Monte Carlo water-equivalence study of two PRESAGE® formulations for proton beam dosimetry T Gorjiara, Z Kuncic, J Adamovics and C Baldock 2013 J. Phys.: Conf. Ser. 444 012090 PRESAGE® is a radiochromic solid dosimeter which shows promising potential for 3D proton beam dosimetry. Since an idea dosimeter should be water-equivalent, total depth dose distributions in two PRESAGE® formulations irra...

OBJECTIVE Development of a technique for treating whole-body skin using linear accelerator with electron beam energy of 6-MeV at a short treatment distance. MATERIAL AND METHODS The 6 MeV high dose rate total skin electron irradiation mode on a linear accelerator was used. Beam profiles and percentage depth doses in the patient plane were measured for different beam angulations. RESULTS At ...

The techniques of hydrogen loading in Pd are developed by many workers. And the states of hydrogen in Pd attract many interests because they might be related to the nuclear reactions. In this study, we have tried to observe optical phonon induced by hydrogen-hydrogen interactions in Pd using Raman spectroscopy. This measurement can be done for the sample completely sealed in a glass tube cuttin...

The performance of a polarizing beam splitter based on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated. The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave plates and the high-index half-wave plates with a central defect layer of air. The linear transmission properties of the polarizing beam splitter are numerically simulat...

PURPOSE To evaluate the uncertainties and characteristics of radiochromic film-based dosimetry system using the EBT3 model Gafchromic(®) film in therapy photon, electron and proton beams. MATERIAL AND METHODS EBT3 films were read using an EPSON Expression 10000XL/PRO scanner. They were irradiated in five beams, an Elekta SL25 6 MV and 18 MV photon beam, an IBA 100 MeV 5 × 5 cm(2) proton beam ...

The radioisotope (RI) beam facility is under construction at RIKEN. In the first phase, a new multi-stage acceleration system consisting of three ring cyclotrons with K=510 MeV, 980 MeV and 2500 MeV in each will be commissioned in 2005. It will boost the heavy-ion beams’ energies obtained by the existing K540-MeV ring cyclotron up to 350 MeV/nucleon. Intense RI beams are produced mostly via the...

ANKA is a 2.5 GeV synchrotron light source under construction at the Forschungszentrum Karlsruhe. The facility consists of a 53 MeV microtron, an injection line, a 500 MeV booster synchrotron, and the ejection line. The whole injector is being built as a turn key system by the industry (Danfysik, Denmark). The interface between the injector and the storage ring is the entrance of the injection ...

Total skin electron irradiation (TSEI) has been used as a treatment for mycosis fungoides. Our center has implemented a modified Stanford technique with six pairs of 6 MeV adjacent electron beams, incident perpendicularly on the patient who remains lying on a translational platform, at 200 cm from the source. The purpose of this study is to perform a dosimetric characterization of this techniqu...

A novel neutron irradiation facility at the Radiological Research Accelerator Facility (RARAF) has been developed to mimic the neutron radiation from an Improvised Nuclear Device (IND) at relevant distances (e.g. 1.5 km) from the epicenter. The neutron spectrum of this IND-like neutron irradiator was designed according to estimations of the Hiroshima neutron spectrum at 1.5 km. It is significan...
