Requirements
File:Requirements.pdf is the information given to external partners.
Information on materials
- AlMg3
- AlMg4.5

Machining
- File:AfnameRapport DMF260-11.pdf Specification of Nikhef's DMF260-11 by the manufacturer
- 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.
Fixing leaks
