raith free until 23:30, chip left on holder

[krivoire at stanford.edu]

I took free time on raith this afternoon, so I am canceling my session  
from 20:30-21:30. The user with the session scheduled before me also  
seems to have canceled, as has the user with the session after me, so  
raith is now free until 23:30.

Also, I found a chip in the cross section mount on the sample holder.  
If it's yours, I left in next to the raith in a 1 inch round sample  
holder.
