I was trying to make a joke about it, since Lachlan seemed to be 
drawing a lot of fire when he is really a very helpful person.

I agree "en principe" that Q-plots are a good idea, or better yet 
1/d*d plots which have a more uniform density of peaks.  But 
I believe we neutron people should conform as far as possible to 
the X-ray world if we don't want to make neutrons look even 
more 'exotic'.

Hans himself is planning a convential D2B-like machine (he said so
at the meeting).  There is already a TOF machine on the old Munich
reactor - it was the inspiration for the first ISIS machine, which
is of course a 'good thing', but on a reactor it requires huge samples.

You can of course build a high intensity reverse Fourier chopper 
powder machine on a reactor, as pioneered by the Finnish-Russian 
group, but then the background is very high.  Perhaps we should
have an opinion from some-one who has actually tried it :-)

But then Paolo might like to follow the Swiss example - convert
ISIS to a steady state source and build a D20-like conventional 
machine - which I am willing to bet will be very successful knowing
the Swiss. (Hey, don't take this suggestion too seriously guys :-)
