Magnetic and Mechanical Design for a 16 T Common Coil Dipole for FCC

EuroCirCol es un estudio conceptual de la infraestructura post-LHC basada en un colisionador de hadrones con energía de hasta 100 TeV. En el paquete de trabajo de diseño de los imanes para el acelerador, se analiza la viabilidad de dipolos de 16 T. Este artículo muestra el diseño electromagnético y estructural de un imán de tipo CommonCoil para alcanzar la calidad de campo requerida teniendo en cuenta los parámetros y condiciones aplicables a EuroCirCol. Se han utilizado métodos de elementos finitos para analizar las tensiones y fuerzas así como los campos magnéticos, requiriendo numerosas iteraciones para alcanzar un diseño posible

A EuroCirCol is a conceptual design study for a post-LHC research infrastructure based on an energy-frontier 100 TeV circular hadron collider. In the frame of the high-field accelerator magnet design work package of this study, the feasibility of a 16 T dipole in a common coil configuration is being studied. This paper shows the electromagnetic design optimization performed to achieve the required field quality while minimizing the superconductor volume and taking into account the input parameters and assumptions of the EuroCirCol study. The finite element models have been used to analyze the stress distribution and deformations under the large Lorentz forces due to the very high magnetic field. Several iterations have been necessary to obtain a feasible magnet design. The 3-D electromagnetic calculations are also included in this paper.
