Complete data acquisition and analysis system for low-energy electron–molecule collision studies

A complete data acquisition system has been developed that can work with any personal computer irrespective of the operating system installed on it. The software can be used in low and intermediate electron-energy collision studies with ground-state molecules in gas phase using a combination of RS-232, GPIB, and USB-interfaced devices. Various tabletop instruments and nuclear instrumentation module (NIM) -based electronics have been interfaced and have communicated with the software, which is based on LabVIEW. This is tested with dissociative electron attachment (DEA) and polar dissociation studies to oxygen molecule and successfully used in a DEA study of carbon monoxide and carbon dioxide. (paper)
