The AMIGA UC is composed of a 750 m hexagon with one muon counter (MC) linked to a surface detector (SD) in each vertex and in its centre. Deployed in the field there are currently 6 MCs composed of one scintillator modules (SM) with a surface area of 10 m2 each. There is also a MC with four 5 m2 SMs and four 10 m2 SMs, referred as a twin position. There are also three other 5 m2 SM and one 10 m2 SM buried in the field that do not have electronics yet. Each SM has 64 plastic scintillator strips of 4.1 cm wide by 1 cm high. The strips of the 10 m2 SM are 4 m long and half this length for the 5 m2 SM. In summary, there are in total 14 SMs fully operational in the field buried nearby the companion SD at a 2.3 m depth and other 4 SMs deployed without electronics, remaining 17 out of 35 SMs to complete the UC and 2 twins.
