|
Friday, July 31, 2015, 15:39
A Ta tube was coated with TaC. The inner of the tube was filled with TaC solution and the excess was drained out to give a homogenous coating.
The outer layer of the tube was brushed with TaC. |

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.
The end caps are further wrapped in a larger piece of graphite foil to hold together as a tube [same method used in elogID # 158] |

The turbo pump was found to be faulty. The pump couldn't get on full speed and eventually timed out. Vacuum group inspected the pump
and it is time for a service. |

Heat treatment of 2 bullet-shaped Nb samples in a LP-SIS container; it is just that we don't have a target boat.
Container is wrapped with 12" in total length. A strip of Nb foil is used as an underlayer for the samples to sit on top. |

The purpose of this experiment is to determined the limiting operating temperature for Beta-SiC. To do so, samples will be heated in sequence
to observe any volatile Si coated on the window. The coating is observed above 1400C for the conventional SiC (mixuture of alpha and beta) and this
coating leads to HV shorting problem. |
