PARA COMPROBAR LAS PREDICCIONES DEL MODELO ESTANDAR DE FISICA DE PARTICULAS, EL EXPERIMENTO ATLAS EN EL CERN NECESITA DETERMINAR EL ORIGEN, LAS TRAZAS Y LA ENERGIA DE LAS PARTICULAS QUE SE PRODUCEN EN LAS COLISIONES ENTRE PROTONES DEL LHC. LOS DETECTORES DE PIXELES DE SILICIO SON ESPECIALMENTE IMPORTANTES PARA LA DETERMINACION PRECISA DE TRAZAS Y VERTICES, LO QUE PERMITE LA SELECCION DE EVENTOS INTERESANTES A TRAVES DE LA IDENTIFICACION DE B-JET (B-TAGGING). LOS CALORIMETROS SON FUNDAMENTALES PARA MEDIR LA ENERGIA DE LAS PARTICULAS SALIENTES, Y NECESARIOS PARA INFERIR LAS PROPIEDADES DE LAS PARTICULAS QUE NO INTERACTUAN. PARA LA ACTUALIZACION DE LHC DE ALTA LUMINOSIDAD (HL-LHC), LOS SUB-DETECTORES DE ATLAS DEBEN MEJORARSE PARA MANTENER SU RENDIMIENTO. EL GRUPO IFAE ESTA DESEMPEÑANDO UN PAPEL PRINCIPAL EN LAS ACTIVIDADES DE ACTUALIZACION DE DOS LINEAS DE INSTRUMENTACION EN ATLAS: DETECTORES DE PIXELES Y MECANICA CALORIMETRICA._x000D_ _x000D_ IFAE YA HA HECHO CONTRIBUCIONES IMPORTANTES A LOS DETECTORES DE PIXELES DE ATLAS. LOS SENSORES 3D PRODUCIDOS EN IMB-CNM SON PARTE DE LA CAPA MAS INTERNA DE ATLAS, LA IBL. EL IFAE PARTICIPO EN LOS DIVERSOS ESFUERZOS QUE PERMITIERON LA INSTALACION DE IBL (EN 2014), DESDE LA CALIFICACION DE LOS SENSORES HASTA LA OPERACION EXITOSA EN ATLAS. DESPUES DEL IBL, IFAE CONSTRUYO POR COMPLETO E HIZO LA PUESTA A PUNTO EN EL CERN DEL DETECTOR DE TRAZAS ATLAS FORWARD PROTONS (AFP), TAMBIEN BASADO EN SENSORES 3D, QUE SE INSTALO EN 2016-2017._x000D_ _x000D_ PARA LOS DESAFIOS PRESENTADOS POR EL NUEVO DETECTOR DE TRAZAS DE ATLAS PARA EL HL-LHC (ITK), SE NECESITA UNA NUEVA GENERACION DE SENSORES DE PIXELES 3D. EL GRUPO YA DEMOSTRO QUE LOS SENSORES 3D, CON TAMAÑOS DE PIXELES MAS PEQUEÑOS Y SUSTRATOS MAS DELGADOS SON LOS QUE MEJOR CUMPLEN LOS REQUISITOS. ESTO LLEVO A SELECCIONAR LOS SENSORES 3D PARA LA CAPA MAS INTERNA DEL ITK._x000D_ _x000D_ SIN EMBARGO, INCLUSO CON LA EXCELENTE RESOLUCION DE POSICION QUE SE LOGRARA CON EL DETECTOR ITK, EL PILE-UP DEL HL-LHC DEGRADARA SIGNIFICATIVAMENTE EL RENDIMIENTO DEL DETECTOR. POR LO TANTO, SE HA PROPUESTO EL HGTD. LA TECNOLOGIA LGAD SE UTILIZARA EN HGTD, LA QUE FUE INICIALMENTE DESARROLLADA EN IMB-CNM. EN ESTE PROYECTO, SE LLEVARA A CABO LA PREPRODUCCION Y EL MONTAJE DE MODULOS LGAD PARA HGTD._x000D_ _x000D_ EL SISTEMA DE CALORIMETRO ATLAS TAMBIEN ES SENSIBLE AL AUMENTO DE LUMINOSIDAD QUE TRAERA EL HL-LHC. EN PARTICULAR, EL TILECAL DEBERA REEMPLAZAR SUS COMPONENTES ELECTRONICOS INTERNOS. LA ESTRUCTURA MECANICA QUE ALOJA ESTOS COMPONENTES ELECTRONICOS TAMBIEN DEBE SER REEMPLAZADA. IFAE PROPUSO UN DISEÑO MECANICO PARA LA ESTRUCTURA DE SOPORTE LLAMADOS MINI-DRAWERS Y PRODUJO PROTOTIPOS QUE FUERON PROBADOS Y ADOPTADOS POR ATLAS. COMO PARTE DE ESTE PROYECTO, IFAE COMENZARA LA PRODUCCION DE LOS MINI-DRAWERS PARA ATLAS._x000D_ _x000D_ EN RESUMEN, ESTE PROYECTO ES LA CONSOLIDACION DE PROGRAMAS ANTERIORES DE I+D. SE LLEVARAN A CABO PRODUCCIONES DE MODULOS DE SENSORES 3D PARA LA CAPA DE PIXELES MAS INTERNA DEL NUEVO DETECTOR DE TRAZAS DE ATLAS. EN PARALELO, PERO EN UN CRONOGRAMA DIFERIDO, LOS MODULOS DE LGAD SE FABRICARAN PARA LA ETAPA DE PREPRODUCCION DE HGTD. FINALMENTE, SE FABRICARA EL SOPORTE MECANICO PARA LA NUEVA ELECTRONICA TILECAL. ESTAS CONTRIBUCIONES CONSISTIRAN EN GRAN MEDIDA EN PRODUCTOS TOTALMENTE FABRICADOS EN ESPAÑA. (Spanish)

TO TEST THE PREDICTIONS OF THE STANDARD MODEL OF PARTICLE PHYSICS, THE ATLAS EXPERIMENT AT CERN NEEDS TO DETERMINE THE ORIGIN, PATH AND ENERGY OF THE PARTICLES THAT ARE PRODUCED IN THE LHC PROTON-PROTON COLLISIONS. SILICON PIXEL DETECTORS ARE ESPECIALLY IMPORTANT FOR THE PRECISE DETERMINATION OF TRACKS AND VERTICES, ENABLING THE SELECTION OF INTERESTING EVENTS THROUGH THE IDENTIFICATION OF B-JETS (B-TAGGING). CALORIMETER SYSTEMS ARE CRITICAL TO MEASURE THE ENERGY OF THE OUTGOING PARTICLES, AND NEEDED TO INFER THE PROPERTIES OF NON-INTERACTING PARTICLES. FOR THE HIGH-LUMINOSITY LHC UPGRADE (HL-LHC), THE ATLAS SUB-DETECTOR SYSTEMS HAVE TO BE IMPROVED TO MAINTAIN THEIR PERFORMANCE. THE IFAE GROUP IS PLAYING A LEADING ROLE IN THE UPGRADE ACTIVITIES OF TWO INSTRUMENTATION LINES IN ATLAS: PIXEL DETECTORS AND CALORIMETER MECHANICS. _x000D_ _x000D_ IFAE HAS ALREADY MADE KEY CONTRIBUTIONS TO THE ATLAS PIXEL DETECTORS. 