Most functions of the system are controlled by the central notebook computer by Windows™ - based
software functions. These include HV level settings, pulse height window, static acquisition of the images
and dynamic first-pass acquisition of images. Many variables are monitored from the same computer,
including detector pressure, detector temperature and detector HV+ and HV-.
