Fast Beam Condition Monitor for CMS: performance and upgrade

The CMS beam and radiation monitoring subsystem BCM1F (Fast Beam Condition Monitor) consists of 8 individual diamond sensors situated around the beam pipe within the pixel detector volume, for the purpose of fast bunch-by-bunch monitoring of beam background and collision products. In addition, effort is ongoing to use BCM1F as an online luminosity monitor. BCM1F will be running whenever there is beam in LHC, and its data acquisition is independent from the data acquisition of the CMS detector, hence it delivers luminosity even when CMS is not taking data. A report is given on the performance of BCM1F during LHC run I, including results of the van der Meer scan and on-line luminosity monitoring done in 2012. In order to match the requirements due to higher luminosity and 25 ns bunch spacing, several changes to the system must be implemented during the upcoming shutdown, including upgraded electronics and precise gain monitoring. First results from Run II preparation are shown.Comment: 10 pages, 8 figures. To be published in NIM A as proceedings for the 9th Hiroshima Symposium on Semiconductor Tracking Detectors (2013

Measurement of the very rare K+→π+ννˉK^+ \to \pi^+ \nu \bar\nu decay

The decay K+→π+νν¯ , with a very precisely predicted branching ratio of less than 10−10 , is among the best processes to reveal indirect effects of new physics. The NA62 experiment at CERN SPS is designed to study the K+→π+νν¯ decay and to measure its branching ratio using a decay-in-flight technique. NA62 took data in 2016, 2017 and 2018, reaching the sensitivity of the Standard Model for the K+→π+νν¯ decay by the analysis of the 2016 and 2017 data, and providing the most precise measurement of the branching ratio to date by the analysis of the 2018 data. This measurement is also used to set limits on BR(K+→π+X ), where X is a scalar or pseudo-scalar particle. The final result of the BR(K+→π+νν¯ ) measurement and its interpretation in terms of the K+→π+X decay from the analysis of the full 2016-2018 data set is presented, and future plans and prospects are reviewed

Geoelectrical characterization of a site with hydrocarbon contamination caused by pipeline leakage

El método Sondeo Eléctrico Vertical (SEV) es ampliamente utilizado en estudios de impacto ambiental incluyendo el caso de contaminación por hidrocarburos. En este trabajo se presentan los resultados de la caracterización geoeléctrica de un sitio contaminado por hidrocarburos relacionado con una fuga en línea de ducto. El estudio geoeléctrico fue realizado utilizando el método SEV en la variante de tomografía, realizándose una interpretación 2D de los datos observados. Seis perfiles paralelos de SEV fueron medidos y presentados sus resultados en secciones y mapas. Se determinó un modelo estratificado que incluye acuitardo y acuífero. Aunque el grado de contaminación en este sitio es bajo fue posible localizar dos zonas contaminadas dentro del acuífero. El acuífero y el acuitardo fueron caracterizados con base en su resistividad, contenido de arcilla, porosidad y capacidad de intercambio catiónico. Los valores de resistividad fueron recalculados a valores de parámetros petrofísicos utilizando un algoritmo de inversión que toma en cuenta la salinidad del agua de poro. En zonas no contaminadas los parámetros petrofísicos estimados a partir de datos de resistividad presentan valores cercanos a los reales, mientras que en zonas contaminadas se obtienen valores anómalos. Efectos similares de la influencia contaminación sobre los parámetros petrofísicos fueron encontrados en laboratorio realizando mediciones de resistividad en muestras de arena limpia y contaminada

Fast beam conditions monitor (BCM1F) for CMS

The CMS Beam Conditions and Radiation Monitoring System (BRM) [1] is composed of different subsystems that perform monitoring of, as well as providing the CMS detector protection from, adverse beam conditions inside and around the CMS experiment. This paper presents the Fast Beam Conditions Monitoring subsystem (BCM1F), which is designed for fast flux monitoring based on bunch by bunch measurements of both beam halo and collision product contributions from the LHC beam. The BCM1F is located inside the CMS pixel detector volume close to the beam-pipe and provides real-time information. The detector uses sCVD (single-crystal Chemical Vapor Deposition) diamond sensors and radiation hard front-end electronics, along with an analog optical readout of the signals

