3D model, drawings
The CATIA model and stp files for the RF box can be found on Martin's webpage:

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: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

Torlon coating
- Sub-project plan (june 2016): http://www.nikhef.nl/~wouterh/share/ProjectPlan_Torlon.pdf

NEG coating
- File:Mul NEGcoating2005.pdf Presentation by Frans Mul on application of NEG coating at CERN
Vacuum measurements
- integral tests at nikhef:
- Dye penetrant inspection
- Information provided by Gonzalo ARNAU IZQUIERDO (materials engineer at EN/MME,CERN)
- Measurements were done by EN-MME Alexandre Gerardin:
