NEXT (NEUTRINO EXPERIMENT WITH A XENON TPC) ES UN EXPERIMENTO PARA BUSCAR DESINTEGRACIONES DOBLE BETA SIN NEUTRINOS (BBONU) CUYA DETECCION DEMOSTRARIA UNIVOCAMENTE QUE EL NEUTRINO ES UNA PARTICULA DE MAJORANA (ES DECIR SU PROPIA ANTIPARTICULA) Y SUPONDRIA UN DESCUBRIMIENTO CON PROFUNDAS CONSECUENCIAS EN FISICA DE PARTICULAS Y COSMOLOGIA. _x000D_ _x000D_ EL ISOTOPO ESCOGIDO POR NEXT ES EL XE-136. EL EXPERIMENTO DISPONE DE CIEN KILOS DE GAS XENON ENRIQUECIDO AL 90% EN XE-136. LA TECNOLOGIA SE BASA EN EL USO DE CAMARAS DE PROYECCION TEMPORAL OPERANDO A UNA PRESION TIPICA DE 15 ATMOSFERAS (HPXE). LAS CARACTERISTICAS PRINCIPALES DE ESTA TECNICA EXPERIMENTAL SON: A) EXCELENTE RESOLUCION EN LA MEDIDA DE LA ENERGIA; B) CAPACIDAD DE RECONSTRUIR LA TRAYECTORIA DE LOS ELECTRONES EMITIDOS EN LA DESINTEGRACION, LO QUE REFUERZA LA CAPACIDAD DEL EXPERIMENTO PARA REDUCIR EL RUIDO DE FONDO; C) ESCALABILIDAD A GRANDES MASA Y D) LA POSIBILIDAD DE REDUCIR EL RUIDO DE FONDO HASTA NIVELES DESPRECIABLES MEDIANTE LA TECNICA CONOCIDA COMO BATA (DE LAS SIGLAS EN INGLES, BARIUM TAGGING)._x000D_ _x000D_ EL EXPERIMENTO NEXT CONTEMPLA CUATRO FASES: I) DEMOSTRACION DE LA TECNOLOGIA HPXE CON PROTOTIPOS QUE USAN 1 KG DE XENON NATURAL; II) MEDIDA DE LOS RUIDOS DE FONDO Y DE LA SEÑAL DEL PROCESO PERMITIDO (BB2NU) CON UN DETECTOR (NEW) BASADO EN 12 KILOS DE XENON ENRIQUECIDO Y OPERANDO EN EL LABORATORIO SUBTERRANEO DE CANFRANC (LSC); III) BUSQUEDA DE DESINTEGRACIONES BB0NU CON EL DETECTOR NEXT-100, UNA REPLICA A ESCALA 2:1 (EN TAMAÑO) Y 8:1 (EN MASA) DE NEW, QUE USARA POR TANTO 100 KILOS DE GAS ENRIQUECIDO; IV) BUSQUEDA DE DESINTEGRACIONES BBONU CON EL DETECTOR BEXT (BARIUM-TAGGING EXPERIMENT WITH A XENON TPC), CON UNA MASA DE ALREDEDOR DE UNA TONELADA DE XE-136, QUE INTRODUCIRA LA TECNICA DE BATA PARA REDUCIR EL RUIDO DE FONDO HASTA NIVELES DESPRECIABLES. _x000D_ _x000D_ LA PRIMERA FASE DE NEXT HA SIDO COMPLETADA CON EXITO DURANTE EL PERIODO 2009-2013. DURANTE ESTA ETAPA SE HAN CONSTRUIDO LOS PROTOTIPOS NEXT-DEMO (IFIC) Y NEXT-DBDM (BERKELEY) QUE HAN DEMOSTRADO LAS CARACTERISTICAS PRINCIPALES DE LA TECNOLOGIA. EL EXPERIMENTO SE ENCUENTRA EN ESTOS MOMENTOS EN SU SEGUNDA FASE. EL DETECTOR NEW ESTA SIENDO CONSTRUIDO POR LA COLABORACION Y OPERARA EN EL LSC DURANTE EL AÑO 2015. LA FINANCIACION DEL DETECTOR NEW PROVIENE DE UN ADVANCED GRANT (ADG/ERC) CONCEDIDO EN 2013 AL IP DE ESTE PROYECTO (OPERATIVO DESDE FEBRERO DE 2014 A FEBRERO DE 2018). EL DETECTOR NEXT-100 SUPONE LA TERCERA FASE DEL PROYECTO. SE CONSTRUIRA Y PONDRA A PUNTO DURANTE 2016 Y 2017 E INICIARA SU TOMA DE DATOS EN 2018. LA CUARTA FASE DEPENDE DE LOS RESULTADOS DE LA FASE TRES, EN LA QUE SE PODRIA REALIZAR YA UN DESCUBRIMIENTO. PREVISIBLEMENTE, BEXT PODRIA FUNCIONAR EN EL LSC A PARTIR DEL 2020. _x000D_ _x000D_ NEXT ES UNA COLABORACION INTERNACIONAL, LIDERADA POR GRUPOS ESPAÑOLES Y CON UNA FUERTE CONTRIBUCION DE GRUPOS NORTEAMERICANOS. EL DESARROLLO DE LA TECNOLOGIA LASER NECESARIA PARA EL BATA SE REALIZA EN COLABORACION CON EL CENTRO DE LASERES PULSADOS DE SALAMANCA (CLPU). _x000D_ _x000D_ ESTE PROYECTO DE INVESTIGACION REQUIERE COFINANCIACION PARA DESARROLLAR LA FASE TRES DEL EXPERIMENTO. CONCRETAMENTE, SE REQUIERE: A) FONDOS PARA ADQUIRIR UNA PARTE DE LOS EQUIPOS Y MATERIAL FUNGIBLE NECESARIOS PARA LA CONSTRUCCION DEL DETECTOR NEXT-100 (COFINANCIADO POR EL ADG Y LOS FONDOS PROVENIENTES DE LA COLABORACION); B) FONDOS PARA UNA PARTE DEL PERSONAL CIENTIFICO Y TECNICO; Y C) FONDOS PARA COFINANCIAR EL I+D DEDICADO AL BATA.
