Typical deflection coils have a serious problem with fast vector

N.J.) explicitly for such purposes, with rather elaborate mounting for
special CRTs, giving very fine adjustment capability for all elements of
yoke position.

Boy does that bring back memories. I used Celco yokes on many a job
in a previous "incarnation" :-) at a R&D place in PA. I did a lot
of CRT circuit design for various IR systems. Even made a trip to
Celco to coordinate a special design once. Great people to work
with, at least back in dim dark ages of 1960s.


Hmm ... IR systems. Did you ever wind up dealing with the U.S.
Army Night Vision Labs? That is where I first encountered IR systems,
with the first being a scanned single sensor printing onto 4x5 Polaroid
film -- made by Barnes, IIRC.

Enjoy,
DoN.
