Intelligent problem solving in process control of an event filter cluster for a particle physics experiment

Expert Systems with Applications, 2011
Modern particle physics experiments observing collisions of particle beams generate large amounts of data. Complex trigger and data acquisition systems are built to select on line the most interesting events and write them to persistent storage. The final stage of this selection process nowadays often happens on large computer clusters.

Physical characterization of aerosol particles during the Chinese New Year’s firework events

Atmospheric Environment, 2010
Abstract Measurements for particles 10 nm to 10 μm were taken using a Wide-range Particle Spectrometer during the Chinese New Year (CNY) celebrations in 2009 in Shanghai, China. These celebrations provided an opportunity to study the number concentration and size distribution of particles in an especial atmospheric pollution situation due to firework

Grid-enabled particle physics event analysis: experiences using a 10 Gb, high-latency network for a high-energy physics application

Future Generation Computer Systems, 2003
This paper examines issues encountered attempting to exploit a high-bandwidth, high-latency link in support of a high-energy physics (HEP) analysis application. The primary issue was that the TCP additive increase/multiplicative decrease (AIMD) algorithm is not suitable for "long fat networks". While this is a known problem, the magnitude of the impact

Process Control of an Event Filter Farm for a Particle Physics Experiment Based on Expert System Technology

2007
Modern particle physics experiments observing collisions of particle beams generate large amounts of data. Large trigger and data acquisition systems are built to select on-line the most interesting events and write them to persistent storage. The final stage of this selection process nowadays often happens on large computer farms.

Signature-Change Events, Trans-Planckian Physics and Quasi-Particle Amplification in Bose-Einstein Condensates

Quantum-Atom Optics Downunder, 2007
We explore signature-changing emergent geometries in a BEC; specifically analogues of signature change from Euclidean to Lorentzian regions. In our BEC-based analogue model, signature change is achieved via a change in atomic interactions from repulsive to attractive. The particle production resulting from a finite-duration Euclidean-signature event is

THEORETICAL INVESTIGATION OF PULSE SHAPES OF DOUBLE BETA EVENTS IN A 76Ge DETECTOR, THEIR DEPENDENCE ON PARTICLE PHYSICS PARAMETERS, AND THEIR SEPARABILITY FROM BACKGROUND GAMMA EVENTS

Modern Physics Letters A, 2006
For the first time the expected pulse shapes to be observed for neutrinoless double beta events in a big 76 Ge detector have been calculated starting from their Monte Carlo calculated time history and spatial energy distribution. It is shown that with the spatial resolution of a large size Ge detector for the majority of 0νββ events it is not possible

Validation of electromagnetic and hadronic physical processes in the interaction of a proton beam with matter: A Solar Particle Events case study with an Al slab

Advances in Space Research, 2017
Abstract In the study of the effectiveness of shielding materials against radiations, one of the main steps concerns with the validation of models describing the interaction processes of the radiation of interest with the material chosen for the shielding.

The FLUKA code, galactic cosmic ray and Solar Energetic Particle events: From fundamental physics to space radiation and commercial aircraft doses

2008 IEEE Nuclear Science Symposium Conference Record, 2008
The FLUKA Monte Carlo code has been widely applied and benchmarked in recent years to problems related to Galactic Cosmic Rays (GCR) and Solar Energetic Particle (SEP) events. Applications range from fundamental cosmic ray and neutrino physics, to doses to commercial aircraft and space radiation issues in low orbit or in deep space. The main results of
