Optimization of various procedures in terms of testing and manufacturing procedures of CERN’ homemade force transducer – the capacitive gauge

Abstract

This thesis has been written keeping in mind that it will serve two purposes. The first purpose is to present the steps that have been followed in order to further progress the overall optimization of a force transducer called the capacitive gauge. The second purpose is to guide all the people that will work on this topic in the future, to become familiar with this sensor and to adapt to some of the procedures this thesis includes. ln order to achieve these goals, this document has been divided into three chapters. The first chapter is aiming to introduce someone to the capacitive gauges. lt explains the working principals and describes the need for theirs production. The second chapter is aiming to present the steps that have been followed in order to improve the way they are being tested and calibrated and introduce the readers into newly adapted procedures to achieve these two. The third and final chapter is dedicated to the manufacturing procedure of the gauges. New ideas have been implemented and are presented in order to discover alternative ways to achieve better results, obtainable fasterand easier. Finally a sequence of the actions that have been followed to solve an existing problem with the manufacturing procedure of the capacitive gauges has been described, leading to some conclusion and suggestion paragraphs that should be followed, the problem will be resolved.