Estimation of soil petrophysical parameters based on electrical resistivity values obtained from lab and in-field measurements

El conocimiento de los parámetros petrofísicos del suelo es muy útil para la agricultura y análisis de impacto ambiental. Por lo tanto, es importante desarrollar técnicas y metodologías que ayuden a obtener mapas petrofísicos del suelo de manera rápida y económica. Este trabajo muestra dos técnicas para la estimación del contenido de arcilla, porosidad y capacidad de intercambio catiónico a partir de mediciones eléctricas. La primera, basada en mediciones de resistividad del suelo (SRM) realizadas en laboratorio; la segunda técnica, ERT&WRM, mediante la aplicación de Tomografía de Resistividad Eléctrica (ERT) y mediciones en campo de resistividad en muestras de agua subterránea (WRM). Se realizó un estudio geoeléctrico en un sitio areno-limoso y los resultados alcanzados fueron comparado con los obtenidos mediante la técnica de análisis textural de Bouyoucos. La técnica SRM mostró ser más precisa y menos productiva que la técnica ERT&WRM. Los resultados obtenidos proponen una nueva aplicación de los métodos geoeléctricos en estudios de agricultura precisa, tanto para análisis de muestras de suelo en laboratorio utilizando la técnica SRM como para evaluar grandes extensiones de suelo agrícola utilizando la técnica ERT&WRM. doi: https://doi.org/10.22201/igeof.00167169p.2012.51.1.14

The Embedded Local Monitor Board upgrade proposals

The Embedded Local Monitor Board (ELMB) is a microcontroller based plug-in module usingthe CANopen communication protocol. It has been widely used in LHC systems and experimentsfor slow-control and monitoring purposes, providing multiple, galvanically isolated analog inputs,and multiple digital inputs and outputs. While the module showed excellent performance in thepast 15 years, a new design is deemed necessary due to the obsolescence of some components ofthe existing ELMB and the higher radiation tolerance required for the planned HL-LHC upgrade.Three development paths, one fully backward compatible and two conceptually different solutionswith different levels of radiation tolerance are presented

Continuous Integration for the Software and the Firmware of the new ATLAS Muon-Central-Trigger-Processor Interface (MUCTPI)

The new Muon-Central-Trigger-Processor Interface (MUCTPI) is part of the upgrade of the ATLAS Level-1 trigger system for run 3 of the Large Hadron Collider at CERN. The new MUCTPI has three high-end FPGAs and one System-on-Chip (SoC). The FPGAs receive and process muon candidate information arriving on 208 high-speed optical serial links. Processed trigger information and summary data are sent to other parts of the trigger and the data acquisition. The SoC controls, configures and monitors the hardware and the operation of the MUCTPI. The FPGA part of the SoC provides communication with the processing FPGAs, while the processor system runs software for communication with the run control system of the ATLAS experiment. All software necessary to run the MUCTPI, including operating system and run control software is being built using continuous integration. CentOS Linux, cross-compilation and the existing framework for building of the ATLAS trigger and data acquisition (TDAQ) software are being used in order to deploy the TDAQ software directly on the SoC. After the successful use of continuous integration of the software, also the firmware is being built using that scheme. This paper describes the advantages of the use of continuous integration, our experience, as well as the difficulties that needed to be overcome

Integration and commissioning of the ATLAS Muon-to-Central-Trigger-Processor Interface for Run-3

The Muon-to-Central Trigger Processor Interface (MUCTPI) was completely redesigned as part of the ATLAS Level-1 trigger upgrade for Run 3 of the Large Hadron Collider. The new system is implemented as a single AdvancedTCA module, using three large state-of-the-art FPGAs and high-density fibre-optic modules. 208 high speed links receive trigger information from the muon trigger detectors, while 60 links are used to send processed trigger information to the L1 Topological Trigger Processor and the Central Trigger Processor. Extensive integration tests with all input and output systems have shown that the data transfer is stable and reliable. We present results from integration tests with connected sub-systems as well as commissioning of the MUCTPI in the ATLAS experiment
