Mikail Acar
Control system engineer, CERN (Genève)
Actuellement en poste en tant que Responsable du pilotage des quadrupole low beta du LHC (large Hadron Collider), ma mission s’articule autour de trois axes principaux : l'installation de moteur pas à pas, le repositionnement à distance de ces derniers au micron puis la supervision. Ce poste que j’occupe depuis environ 5 ans m’a permis de découvrir la dimension managériale et technique d’un poste d’encadrement dans le plus grand centre de recherche au monde: le CERN.
Je souhaite aujourd’hui continuer dans le même secteur d’activité mais élargir mes connaissances techniques. Mon parcours universitaire me permet de m'orienter en électronique, informatique (industriel) ou électrotechnique.
Curieux, dynamique, ayant le sens de l’écoute et du travail en équipe, je reste ouvert à toute opportunité d'offre d'emploi.

18 contacts2006 - 2009The superconducting low-beta quadrupoles of the Large Hadron Collider (LHC) located at either side of each experiment are used to focus the beam. The aim of my job was to position remotely these heavy magnets with a micrometric resolution following 5 degrees of freedom. (1) Stepper motors have been used to motorize the system. Assembler program has been used in order to control/command the motors (microprocessor C8051F02). The technical specification for motor, resolver, gearbox, the control (converter), the tests, the EMI, the validation and finally the installation in the LHC of the motors have been done successfully.
(2) Capacitive sensors have been chosen to monitor the magnets. Consequently, an acquisition system for theses sensors has also been developed. Their role was to collect the data and act to some parameters (cut of power supply, reset the voltage reference). To fulfill all the requirements, microcontroller ADUC834 have been used and programmed in C language. Analog (sensors input), digital (ADC) aspects have been controlled and validated.
(3) PVSS has been chosen to monitor this entire complex. The goal here was to develop panels and imagine the supervision for all these devices. PVSS script language (similar C language) has been used to achieve this point.
(4) All these raw data have been transferred to an oracle database for long term storage (SQL).
(5) Study and simulation with flux 2D of the hybrid stepper motor.
(6) Additional and personal work: study of the magnets in closed loop system. Matlab has been chosen to see the behavior of the magnet in a closed loop system. Both mean least square as well as transfer function have been studied for this point.
Programming a tridimensional graphic under Linux. The aim was to develop software for biologist which was able to display any matrices on 3D graphics. The user was able to move and turn the graph with mouse in order to see all point plotted.
