    Notes: Abstract We describe a simple particle detector using the principle of the ion-electron converter. It detects ions and neutral particles, has low background noise (0.1 counts/s), and is bakeable at 280°C. The energy resolution of the electron detector is better than 2.0 keV, thus allowing the frequency distribution of the electron groups to be observed directly in the pulse height spectrum. The marked differences between the electron statistics for ions and for metastable neutrals are used in an application to mass-analysis. An improvement in signal to noise ratio by more than a factor of ten is achieved.

    Notes: Abstract Magnetic-structure analysis by means of spin-polarization analysis of the secondary electrons in a scanning electron microscope-type (SEM) experiment is demonstrated, using the LEED spin-polarization detector. The advantages in size, handling ability and efficiency, relevant for SEM operation, are pointed out. Limitations and future development are discussed.
