Computer Control of the Vacuum Ultraviolet Reflectometer
Our group is researching broadband aluminum mirrors for a space-based telescope with emphasis on the vacuum ultraviolet (VUV) part of the electromagnetic spectrum. Since air is highly absorbing at VUV wavelengths, measurements need to be made under vacuum, and therefore via computer. I will discuss two additions to the data collection program: improved multithreaded communication with the device controllers in the system, and automated theta-2theta reflection measurements. For the former I used the C# lock function to resolve collision issues with multiple threads attempting to access the same non-multithreaded controller. As for the latter, the development of theta-2theta functionality is ongoing and must coordinate the movement of the sample and the mirror, as well as account for variation in the plasma source we use to generate VUV light.
