We announce the forthcoming public release of Version 1.1 of MGGPOD, a user-friendly suite of Monte Carlo codes built around the widely used GEANT (Version 3.21) package. MGGPOD is capable of simulating ab initio the physical processes relevant for the production of instrumental backgrounds. These processes include the build-up and delayed decay of radioactive isotopes as well as the prompt de-...

A key assumption in the reconstruction of extensive air showers using the air fluorescence technique is the hypothesis that fluorescence is proportional to energy deposition at all depths in the shower. This ansatz, along with the supposition that particle distribution and energy loss can be well modeled by modern shower simulation software, must be thoroughly verified in order to validate the ...

We present a three-dimensional calculation of atmospheric neutrino fluxes using accurate models of the geomagnetic field, hadronic interactions, tracking and decays. Results are presented for the Super-Kamiokande (SK) and Sudbury Neutrino Observatory (SNO) sites using the GEANT-FLUKA hadronic code. We make a comparison with previous one-dimensional calculations and other three-dimensional resul...

Thread-parallelisation and single-instruction multiple data (SIMD) ”vectorisation” of software components in HEP computing has become a necessity to fully benefit from current and future computing hardware. In this context, the Geant-Vector/GPU simulation project aims to re-engineer current software for the simulation of the passage of particles through detectors in order to increase the overal...

We have performed a detailed Monte Carlo (MC) simulation for the Advanced Thin Ionization Calorimeter (ATIC) detector using the MC code FLUKA-2006 which is capable of simulating particles up to 10 PeV. The ATIC detector has completed two successful balloon flights from McMurdo, Antarctica lasting a total of more than 35 days. ATIC is designed as a multiple, long duration balloon flight, investi...

The availability of modern telecommunication and information technologies has a direct influence on the evolution of all aspects of the information society. The needs of science and research community in Poland were the reason for establishing a dedicated programme for the development of the information infrastructure in Poland some years ago. A programme called „The Development of the Informat...

Nurzia, G., Scrimaglio, R., Spataro, B., Zirilli, F. The use of a syncytium model of the crystalline lens of the human eye to study the light flashes seen by astronauts. Radiat. Res. A syncytium model to study some electrical properties of the eye is proposed in the attempt to explain the phenomenon of anomalous Light Flashes (LF) perceived by astronauts in orbit. The crystalline lens is modell...

The routine operation and maintenance of nuclear facilities generate quantities of radioactive material in many different matrices that are packed in many different sized containers. The waste is often packaged in large containers, such as 220 l drums, because process operators find drums more economical to handle than small containers. Based on regulations, the radioactivity and the radionucli...

High energy physics is replete with multi-dimensional information which is often poorly represented by the two dimensions of presentation slides and print media. Past efforts to disseminate such information to a wider audience have failed for a number of reasons, including a lack of standards which are easy to implement and have broad support. Adobe's Portable Document Format (PDF) has in recen...
