.unm.edu. Replace "ftp.unm.edu" in the "host name" panel with "184.108.40.206" (without the quote marks, of course). You could also use "epsprobe.unm.edu"; but on those occasions when UNM's domain-name servers are down (it happens) this will fail. The numeric IP address will always work, provided the probe computer is on the network, because no "translation" from a textual to a numeric internet address is required.
Enter your microprobe computer account name in the "user name" panel. Leave everything else as is and press the Connect button. A new dialog will pop up asking for your password; enter your probe account password. Assuming the network is functioning properly, you will now see a two-pane, Windows-explorer-like interface showing your computer on the left and your probe account's home directory and subdirectories on the right. Now go up to the File menu in the upper left corner and select "Save Settings". This will save all settings so that the next time you launch SSH, it will default to your probe computer account and ask only for your password.
Moving files is now a matter of simply dragging and dropping from one panel to the other. Browse in the left-hand panel to your desired destination folder on your local computer; then browse through your probe account's folders to find the files you want, and simply drag them over. When you're done, just exit the program as you would any other Windows program.
Using Mac programs
If using Fetch, enter epsprobe.unm.edu or 220.127.116.11 as the host, your user name, and the probe password, and click OK. (You can set this up as a shortcut by using the shortcut pulldown menu). Then just highlight the files you want to download and click on "get files". Fugu works in a similar way. Alternatively, you can use the Mac terminal program. Enter ftp epsprobe.unm.edu or ftp 18.104.22.168, then type your username and the probe password at the prompts. It will put you into your own user directory and you can get a listing using the ls command. Use the cd command to whichever directories you want and use get to get the files, using * as the wildcard character if you want.
