Ease of maintenance really describes the new EB2 Source. You can
remove the top cover, crucible, and coil housing without removing
the source from the chamber! Think of it, you donít have to get the
magnet regaussed like other guns. Which will mean more up time for
you. (And more $$$$!) The magnet arms are not used for water
passages and there are no water lines to get bumped or cracked on
the coil housing brazement.
The EB2 comes in either a 4 pocket 7-40cc crucible or a 6 pocket
7-25cc crucible. A water-cooled cover plate and a hermetically
sealed coil assembly with a ceramic plug
with Kapton leads are standard. (No more shorted terminals from
plating.) We use a standard 270-degree emitter assembly.
