Proyecto cooperativo entre asignaturas de Ingeniería Electrónica

[EN] This article proposes a teaching innovation based on a common thread between the different subjects involved in the third year of the Degree in Industrial Electronic Engineering at the University of Valencia. For this purpose, a common multidisciplinary and cooperative project has been designed that includes concepts taught in all the subjects of the course. The teaching project consists of using an air levitator prototype as a reference platform on which different activities have been proposed and carried out, independent of each other, but which are directly related to the levitation system. As a main result, it is expected that students have a global perspective of Electronic Engineering and understand that the concepts taught in the different subjects of the course are interrelated and complementary.[ES] La innovación docente propuesta en el presente artículo tiene como objetivo el desarrollo de un hilo conductor entre las diferentes asignaturas involucradas en el tercer curso del Grado en Ingeniería Electrónica Industrial de la Universitat de València. Para ello, se ha diseñado un proyecto común multidisciplinar y cooperativo que engloba conceptos impartidos en todas las materias del curso. El proyecto docente consiste en utilizar un prototipo de levitador de aire como plataforma de referencia sobre la que se han propuesto y llevado a cabo diferentes actividades que podrían analizarse de forma independiente, pero que aquí se han integrado mostrando que todas contribuyen a diseñar y explicar el funcionamiento del sistema de levitación. Como principal resultado, se espera que los alumnos tengan una perspectiva global de la Ingeniería Electrónica y entiendan que los conceptos impartidos en las diferentes materias del curso están interrelacionados y son complementarios.Este trabajo ha sido financiado por la Universitat de València a través del proyecto de innovación docente UV-SFPIE_PID-2077390.Girbés Juan, V.; Esperante Pereira, D.; Amorós López, J.; Espí Huerta, J.; Maset Sancho, E.; Ramírez Muñoz, D.; Calvo Díaz-Aldagalan, D....

Performance of a spaghetti calorimeter prototype with tungsten absorber and garnet crystal fibres

A spaghetti calorimeter (SPACAL) prototype with scintillating crystal fibres was assembled and tested with electron beams of energy from 1 to 5 GeV. The prototype comprised radiation-hard Cerium-doped Gd$_3$Al$_2$Ga$_3$O$_{12}$ (GAGG:Ce) and Y$_3$Al$_5$O$_{12}$ (YAG:Ce) embedded in a pure tungsten absorber. The energy resolution was studied as a function of the incidence angle of the beam and found to be of the order of $10\% / \sqrt{E} \oplus1\%$, in line with the LHCb Shashlik technology. The time resolution was measured with metal channel dynodes photomultipliers placed in contact with the fibres or coupled via a light guide, additionally testing an optical tape to glue the components. Time resolution of a few tens of picosecond was achieved for all the energies reaching down to (18.5 $\pm$ 0.2) ps at 5 GeV.Comment: 14 pages, 8 figures, published on NIM

PACIFIC: SiPM readout ASIC for LHCb upgrade

International audienceA new 64-channel mixed-signal ASIC is presented: PACIFIC. It was developed in TSMC 130 nm CMOS technology for the readout of the Scintillating Fibre Tracker, as a part of the LHCb upgrade. This detector is based on 250  μ m scintillating fibers readout by custom designed 128-channel silicon photomultiplier arrays. It will cover a total area of 340 m 2 , distributed over the 12 planes that compose it. The sensors are connected directly to PACIFIC without any interface components. The ASIC acquires the current pulses using a current conveyor. A fast double pole-zero cancellation shaper is used to minimize spillover. The charge is then collected using gated integrators, with a twofold interleaved scheme to minimize dead time. The resulting voltage level is digitized with a configurable 2 bit non-linear flash ADC. The output is a 320 Mbps differential signal produced by the serializers, which gather the results from four adjacent channels
