CERN openlab Whitepaper on Future IT Challenges in Scientific Research
This whitepaper describes the major IT challenges in scientific research at CERN and several other European and international research laboratories and projects. Each challenge is exemplified through a set of concrete use cases drawn from the requirements of large-scale scientific programs. The paper is based on contributions from many researchers and IT experts of the participating laboratories and also input from the existing CERN openlab industrial sponsors. The views expressed in this document are those of the individual contributors and do not necessarily reflect the view of their organisations and/or affiliates

Strategies of development and maintenance in supervision, control, synchronization, data acquisition and processing in light sources
Programa Oficial de Doutoramento en Tecnoloxías da Información e as Comunicacións. 5032V01[Resumo]
Os aceleradores de partículas e fontes de luz sincrotrón, evolucionan constantemente para estar
na vangarda da tecnoloxía, levando os límites cada vez mais lonxe para explorar novos
dominios e universos. Os sistemas de control son unha parte crucial desas instalacións
científicas e buscan logra-la flexibilidade de manobra para poder facer experimentos moi
variados, con configuracións diferentes que engloban moitos tipos de detectores,
procedementos, mostras a estudar e contornas.
As propostas de experimento son cada vez máis ambiciosas e van sempre un paso por diante
do establecido. Precísanse detectores cada volta máis rápidos e eficientes, con máis ancho de
banda e con máis resolución. Tamén é importante a operación simultánea de varios detectores
tanto escalares como mono ou bidimensionáis, con mecanismos de sincronización de precisión
que integren as singularidades de cada un.
Este traballo estuda as solucións existentes no campo dos sistemas de control e adquisición de
datos nos aceleradores de partículas e fontes de luz e raios X, ó tempo que explora novos
requisitos e retos no que respecta á sincronización e velocidade de adquisición de datos para
novos experimentos, a optimización do deseño, soporte, xestión de servizos e custos de
operación. Tamén se estudan diferentes solucións adaptadas a cada contorna.[Resumen] Los aceleradores de partículas y fuentes de luz sincrotrón, evolucionan constantemente para
estar en la vanguardia de la tecnología, y poder explorar nuevos dominios. Los sistemas de
control son una parte fundamental de esas instalaciones científicas y buscan lograr la máxima
flexibilidad para poder llevar a cabo experimentos más variados, con configuraciones
diferentes que engloban varios tipos de detectores, procedimientos, muestras a estudiar y
entornos.
Los experimentos se proponen cada vez más ambiciosos y en ocasiones más allá de los límites
establecidos. Se necesitan detectores cada vez más rápidos y eficientes, con más resolución y
ancho de banda, que puedan sincronizarse simultáneamente con otros detectores tanto escalares
como mono y bidimensionales, integrando las singularidades de cada uno y homogeneizando
la adquisición de datos.
Este trabajo estudia los sistemas de control y adquisición de datos de aceleradores de partículas
y fuentes de luz y rayos X, y explora nuevos requisitos y retos en lo que respecta a la
sincronización y velocidad de adquisición de datos, optimización y costo-eficiencia en el
diseño, operación soporte, mantenimiento y gestión de servicios. También se estudian diferentes soluciones adaptadas a cada entorno.[Abstract]
Particle accelerators and photon sources are constantly evolving, attaining the cutting-edge
technologies to push the limits forward and explore new domains. The control systems are a crucial
part of these installations and are required to provide flexible solutions to the new
challenging experiments, with different kinds of detectors, setups, sample environments and
procedures.
Experiment proposals are more and more ambitious at each call and go often a step beyond the
capabilities of the instrumentation. Detectors shall be faster, with higher efficiency,
more resolution, more bandwidth and able to synchronize with other detectors of all kinds; scalars,
one or two-dimensional, taking into account their singularities and homogenizing the
data acquisition.
This work examines the control and data acquisition systems for particle accelerators and X- ray /
light sources and explores new requirements and challenges regarding synchronization and data
acquisition bandwidth, optimization and cost-efficiency in the design / operation / support. It
also studies different solutions depending on the environment
Introduction to the Analysis of Low-Frequency Gravitational Wave Data
The space-based gravitational wave detector LISA will observe in the
low-frequency gravitational-wave band (0.1 mHz up to 1 Hz). LISA will search
for a variety of expected signals, and when it detects a signal it will have to
determine a number of parameters, such as the location of the source on the sky
and the signal's polarisation. This requires pattern-matching, called matched
filtering, which uses the best available theoretical predictions about the
characteristics of waveforms. All the estimates of the sensitivity of LISA to
various sources assume that the data analysis is done in the optimum way.
Because these techniques are unfamiliar to many young physicists, I use the
first part of this lecture to give a very basic introduction to time-series
data analysis, including matched filtering. The second part of the lecture
applies these techniques to LISA, showing how estimates of LISA's sensitivity
can be made, and briefly commenting on aspects of the signal-analysis problem
that are special to LISA.Comment: 20 page
