Wednesday, November 06, 2013, 17:36, John Wong, TaC, Target Boat #2, , In progress, Testing TaC matrix coating
|
The purpose of this experiment is to improve the TaC coating mixed with other metals as additives. The coating solution will be sprayed on Ta metal
(0.015" thick, same thickness as the target container).
The samples will be sintered at ~ 1800C. Once the process is completed, a graphite tube will be inserted into the tube, and then re-heated |

Friday, November 01, 2013, 17:20, Anders Mjos, , , , Problems, Backing pump needs new filter
|
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. |
