- ELOG: https://webapps.nikhef.nl/elog/VELO_Upgrade_RFBox/
- Massi's twiki on foil thinning: https://lbtwiki.cern.ch/bin/view/VELO/FoilThinning
Planning
Link to project plan: [project plan]
Rough timeline:
- R&D/prototyping 2014-2015
- Production 2016-2017
- Installation 2018
People
- Willem Kuilman
- Berend Munneke
- Johan Kos
- Martin Doets
- Rob Walet
- Tjeerd Ketel
- Wouter Hulsbergen
Drawings
The CATIA model and stp files for the RF box can be found on Martin's webpage:
http://www.nikhef.nl/~martind/Velo%20boxes/
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.
NEG coating
- File:Mul NEGcoating2005.pdf Presentation by Frans Mul on application of NEG coating at CERN
Vacuum measurements
- Dye penetrant inspection
* Information provided by Gonzalo ARNAU IZQUIERDO (materials engineer at EN/MME,CERN)
* https://www.nde-ed.org/EducationResources/CommunityCollege/PenetrantTest/PTMaterials/ptmaterials.htm
* http://en.wikipedia.org/wiki/Fluorescent_penetrant_inspection
* Measurements were done by EN-MME Alexandre Gerardin:

* https://lbtwiki.cern.ch/pub/VELO/FoilThinning/Metallurgy_report_1409244.pdf
* 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)
