This container is prepared for a backup UCx target (otherwise it will be used for development purposes).
The container is coated with TaC; one layer of Ta-heat shield is used. |

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. |

5 samples were prepared at UBC MTRL using Sol-gel tetraethyl orthosilicate (TEOS) coated on electrospun polyacrylonitrate (PAN).
Each sample is sandwiched in between graphite foils. |

SiC powder (<1um) [10%] was mixed with PAN solution [10%]. Solution was sonicated before e-spinning.
Fiber mat was binded to graphite foil and heat treated to 250C in air for 1 hour. |

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. |
