New 600 keV electron accelerator for high-speed phenomena FEBETRON 7 0 6 T h e o s c i l l o g r a p h above shows the transmitted current in the external electron beam of a Febetron 706 accelerator. The amplitude is 7000 amperes, the pulse length is 3 nanoseconds at the half current points. The peak beam power is more than 3000 m e g a w a t t s — e n o u g h to activate a lot of mechanisms in a hurry! What can it be used for? For one thing, the study of fast decay processes—shortlived chemical radicals, electron induced fluorescence, electronic radiation effects, etc. And the electron range is ideal for both gas radiolysis and for cellular biological specimens where dose rate effects may be studied. As a diagnostic tool it can take highs p e e d p h o t o g r a p h s — b o t h X-ray and electron beam s h a d o w g r a p h s with " s t o p m o t i o n " clarity for a wide range of object thicknesses and densities. And it may be useful as a dynamic electron beam probe for gas densities in shock waves. Design is similar to that of other Fexitron and Febetron instruments w h i c h are available in a complete line of time-tested equipment ranging from 50 kV to 2 million volt systems. Fexitron field emission X-ray devices have enjoyed widespread customer acceptance for more than eight years—the Febetron field emission beta ray devices for more than three years. At $14,970 the Febetron 706 provides a precision instrument for quantitative research at relatively low cost. Energy is r e p r o d u c i b l e to -*; 5 % rms. Time of fire is c o n t r o l l e d to ±- 50 ns (standard) or ± 7 ns (special). Several beam parameters are adjustable. A high signal-tonoise ratio is provided by coaxial con-

struction and metal enclosure. It is economical to install (power required is only 110 v, 20 amps), simple to operate, requires little m a i n t e n a n c e , has long life.
