Leak Detector
The Tate Lab has a counter-flow helium leak detector purchased from Varian in 1990 or so. It works well, but it is old and must be treated well. OSU MASC members may borrow it on request, but you must …
- know the principles of operation thoroughly.
- be able to draw, from memory, a schematic of the valve system to demonstrate your knowledge (there is a schematic on the LD to help you, but you should know how it.
- read the relevant portion of the LD manual.
- use a cart with AIR TIRES to transport the LD to buildings outside Weniger Hall. The MASC clean room has one - contact Chris Tasker or Rick Presley.
- have had instruction on the use of the LD by a member of the Tate group or an experienced user.
- sign out the LD on the page behind the door, and return the LD promptly.
Location & miscellaneous
Weniger 487. Various adaptors available (RETURN THEM!). There also is a sniffer probe that allows you to flood the DUT with He and detect from the outside. We have helium gas, but it's easier if you use your own.
Log (reverse chronological order)
- 10/8/13: Screws on filament casing loose from jolting. Chris Reidy took system apart, cleaned filaments, tightened bolts, recalibrated system. (This is NOT trivial - we don't want to do it again)
