An RPC-PET brain scanner demonstrator: first results
Paulo Fonte, LuÃs 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…
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…
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +447
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Au…
A Large-Area RPC Detector for Muography
João Saraiva, Carlos Alemparte, Daniel Belver +5
A muon telescope equipped with four Resistive Plate Chambers of 2 m per plane was tested with the muon scattering tomography technique. The telescope was operated during seve…
Measurement of the cosmic ray spectrum above eV using inclined events detected with the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +461
A measurement of the cosmic-ray spectrum for energies exceeding eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\…
Resistive Plate Chambers for brain PET imaging and particle tracking and timing (TOF-tracker)
Paulo Fonte, LuÃs Lopes, Filomena M. C. Clemêncio +9
In this work we explore readout architectures for the simultaneous high-resolution timing and bidimensional tracking of charged particles with Resistive Plate Chambers (TOF-tracker…
Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…
Advances Towards a Large-Area, Ultra-Low-Gas-Consumption RPC Detector
João Saraiva, Carlos Alemparte, Daniel Belver +5
Large Resistive Plate Chamber systems have their roots in High Energy Physics experiments at the European Organization for Nuclear Research: ATLAS, CMS and ALICE, where hundreds of…
An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462
Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…
