Abstract
Two novel designs have been generated for permanent magnet based quadrupoles for the Compact Linear Collider (CLIC). A first high strength permanent magnet quadrupole has been successfully assembled and testeda. The four yokes had been manufactured to close tolerance and in a controlled environment to meet the magnetic characteristic specification. For industrialization purposes a lower standard was chosen to simulate and gather experience for large production planning and assembly. Magnetic modeling indicates that the yoke nose pole shape and inscribed radius need to be tightly controlled in order to meet the stringent specification for magnetic field quality set down by CERN. A nominal figure of 10 micrometre as tolerance range will guarantee this. The process to convert Coordinate Measurement Machine data of high accuracy components into meaningful assembly dimensions is a complex and high manual input undertaking. A number of processes are required to use the data obtained, translate it between various formats and manipulate it in a number of different software to suit the goal of obtaining a physical assembly as close as possible to the nominal ideal model. Traditional CMM methods differ from this approach in terms of accuracy and do not utilize data beyond the comparison between manufactured and nominal component dimensions. The process of how to arrange the manufactured yokes to remain within this tolerance is described in this document.
