maximum emission of 370nm; and a decay constant of 25 ns. It has been cho-
sen for its optical as well as mechanical and thermal characteristics that make
this material particularly suited for applications in a harsh environment such
as inside a small sealed accelerator, especially its resistance to heating during
the tube manufacturing.
