Parallel-plate chambers as radiation-hard detectors for time-based beam diagnostics in carbon-ion radiotherapy
Na Hye Kwon, Sung Woon Choi, Soo Rim Han +13
Accurate range verification of carbon ion beams is critical for the precision and safety of charged particle radiotherapy. In this study, we evaluated the feasibility of using a pa…
Investigation of the Production Mechanism in p(3.5 GeV)+p Collisions
R. Abou Yassine, O. Arnold, M. Becker +88
The production of hyperons in proton proton collisions at a beam kinetic energy of 3.5 GeV impinging on a liquid hydrogen target was investigated using data collected with th…
Production of hydrogen isotopes and charged pions in p (3.5 GeV) + Nb reactions
R. Abou Yassine, O. Arnold, M. Becker +85
The double differential production cross sections, , for hydrogen isotopes and charged pions in the reaction of p + Nb at 3.5 GeV proton beam energy have been measured b…
Outdoor Systems Performace and Upgrade
L. Lopes, S. Andringa, P. Assis +17
Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort having installed several systems…
An RPC-PET brain scanner demonstrator: first results
Paulo Fonte, Luís Lopes, Rui Alves +19
We present first results from a Positron Emission Tomography (PET) scanner demonstrator based on Resistive Plate Chambers and specialized for brain imaging. The device features a 3…
MARTA: A high-energy cosmic-ray detector concept with high-accuracy muon measurement
P. Abreu, S. Andringa, P. Assis +42
A new concept for the direct measurement of muons in air showers is presented. The concept is based on resistive plate chambers (RPCs), which can directly measure muons with very g…
Autonomous RPCs for a Cosmic Ray ground array
Pedro Assis, Alberto Blanco, Nuno Carolino +15
We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA…
Outdoor Field Experience with Autonomous RPC Based Stations
L. Lopes, P. Assis, A. Blanco +12
In the last two decades Resistive Plate Chambers were employed in the Cosmic Ray Experiments COVER-PLASTEX and ARGO/YBJ. In both experiments the detectors were housed indoors, like…
High Resolution RPC's for Large TOF Systems
P. Fonte, R. Ferreira Marques, J. Pinhao +2
Here we report on a particular type of RPC that presents up to 99% efficiency for minimum ionizing particles and a very sharp time resolution, below 50 ps sigma in the most optimiz…
