Diagnostic Data Acquisition for the Laser Beam at FNPL

The Aø department at the Fermi *NICADD photoinjector laboratory (FNPL) is a research and development facility. The facility is open to research from individually proposed projects in the area of Accelerator Science [5]. Research done at this facility depends on the beam line produced at the Aø laser room. In order to guarantee that the beam that reaches the user experimental area carries with it stable properties, part of the beam is sent to a diagnostics table to be analyzed. Two instruments are set up to characterize the beam’s pulse width and bandwidth in the time and frequency domain. Previously, the beam had been analyzed using LabVIEW programs set up on Macintosh computers. The LabVIEW Visual Instrument Programs were connected directly to the instruments in order to analyze the laser beam signals and catalogue the information. As Fermilab no longer supported the Macintosh computers and switched its computer usage to PC’s these programs needed to be transferred to the new PC’s, upgraded, and a new one created to guarantee that the right kind of data was being obtained from the instruments. This paper explains how the laboratory continued its renovation phase by way of modifying, upgrading and creating new programs in order to acquire, store and analyze diagnostic data via remote control.
