Dear Harry,
Your last sentence below made me think that you might well be
interested in this detector, the Mark II multiwire chamber that was
built by Georges Charpak at CERN for Roger Fourme and Richard Kahn at
LURE. It was this detector that enticed me to go and work at LURE, and
it was in order to create appropriate software for it that I organised
and ran the EEC Area Detector Software Workshop (1986-1989) that is
still quoted nowadays as the inspiration for the DIALS project.
It was on this detector that Wayne Hendrickson came to collect a
MAD dataset on a Holmium derivative (I think) of Bill Weiss's mannose
binding protein, using the re-engineered MADNESS software written
during the Workshop (it was fashionable for everything to be called
MAD in those days ...) . The monochromator was not very well behaved
and produced a continuous drift in wavelength that had to be tracked
as part of the subsequent phase calculations, but the detector itself
performed superbly. Unfortunately it was limited by its technology to
an overall counting rate of about 500k counts/second.
I hope this will enhance your collection of obsolete detectors.
This one was a unique copy. I want to thank Thierry Prangé for sending
me this picture during the summer.
With best wishes,
Gerard.
