Problem innotec SNF 2005-03-31 00:04:25: Bell Jar hardly closes

[levi at snf.stanford.edu]

Hi all, 
Today it seems that you need to care fully lower the bell jar in order to close it properly. Please lower slowly and watch the bell jar to see if it closes. It seems that the bell jar is again rotating and has problems in closure. Also, on the crucible, to the left of target no. Three, there is a metal spot from evaporated residue that can not be easily cleaned.
