[G12] new secondary beam observation

[John Price]

Hi Moskov:

This plot (the one I sent out just now) has completely revamped my
research program here.  I'm now interested in looking into basically
anything I can do with a beam *other* than a photon or an electron.  

So, yeah.  It's on the list.  A K_s will travel something like 2-3 cm
before decaying (c-tau=2.7cm), which is comparable to the mean path it
will have through the target before leaving out of the cylindrical wall.
This gives us a reasonable chance of seeing it do something interesting
other than decay.

Now I just need to find 6-7 more students...  :)
