Actually we are in the process of putting a 1024X1024X24 bit camera
in our 200 KV hitachi.  You can do it two ways a camera with an
axis parallel to the beam looking down at the phosphor screen (but
there are problems with stray electrons, x-rays in the column) or,
as we are doing, using a ccd camera specifically made to fit in
the column and intersect the beam with the detector.  There is a
device of some type between the ccd and the beam, so you don't get
200 kv electrons zipping through the ccd - electrons go REAL far in
silicon and other semiconductors.  I believe we are getting the
camera from GATAN.

Hope this is of use.
