The source of the poor vacuum in the backing line seems to be related to a dirty filter. We will try to find a replacement filter next week.
The problem seem to have started September 17th, when backing preassure CG1A went from 40 mTorr to 130 mTorr. CG1B remained around 30 mTorr. |

A Ta foil is placed in the target boat with separate slots for each endcap [same as elog 200]
The target boat is wrapped with 3-layers of Ta-heat shield. |

The endcaps are stacked together with a punched out disc of graphite foil placed in between each
endcap for separation so endcaps won't fuse together. |

Rick mentioned to me that the evaporator is ready for the next steps of the commissioning process.
In the chamber only the target leg heaters have current by-pass clamps on them.
The ionizer tube heaters do not have them because these lines do not have the same configuration as the others. The current by-pass clamps will
