1. 3 Months Viva OUTLINE What is CLIC and PACMAN projects - Why PACMAN - what is the PACMAN challenge? What is project 3.1 of PACMAN PhD Thesis - Thesis subject - Hypothesis Resources for Thesis Timeline Cranfield 16/09/2014 by Iordan Doytchinov

2. CLIC and why PACMAN Project 2 5.56mm diameter 48.3km straight line assembly of 2 linac’s “particle guns” shooting at each other ~10nm diameter equivalent

3. What is the PACMAN challenge 3

4. PACMAN ESR 3.1 sub-project “If you grasp the principles – myths fall & Ideas take-off” David Lentink (TUDELFT) TED Conference Amsterdam (“ برج خليفة ‎, "Khalifa Tower“) – Dubai 2010 Babylon tower by Tobias Verhaecht (1561 – 1631) One off prototype example: Dominique Loiseau - the Rose de Temps clock Extremely costly on time & money High number production (thousands): ‘Swatch’ mass production of Swiss made high quality wrist watches

5. 5000 of them! How is this can be done at industrial not prototype scale? shape accuracy of +/-10 microns meters for critical surfaces for up to 2 meters length Shape Assembly accuracy of +/- 20,microns for up to 2 meters 2000km +/-1 cm Comparison to earth size topology of form specification Iordan D. at PACMAN: PhD Thesis subject

6. Before, Now 6  Current practical work assembly with jig tooling (fit key concept):  Use of kinematic tool to set location/align components (horizontal VS vertical assembly – investigating effect of gravity) --> Geometric CMM + Magnetic measurement + GD&T analysis (KOTEM software) to be performed Is tooling giving better results than kinematic assembly alone? What about tooling + kinematic assembly?  Done (best so far) kinematic assembly using central pin: approx. ±150 μm obtained  Selected a better assembly method (quadrants positioned by axial pins): approx. ±10 μm

7. Hypothesis: 7 “Developing a Tool and Technique/methodology for the optimal uncertainties minimisation to increase accuracy and precision/repeatability for precise electro- mechanical assemblies in economically viable environment” How can unperfected components to be put together to produce a high precision assembly with relevant electromagnetic quality? With relative industrial ease? Manufac turing Design Hard/expensive to optimise Measurement + evaluation  Methodology + Jig + Software Assembly stage + jig/tooling Magnetic measurement

8. Resources required 8  Knowledge: -System Integration, conceptual design. ‘make it good first time’ -Precision systems design -Materials selection for precision and manufacturability -In-built uncertainties due to manufacturability methods processes -Uncertainty bill due to metrology measurement -Assembly methods induced uncertainties -Final function verification induced uncertainties  Software Tools: -CATIA -ANSYS -MATLAB -KOTEM, Sigmetrix  Hardware and facilities: -Quadrupoles existing prototypes + future one to be manufactured -Final PACMAN test bench -CERN and DMP metrology and manufacturing departments -Final PACMAN test bench  Technical support: -Cranfield (Supervisors) -CERN specialists (M.Modena, Stefano Sgobba, Bertrand Niqueverst and other) -External Specialist (L.Charvier (now at Piaget watches) K. Doytchinov (KOTEM) and others

9. Time plan (see Gantt Chart) 9  Before 9 month VIVA:  After 9 month VIVA:  Thesis finalisation:
