Refcav heat shield tubes removed from vacuum can. End caps were placed into baking rig, heat was turned on after pumpdown at Sat Sep 30 16:25 2017.
For reference variostat was set to 40% of 110V, which seemed to be about right for 100 C yesterday.
Parts are now cleaned and ready to bake. I've put them in a UHV foil lined box with a TX1010 wipe in the bottom to stop scratching. Its a very small vacuum can so I'm baking the two tubes first and will do the end caps and misc parts in the next cycle. I started a bake cycle at 7:45 pm for just the shields and will let it go for a few hours at 100 C.
This time I wrapped the vacuum can initially in copper foil, then the heater strap followed by a generous amount of food grade aluminum foil. Its heating up much faster in this configuration. I wasn't sure how the cloth wipes would fair under baking so the shields were very gently placed directly on an aluminum lining inside the can.
