Monte Carlo (MC) methods are increasingly being utilized to support several aspects of commissioning and clinical operation of ion beam therapy facilities. In this contribution two emerging areas of MC applications are outlined. The value of MC modeling to promote accurate treatment planning is addressed via examples of application of the FLUKA code to proton and carbon ion therapy at the Heide...

In view of the evaluation of the physics goals of a large Liquid Argon TPC, evolving from the ICARUS technology, we have studied the possibility of performing precision measurements on atmospheric neutrinos. For this purpose we have improved existing Monte Carlo neutrino event generators based on FLUKA and NUX by including the 3–flavor oscillation formalism and the numerical treatment of Earth ...

The gas electron multiplier (GEM) detector in combination with a solid converter has been widely used the field of neutron detection recent decades. Typically, sub-millimeter is an important indicator for detectors to satisfy many applications requiring high spatial resolution. This paper proposes novel method improve resolution ceramic GEM by adding stopping layer on top 10B4C converter. will ...

Abstract Renewed international interest in muon colliders motivates the continued investigation of impacts beam-induced background on detector performance. This continues effort initiated by Muon Accelerator Program and carried out until 2017. The from decays directly performance must be mitigated optimizing overall machine design, with particular attention paid to interface region. In order pr...

Heavy-ion collisions can be simulated by means of comprehensive approaches, to include the many different reaction mechanisms which may contribute. QMD models and their relativistic extensions are examples of these approaches based on Monte Carlo techniques. In this paper are shown some results obtained by coupling a new QMD code, which describes the fast stage of ion-ion collisions, to the eva...

With constructing and operating the third generation facilities such as SPring-8, however, high energy synchrotron radiation of extremely high intense is available, and high accuracy should be required in the shielding and safety design for the beamline of synchrotron radiation. Furthermore, the middle size facilities, such as CLS (Canadian Light Source), are now under construction and the opti...

Interest in phase contrast imaging methods based on electromagnetic wave coherence has increased significantly recently, particularly at X-ray energies. This is giving rise to a demand for effective simulation methods. Coherent imaging approaches are usually based on wave optics, which require significant computational resources, particularly for producing 2D images. Monte Carlo (MC) methods, u...

The LHC collimation system is installed and commissioned in different phases, following the natural evolution of the LHC performance. To improve cleaning efficiency towards the end of the low beta squeeze at 7TeV, and in stable physics conditions, it is foreseen to complement the 30 highly robust Phase I secondary collimators with low impedance Phase II collimators. At this stage, their design ...

Samples of soil, water, aluminum, copper and iron were irradiated in the stray radiation field generated by the interaction of a 28.5 GeV electron beam in a copper-dump in the Beam Dump East facility at SLAC. The specific activity induced in the samples was measured by gamma spectroscopy and other techniques. In addition, the isotope production in the samples was calculated with detailed Monte ...

We present here a comparison of interaction models commonly used for simulating cosmic ray shower development in the atmosphere at energies greater than 1 TeV. The implementations of these models in CORSIKA and the FLUKA transport and interaction code are relevant for extensive air shower experiments, neutrino telescopes, and gamma-ray surfacebased detectors. We compare the pion, kaon, charmed ...