3D SENSORS PRODUCED IN IMB-CNM ARE PART OF THE INNERMOST LAYER OF ATLAS, THE IBL. IFAE PARTICIPATED IN THE VARIOUS EFFORTS THAT LED TO THE IBL INSTALLATION (IN 2014), FROM SENSOR QUALIFICATION TO THE CURRENT SUCCESSFUL OPERATION IN ATLAS. FOLLOWING THIS SUCCESS, IFAE FULLY CONSTRUCTED IN-HOUSE AND COMMISSIONED AT CERN THE ATLAS FORWARD PROTONS (AFP) TRACKING SYSTEM, ALSO BASED ON 3D SENSORS, WHICH WAS INSTALLED IN 2016-2017._x000D_ _x000D_ FOR THE CHALLENGES PRESENTED BY THE NEW ATLAS TRACKER FOR THE HL-LHC (ITK), A NEW GENERATION OF 3D PIXEL SENSORS IS NEEDED. THE GROUP ALREADY DEMONSTRATED THAT 3D SENSORS, WITH SMALLER PIXEL SIZES AND THINNER SUBSTRATES, OUTPERFORM THE PLANAR SENSOR TECHNOLOGY IN TERMS OF RADIATION HARDNESS AND POWER DISSIPATION. THIS LED TO 3D SENSORS BEING SELECTED AS THE BASELINE FOR THE INNERMOST LAYER OF THE HL-LHC UPGRADE. IN THIS PROJECT, THE PRODUCTION AND ASSEMBLY OF 3D PIXEL MODULES FOR THE ITK WILL BE CARRIED OUT._x000D_ _x000D_ HOWEVER, EVEN WITH THE EXCELLENT POSITION RESOLUTION THAT WILL BE ACHIEVED WITH THE ITK DETECTOR, THE HIGH PILE-UP IN HL-LHC WILL SIGNIFICANTLY DEGRADE THE DETECTOR PERFORMANCE, SPECIALLY IN THE FORWARD REGION. THUS, A HIGH GRANULARITY TIMING DETECTOR (HGTD) THAT IS PLANNED TO MITIGATE THE EFFECT OF PILE-UP HAS BEEN PROPOSED. THE LOW GAIN AVALANCHE DETECTOR (LGAD) TECHNOLOGY WAS SUCCESSFULLY QUALIFIED THE FOR THE HGTD BY IFAE. IN THIS PROJECT, THE PRE-PRODUCTION AND ASSEMBLY OF LGAD MODULES FOR THE HGTD WILL BE CARRIED OUT._x000D_ _x000D_ THE ATLAS CALORIMETER SYSTEM IS ALSO SENSITIVE TO THE INCREASE IN LUMINOSITY THAT THE HL-LHC WILL BRING. IN PARTICULAR, THE TILE CALORIMETER WILL HAVE TO REPLACE ITS FRONT-END ELECTRONICS. THE MECHANICAL STRUCTURE THAT HOSTS THESE ELECTRONICS ALSO HAS TO BE REPLACED. IFAE PROPOSED A MECHANICAL DESIGN FOR THE SUPPORT STRUCTURE (CALLED MINI-DRAWERS, WITH EASIER MAINTENANCE AND INCREASED ACCESSIBILITY) AND PRODUCED PROTOTYPES THAT WERE TESTED AND ADOPTED BY ATLAS. AS PART OF THIS PROJECT, IFAE WILL START THE PRODUCTION OF THE TILECAL MINI-DRAWERS._x000D_ _x000D_ IN SUMMARY, THIS PROJECT IS THE CONSOLIDATION OF PREVIOUS R&D AND QUALIFICATION PROGRAMS. 3D SENSOR MODULES FOR HALF OF THE INNERMOST PIXEL LAYER OF THE ATLAS HL-LHC TRACKER WILL BE CARRIED OUT (ABOUT 0.5M2). IN PARALLEL, BUT ON A DELAYED SCHEDULE, LGAD MODULES WILL BE FABRICATED AND MOUNTED ON STAVES FOR THE HGTD PRE-PRODUCTION STAGE, TARGETING A 1M2 PRODUCTION. FINALLY, 40% OF THE MECHANICAL SUPPORT FOR THE NEW TILECAL ELECTRONICS WILL BE FABRICATED ALSO LOCALLY. THESE CONTRIBUTIONS WILL LARGELY CONSIST OF DELIVERABLES FABRICATED IN SPAIN. (English)
