PACMAN Kick-off meeting




Scientific project

Study for an e- e+ collider with a centre of mass energy of 3 TeV

  • Introduction to the CLIC project
  • Sub-µm beam size, down to a few nm at the IP
  • A number of challenges to be mastered, among which:
    • Very tight tolerances of alignment of components, to about 10 µm over a distance of 200m
    • Active stabilization of the quadrupoles in the nanometre range required

Scientific project

  • Introduction to the CLIC project
  • Based on a two beam acceleration concept
  • Each linac consists of more than 10 000 modules (with a 2m length)

Scientific project

  • Introduction to the CLIC project
  • Different types of components:
    • Quadrupoles :
      • MB quadrupoles: ~ 4000
      • DB quadrupoles: ~ 42 000
    • BPM: one per each quadrupole
    • Accelerating structures: ~ 142 800
    • PETS components: ~ 71 000

Scientific project

  • Starting point = challenge concerning the pre-alignment of the CLIC components.
    • Requirements:
  • 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)
    • 20 µm (DB quad)
  • Active alignment consists of two steps:
    • Determination of the position by alignment sensors
    • Re-ajustment by actuators
  • 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…

Fiducialisation of components

Fiducialisation of their common support

Alignment on a common support

Whole assembly ready to be aligned


Special case of MB quadrupole

    • One additional step: the stabilization / nano-positioning system

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:

Ultra high precision engineering

Micrometric alignment

Magnetic measurements

Beam Instrumentation

Nano positioning




Scientific project

  • 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
  • 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

Outcome = 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
      • Purpose:
        • Improve career perspectives of Early Stage Researchers (ESR) in both public and private sectors
        • Make research careers more attractive
      • Objectives:
        • Respond to well-identified needs in defined scientific or technological areas
        • Expose the researcher to other sectors
        • Offer a comprehensive set of transferable skills
  • There are 3 different ITN programs: multi-ITN, IDP and EID. PACMAN is an Innovative Doctoral Program
    • Management at CERN
    • 10 ESR
    • ESRs must be working towards a PhD  universities must supervise the PhD student
    • Associated Partners from universities and industry
    • Secondment of at least 3 months in industry for each ESR.

Marie Curie action  PACMAN

  • High quality of the training program:
    • Training through research at CERN and at universities
    • Exchange of knowledge through secondments in the industrial partners
    • Scientific, academic and technological training courses including trainings organized by PACMAN
    • Transferable skills training courses
  • 3 PACMAN workshops, with training and dissemination purposes:
    • First workshop: setup the scenario: presentation of the state of the art by industrial partners, presentation of the PhD subjects by ESR
    • Second workshop: present the first results and conclusion concerning each subject
    • Third workshop: conclusion of the project in front of invited experts
