Development of an automated scanning monochromator for sensitivity calibration of the MUSTANG instrument.

Abstract

An Automated Scanning Monochromator was developed using an Acton Research Corporation (ARC) monochromator, Ealing photomultiplier tube and a Macintosh PC, in conjunction with LabVIEW software. The LabVIEW Virtual Instrument written to operate the ARC monochromater is a mouse-driven user-friendly program developed specifically for automated spectral data measurements. Resolution and sensitivity of the Automated Scanning Monochromator system have been determined experimentally. The Automated Monochromator was then used for spectral measurements of a platinum lamp. Additionally, the reflectivity curve for a BaS04 coated screen has been measured. Reflectivity measurements indicate a large discrepancy with expected results. Further analysis of the reflectivity experiment is required for conclusive results.
