Abstract :
A tracking device based on the GEM (gas electron multiplier) scintillation using a high-resolution cooled CCD camera was developed. The CCD is sensitive to the 400-1000 nm band and standard glass photographic lenses are used. The active gas is an Ar-CF4 mixture. The prototype detector is described and images of single alpha tracks are presented. The light yield and detector performance for several other gaseous mixtures, such as 4He-CF4, have also been investigated
