Yes I do mean automated stepping; I didn’t realize there were so many sub-developments: A goniometer driven by a stepper motor with a counter/timer monitoring the output from the detector.
Younger than you thought?!? This is a first! Jim James P.

If you mean just digital data, then its Shull and Wollan in the late 1940's. Neutrons were always digital of course; we had film and cameras much later than for x-rays. You must be younger than I thought Jim, with your 1980 memories, or else I am older than I think :-) Alan. -- ______________________________________________ Dr Alan Hewat, NeutronOptics, Grenoble, FRANCE <alan.he...@neutronoptics.com<mailto:alan.he...@neutronoptics.com>> +33.476.98.41.68 http://www.NeutronOptics.com/hewat ______________________________________________
