After the assemble and calibration process at the LIP detector laboratories in Coimbra, the CorePix muon telescope was transferred to the Lousal Mine.<\/p>\n\n\n\n

The CorePix was installed inside the Waldemar Gallery in the Lousal Mine in April 2022. Since then, it has been operating inside a gallery storeroom, collecting mugraphic data.<\/p>\n\n\n\n

The CorePix was transferred from the Coimbra laboratory to Mina do Lousal in April 2022. In order to be moved along the Waldemar gallery to the storeroom 4, the place where it would remain, it was necessary to dismantle some parts of its structure. Once in it\u2019s place, it has been operating since then, almost continuously, recording the passage of the muons and generating the muographic data that are used in the analyses.<\/p>\n<\/div>\n<\/div>\n\n\n\n

The complete structure of the CorePix has a height of about 1.60 m and it has 4 muon detectors, each of which is a square with a side of 1 m. The detectors work using an ionizing gas that arrives with a low flow through tubes brought from outside the mine, connected to a gas container placed in the guardhouse next to the entrance of the mine, without leaking into the environment.<\/p>\n\n\n\n

When a muon passes through the gas, electrons are released that generate an electrical signal indicating the passage of the muon at that instant. The record of the muons that reached the detectors and that crossed the terrain above them, coming from all directions, forms a map of the surveyed area that is called a muograph (something similar to an X-ray). These muographs are then analyzed to extract information from the interior of the terrain in study.<\/p>\n\n\n\n

The storeroom where the telescope is located was an old storage room for explosive material, used in the exploration of the mine. Nowadays, the gallery\u2019s four storerooms house some museum objects included in visits to the mine, as well as some equipment from external projects, such as the LouMu muography project.<\/p>\n\n\n\n
