FLUKA (FLUktuierende KAskade) is a fully integrated Monte Carlo simulation package for the interaction and transport of particles and nuclei in matter. [2] [3] [4] [5] FLUKA has many applications in particle physics, high energy experimental physics and engineering, shielding, detector and telescope design, cosmic ray studies, [6] dosimetry, [7] medical physics, radiobiology. A recent line of development concerns hadron therapy. [8] [9]
It is the standard tool used in radiation protection studies in the CERN particle accelerator laboratory. [10] [11] FLUKA software code is used by Epcard, which is a software program for simulating radiation exposure on airline flights. [12]
Monte Carlo methods, or Monte Carlo experiments, are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches. Monte Carlo methods are mainly used in three problem classes: optimization, numerical integration, and generating draws from a probability distribution.
A linear particle accelerator is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline. The principles for such machines were proposed by Gustav Ising in 1924, while the first machine that worked was constructed by Rolf Widerøe in 1928 at the RWTH Aachen University. Linacs have many applications: they generate X-rays and high energy electrons for medicinal purposes in radiation therapy, serve as particle injectors for higher-energy accelerators, and are used directly to achieve the highest kinetic energy for light particles for particle physics.
ISABELLE was a 200+200 GeV proton–proton colliding beam particle accelerator partially built by the United States government at Brookhaven National Laboratory in Upton, New York, before it was cancelled in July, 1983.
Geant4 is a platform for "the simulation of the passage of particles through matter" using Monte Carlo methods. It is the successor of the GEANT series of software toolkits developed by The Geant4 Collaboration, and the first to use object oriented programming. Its development, maintenance and user support are taken care by the international Geant4 Collaboration. Application areas include high energy physics and nuclear experiments, accelerator and space physics studies. The software is used by a number of research projects around the world.
ROOT is an object-oriented computer program and library developed by CERN. It was originally designed for particle physics data analysis and contains several features specific to the field, but it is also used in other applications such as astronomy and data mining. The latest minor release is 6.28, as of 2023-02-03.
GEANT is the name of a series of simulation software designed to describe the passage of elementary particles through matter, using Monte Carlo methods. The name is an acronym formed from "GEometry ANd Tracking". Originally developed at CERN for high energy physics experiments, GEANT-3 has been used in many other fields.
Monte Carlo N-Particle Transport (MCNP) is a general-purpose, continuous-energy, generalized-geometry, time-dependent, Monte Carlo radiation transport code designed to track many particle types over broad ranges of energies and is developed by Los Alamos National Laboratory. Specific areas of application include, but are not limited to, radiation protection and dosimetry, radiation shielding, radiography, medical physics, nuclear criticality safety, detector design and analysis, nuclear oil well logging, accelerator target design, fission and fusion reactor design, decontamination and decommissioning. The code treats an arbitrary three-dimensional configuration of materials in geometric cells bounded by first- and second-degree surfaces and fourth-degree elliptical tori.
In particle physics, the parton model is a model of hadrons, such as protons and neutrons, proposed by Richard Feynman. It is useful for interpreting the cascades of radiation produced from quantum chromodynamics (QCD) processes and interactions in high-energy particle collisions.
The EGS computer code system is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several hundreds of GeV. It originated at SLAC but National Research Council of Canada and KEK have been involved in its development since the early 80s.
UrQMD is a fully integrated Monte Carlo simulation package for Proton+Proton, Proton+nucleus and nucleus+nucleus interactions. UrQMD has many applications in particle physics, high energy experimental physics and engineering, shielding, detector design, cosmic ray studies, and medical physics.
Donald Hill Perkins was a British physicist and an emeritus professor at the University of Oxford. He achieved great success in the field of particle physics and was also known for his books.
EPCARD is a software program that calculates radiation exposure of aircrews. The software code is based on the FLUKA transport code. EPCARD allows calculation of a simulated dose from most important components of penetrating cosmic radiation on any aviation route and for any flight profile at altitudes from 5 to 25 km.
Pencil beam scanning is the practice of steering a beam of radiation or charged particles across an object. It is often used in proton therapy, to reduce unnecessary radiation exposure to surrounding non-cancerous cells.
The Harwell Synchrocyclotron was a particle accelerator based at the Atomic Energy Research Establishment campus near Harwell, Oxfordshire. Construction of the accelerator began in 1946 and it was completed in 1949. The machine was of the synchrocyclotron design, with a 1.62T magnet of diameter 110" (2.8m) allowing protons to be accelerated to energies of 160-175MeV. Accelerator physicist John Adams, who later went on to lead design of CERN's SPS, was instrumental in the design and construction of this machine. Its main function was basic nuclear and particle physics research, with a focus on proton-proton and proton-neutron scattering.
Xie George Xu was the Edward E. Hood Chair Professor of Engineering at Rensselaer Polytechnic Institute (RPI), Troy, New York, United States, before he relocated in 2020 to China and joined the faculty of the University of Science and Technology of China.
Vinod Chandrasinh Chohan was a Tanzanian-born accelerator specialist and engineer. He was a Senior Staff Member at CERN for nearly 40 years.
The Synchro-Cyclotron, or Synchrocyclotron (SC), built in 1957, was CERN’s first accelerator. It was 15.7 metres (52 ft) in circumference and provided beams for CERN's first experiments in particle and nuclear physics. It accelerated particles to energies up to 600 MeV. The foundation stone of CERN was laid at the site of the Synchrocyclotron by the first Director-General of CERN, Felix Bloch. After its remarkably long 33 years of service time, the SC was decommissioned in 1990. Nowadays it accepts visitors as an exhibition area in CERN.
Maria Fidecaro (1930-2023) was an Italian experimental physicist with a focus on particle physics. She has spent most of her career at CERN, where she after retirement had the status of honorary member of the personnel.
Proton computed tomography (pCT), or proton CT, is an imaging modality first proposed by Cormack in 1963 and initial experiment explorations identified several advantages over conventional X-ray CT (xCT). However, particle interactions such as multiple Coulomb scattering (MCS) and (in)elastic nuclear scattering events deflect the proton trajectory, resulting in nonlinear paths which can only be approximated via statistical assumptions, leading to lower spatial resolution than X-ray tomography. Further experiments were largely abandoned until the advent of proton radiation therapy in the 1990s which renewed interest in the topic due to the potential benefits of imaging and treating patients with the same particle.
