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…
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…
