Hadron therapy hospital centers have become wide spread in the world during the last decade. These centers were created mainly on basis of the cycling accelerators such as cyclotrons and synchrotrons. Now there are several proposals of the proton centers on the basis of linear accelerators. In this report we discuss features, advantages and disadvantages of hadron therapy centers on the basis o...

Abstract Three spare modules of the ATLAS Tile Calorimeter were exposed to test beams from Super Proton Synchrotron accelerator at CERN in 2017. The detector’s measurements energy response and resolution positive pions kaons, protons with energies ranging 16 30 GeV are reported. results have uncertainties a few percent. They compared predictions Geant4-based simulation program used estimate det...

Introduction: Proton therapy is newer therapeutic method for early stage breast cancer. Proton beams release most of their energy in the Bragg peak and then will be a rapid decline in their end. When protons interact with matter, produce secondary particles like neutrons and gammas, and these unwanted radiation has no beneficial effect and also is believed to increase the risk ...

BACKGROUND In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness. METHODS In this study, we used Monte Carlo method-based Geant4 toolkit to ...

Over the last several years, the Target Normal Sheath Acceleration (TNSA) mechanism in solid density plasmas produced by a laser pulse has achieved proton energies up to 10’s of MeV and quasi-monoenergetic beams at lower energies. Although solid-target experiments have demonstrated high-charge and low-emittance proton beams, little work has been done with gaseous targets which in principle can ...

The delivery of accurate proton dose for clinical trials requires that the appropriate conversion function from Hounsfield unit (HU) to relative linear stopping power (RLSP) be used in proton treatment planning systems (TPS). One way of verifying that the TPS is calculating the correct dose is an end-to-end test using an anthropomorphic phantom containing tissue equivalent materials and dosimet...

Spallation sources dedicated to neutron scattering experiments, as well as multi-purpose facilities serving several applications call for pulsed mode operation of a high intensity proton linac. There is general agreement on the superconducting technology for the high-energy part, which offers some advantages, like higher gradient capabilities or operational costs reduction, as compared to room-...

Proton radiography or microscopy is a novel technique for probing the interior of dense objects in dynamic experiments by mono-energetic beams of GeV-energy protons. A special system of magnetic lenses is employed for imaging and aberrations correction. Using this technique, one can measure areal density of a thick sample with sub-percent accuracy. The spatial resolution is a few micrometers ov...

A new luminescence beam profile monitor is realized in the polarized hydrogen gas jet target at the Relativistic Heavy Ion Collider (RHIC) facility. In addition to the spin polarization of the proton beam being routinely measured by the hydrogen gas jet, the luminescence produced by beam-hydrogen excitation leads to a strong Balmer series lines emission. A selected hydrogen Balmer line is spect...

In context of the LIGHT project (Laser-Ion Generation, Handling and Transport) [1], studies on the capability of a solenoidal magnetic field to collimate and transport laser-accelerated proton beams were carried out. Results of preliminary particle-in-cell simulations [2] and experiments at the PHELIX laser facility [1, 3] demand a detailed analysis of the space-charge influence. Therefore, the...
