UHV ion pump power supplies

Within this folder you will find all the documentation associated with the UHV ion pump controllers.

Sometimes you will see them refered to as "EOS902" and sometimes they are called "Aurora". Aurora was designed to have one additional scaling resistor, but the high scale of picoamps was too noisy. We kept the "Aurora" pcb, but the last scaling resistor was left out, and the Aurora software never calls upon that last scaling resistor or its drive relay.

The "EOS software" folder contains a labview program for testing the units. This software is a stand-alone labview executable, but if you do not have the labview 6 runtime engine installed, you must first install it using the setup.exe file. The file has been confirmed to run on a "modern" pc running windows 7.

Note: you can plug in up to two units and use the controller address dials to look for the address of your unit. Also note, the "Address change" utility is no longer operational. We found that an HV arc on the output line could contaminate the address EEPROM memory location, so now all UHV ion pumps are programmed with a hard coded address. You can still change the address by using the bootloader program and selecting the address you want the device to be and download the file into the unit via its serial port.
