Abstract The design study of the AGATA array began with development simulation code using GEANT4. latter played a key part in final and provided cost effective solution for early tracking algorithm. has since been maintained developed by collaboration to provide more realistic simulations, reaction chambers, ancillary detectors surrounding mechanical structures completing entire setup.

The Geometry modeller is a key component of the Geant4 toolkit [1,2]. It has been designed to exploit at the best the features provided by the Geant4 simulation toolkit, allowing the description of the geometrical structure of complex detectors in a natural way, ranging from a few up to hundreds of thousands volumes of the LHC experiments, as well as human phantoms for medical applications or d...

Stereo mini-jet cells will be indispensable components of a future ee linear collider central tracker such as JLC-CDC. There is, however, no official Geant4 solid available at present to describe such geometrical objects, which had been a major obstacle for us to develop a full Geant4-based simulator with stereo cells built in. We have thus extended Geant4 to include a new solid (TwistedTubs), ...

The Visualization System of GEANT4 is an interface between the simulation kernel and the graphics system. In itself it defines only the functionality required by the kernel and the GEANT4 user. It contains an abstract interface to which an installer may fit his or her favourite graphics system; concrete interfaces to some graphics systems come ready-to-use with the GEANT4 toolkit. Commands to t...

In order to assess the feasibility of spallation driven fission and transmutation, we have simulated proton induced neutron production using GEANT4, initially benchmarking our simulations against published experimental neutron spectra produced from a thick lead target bombarded with 0.5 and 1.5 GeV protons. The Bertini and INCL models available in GEANT4, coupled with the high precision (HP) ne...

A binary formatwith lists of particle state information, for interchanging particles between variousMonte Carlo simulation applications, is presented. Portable C code for file manipulation is made available to the scientific community, along with converters and plugins for several popular simulation packages.

BACKGROUND The Monte Carlo code GEANT4 was used to implement first steps towards a treatment planning program for fast-neutron therapy at the FRM II research reactor in Garching, Germany. Depth dose curves were calculated inside a water phantom using measured primary neutron and simulated primary photon spectra and compared with depth dose curves measured earlier. The calculations were performe...

Introduction: Spatial dose distribution around the radionuclides sources is required for optimized treatment planning in radioimmunotherapy. At present, the main source of data for cellular dosimetry is the s-values provided by MIRD. However, the MIRD s-values have been calculated based on analytical formula in which no electrons straggling is taken to account. In this study, we used Geant4-DNA...

Therapeutic irradiation with protons and ions is advantageous over radiotherapy with photons due to its favorable dose deposition. Additionally, ion beams provide a higher relative biological effectiveness than photons. For this reason, an improved treatment of deep-seated tumors is achieved and normal tissue is spared. However, small deviations from the treatment plan can have a large impact o...
