Outdoor systems performance and upgrade

Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort by installing several systems and continues to work on their optimization, while simultaneously studying and developing new approaches that can use RPCs in outdoor applications. In particular, four detectors were deployed in the field at the Pierre Auger Observatory ...

Projeto LouMu - Muografia no Lousal

A viabilidade da muografia como técnica de sondagem tem sido demonstrada em diversos trabalhos ao redor do mundo, desde os seus primeiros passos. A muografia com muógrafos em ambiente subterrâneo tem um lado fácil devido à ausência da radiação de fundo, mas, por outro lado, o fluxo de muões é muito menor em comparação com o que é medido na superfície. É uma questão de condições geológicas e subterrâneas, deteto...

Muography in the university and in the museum

The LouMu team joins together specialists in particle detectors and in cosmic ray analyses, geophysicists and science communicators to muograph an underground gallery of an old mine, now open to visitors of a science museum. The muon telescope is made of Resistive Plate Chambers (RPCs) developed to operate stably and with low consumption at remote locations, and it has been tested in the Coimbra University, bef...

Muography for Underground Geological Surveys: Ongoing Application at the Lousal...

The use of muons for geophysical surveys has been proved successful in numerous projects around the planet. The use of muography in an underground environment has an easy side, when compared to the surface, due to the absence of the background radiation. On the other hand, the muon flux is much lower than what is measured on the surface. Geological and underground conditions should be considered when defining t...

Mercury exposure through fish consumption in Portugal: need of public health in...

In Portugal, fish consumption has a significant role in daily diet. The Portuguese consume an average of 61.5 kg of fish per person/year, being the country with higher consumption in the European Union, and in the world, after Korea (78.5 kg per person/year) and Norway (66.6 kg per person/year). It’s well known that fish is rich in omega 3, which has valuable effects on adults and children since that benefits i...

MARTA: a high-energy cosmic-ray detector concept for high-accuracy muon measure...

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 good space and time resolution. The muon detector is shielded by placing it under another detector able to absorb and measure the electromagnetic component of the showers such as a water-Cherenkov detector, commonly used in air shower ...
