Triple-axis spectrometers worldwide.

Dear colleague

I am attempting to determine the number of triple-axis spectrometers (TAS)
in the world.  To this end I have tried to contact appropriate people at
all research reactor facilities that might reasonably have one or more
such instruments.  Below is a summary of the information I have so far
managed to collect.  I would appreciate your comments, such as new, corrected,
or improved information for a reactor site, sites omitted from my list, 
suggestions of people to contact at sites for which I have no information, etc.
Thanks in advance for any help you can give me.

In this survey I have assumed (I think reasonably) that there are no 
triple-axis instruments at pulsed neutron sources. 

I take this opportunity to thank the many collegues who have responded to my
enquiries up to now about triple-axis spectrometers.  I apologize that I 
have not thanked them individually.
