1. Running and Future Projects at Helsinki University M. Aicheler 31.01.2013

2. CLIC RF structure R&D • high-precision assembly & machining R&D for CLIC RF structures (in collaboration with VTT & Finnish companies…) • model thermo-mechanical behaviour of CLIC module during operation • industrialisation & cost study for CLIC RF structures • development of technique for dynamic vacuum measurement (DVM) & for internal geometry measurement for CLIC accelerating structure (in collaboration with prof. E. Haeggström, University of Helsinki) RF structure prototype disk manufactured in Joensuu @ North Karelia University of Applied Sciences. Test setup for DVM development in Helsinki

3. MeChanICs • FP7/People/IAPP (Industry-AcademiaPartnerships and Pathways) projectMeChanICs, “Marie Curie linking Industry to CERN” • start September 1st 2010, end 30th of August 2014 • budget: ~ 1 M€ • to enhance knowledge exchange between Partners in high precision manufacturing by two-way intersectoralsecondments and dissemination workshops

4. MeChanICs • Objective: enable & enhance long term industry participation in CLIC, Compact LInear Collider, RF structure R&D • Participation in each step of RF structure manufacturing • - 5 Work Packages

6. ‘TAVAKS’ (~”To Habit”) Customer oriented development of ultrahigh precision manufacturing in Finnish industryTArkuuusValmistuksen Asiakaslähtöinen valmiuksien Kehittäminen Suomalaisessa teollisuudessa Project introduction 27.9.2012 University of Helsinki, Helsinki Istitute of Physics, HIP Technical Research Centre of Finland VTT North Carelia University of Applied Science, NKUAS

7. TAVAKS Objectives The aim of the project is to increase the knowhow and capability of manufacturing ultra-high precision components and assemblies in Finnish industry. Productions steps from raw material to finalized components and assemblies are considered as well as the requirements and interaction between different steps in the production chain. 6 work packages: WP 1 Material research WP 2 Ultra-high precision machining&Pre-machining WP 3 Diffusion bonding and laser welding WP 4 State of the Art and Market analysis WP 5 International cooperation WP 6 Coordination Development work is based on CLIC components and assemblies. One goal is to establish capability to produce CLIC disks and test components and support CLIC development work.
