Scientific project
Starting point = challenge concerning the pre-alignment of the CLIC components.
Requirements:
Current strategy
Series of steps: fiducialisation of the components and their support, alignment on a common support, alignment in the tunnel using sensors fiducials.
but time and precision consuming
considering the number of components to be aligned…
The zero of each component will be included in a cylinder with a radius of a few microns:
14 µm (RF structures & MB quad BPM) 17 µm (MB quad)
3
Fiducialisation of components
Fiducialisation of their common support
Alignment on a common support
Scientific project
PACMAN project:Propose and develop an alternative solution integrating all the alignment steps and technologies at the same time and location (CMM machine)
Technologies concerned:
Beam
Instrumentation Metrology Micrometric alignment positioning Nano
Magnetic measurements
Ultra high precision engineering
Scientific project
Long term
• Automation of the process
• Simplification (method, duration, components)
• Extrapolation to other components
• Optimization of performances and precision in all domains
• Preparation of industrialization Short term: some key issues
• Integration, ultra-high precision engineering and manufacturing
• Magnetic measurements with a vibrating stretched wire (and alternative based on printed circuit boards rotating search coils)
• Determination of the electromagnetic centre of BPM and RF structure using a stretched wire
• Absolute methods of measurements: new measuring head for CMM, combination of FSI and micro-triangulation measurements as an alternative
• Improve seismic sensors and study ground motion
• Nano-positioning system to position the quadrupole and BPM Build a prototype alignment bench
Marie Curie action
A Marie Curie action provides EC funding for post-grads to participate in CERN projects
PACMAN project belongs to an ITN = Initial Training Network
o Purpose:
o Improve career perspectives of Early Stage Researchers (ESR) in
both public and private sectors
o Make research careers more attractive o Objectives:
o Respond to well-identified needs in defined scientific or
technological areas
o Expose the researcher to other sectors
o Offer a comprehensive set of transferable skills
There are 3 different ITN programs: multi-ITN, IDP and EID. PACMAN is an
Innovative Doctoral Program
o Management at CERN o 10 ESR
o ESRs must be working towards a PhD universities must supervise the PhD student
o Associated Partners from universities and industry

PACMAN
High quality of the training program:
o Training through research at CERN and at universities
o Exchange of knowledge through secondments in the industrial partners
o Scientific, academic and technological training courses including trainings
organized by PACMAN
o Transferable skills training courses
3 PACMAN workshops, with training and dissemination purposes:
o First workshop: setup the scenario: presentation of the state of the art by
industrial partners, presentation of the PhD subjects by ESR
o Second workshop: present the first results and conclusion concerning each
subject
o Third workshop: conclusion of the project in front of invited experts
A workshop on Intellectual Property and technology transfer, organized with the KT group at CERN, including a training session prepared by the WIPO (World International Property Organization), with other participants as Hexagon, TNO and NI, with practical cases prepared by their IP department.
Participation in external conferences and workshops : LCWS, IBIC, IWAA, MT, IMMW, IPAC, etc.
Special emphasis put on women scientists Dedicated outreach activities
