Entry number 316549

This entry is a followup to: 316548

We've noticed the rates are not very reproducible on BeO
and the last time needed a lower attenuator and narrower slit.
I guess I should explain this in the instructions.  Main thing
is you don't want to be overwhelmed with rate when you put
in Pb/diamond; that's why you do BeO first.  I guess even 20 kHz
would be ok but 200 kHz sounds high.
