We have contaminated two Ti sources this week after using the Au with
the Tungsten liner.
Not sure at this time why the Au was spraying lateral under the hearth
and contaminating sources in the right and left pockets. Power should
be at 9% to 13% range using the old source without a liner.
1) Power may have been too high (7%) would like to keep it below 5%
2) The level of Au may play a factor in this. (too low)
Any information that you may have would be greatly appreciated.
