Requirements
File:Requirements.pdf is the information given to external partners.
Information on materials
- AlMg3
- AlMg4.5
- See this link for [Wood's metal
Machining
- File:Mul Milling vs Turning.pdf is an old presentation by Frans Mul. The interesting conclusion is that 'turning' leads to a leaking foil, while 'milling' does not.
Vacuum measurements
- Dye penetrant inspection

* CERN can do this for the 1m long box
Activities
Starting October 2014 ...
- 2014/10/02: Machining of 5 drums ready (4 of 250 mu thickness, 1 of 150 mu thickness, all without leaks)
- 2014/10/20: Three drums with 0.1 micron holes sent to VDL (see ELOG)
- 2014/10/20: Received 1kg of Field's metal and 1kg of cerrolow 136 from Lowden Limited
Action items
- arrange a room for Willem (2014/09/18)
