Title: Un: PES experiment control program

Technical Report ·
DOI:https://doi.org/10.2172/6985090· OSTI ID:6985090

This document is a user's manual for the data acquisition program Un. Un controls data acquisition equipment and organizes and plots data for spectroscopy experiments and is installed at a number of beamlines at the VUV ring at the NSLS. This document deals specifically with the installation at beamline U14A, although most aspects will also apply to other beamline versions. Then when invoking the program the n' is usually replaced by the beamline number, e.g., u14, u5. Un is written in the C programming language under the VENIX operating system, an implementation of UNIX which runs on the IBM PC. Control of the monochromator and electron analyzer, as well as simple data manipulation, is provided through an interactive language' of two letter commands. You should be able to use Un immediately by skipping to the section Starting the Program.' If, however, you encounter problems in getting the program to run, the following section, Un and UNIX' will be helpful. In any case, it is advisable to read this section eventually if you are not familiar with the UNIX operating system.
