A new generation SVSCf-plasma desorption time-of-flight mass spectrometer has been developed and placed into operation. The new features address particular requirements for high-mass studies but the overall design has been to markedly increase the flexibility for carrying out a variety of different kinds of experiments. The new features include a provision for controlling the SVSCf source-target and target-acceleration grid distance, an IR diode array for identification and precise positioning of targets, and different configurations of the field-free and ion detector region for post-acceleration, metastable ion analysis, and velocity focusing. Improvements have also been made in the data acquisition and analysis programs specifically for high-mass studies in order to obtain more accurate masses and a more complete picture of the complete ion distribution by generating digital difference mass spectra.
