Escaramujo - Pasto

The Escaramujo workshop in Pasto, Colombia, was held in the Autónoma Universidad de Nariño (AUNAR), and in the Universidad de Nariño (UdeNar), between the 30-Nov-15 and 3-Dec-15. It was organized by the professors Jaime Betancourt and Oscar Rodríguez, and we counted with the support of the professors Rafael Llerena and Jaime Ortiz (AUNAR), who also got involved in the assembly and data taking of the detector with their inherent scientific curiosity that we all have inside. We also had the honor of receiving Alberto Quijano, founder and director of the Observatorio Astronómico of UdeNar.

The participating students were:

John Estrada
Ivan Dario Rivera
Sebastian Acosta
Yamid Eraso
Jairo Rodriguez
David Dueñas
Faiber Rosas

The city of Pasto lies at the foot of the impressive Galeras Volcano. The group of participants decided to fabricate a cosmic ray telescope and go to the field to measure the muon attenuation due to the volcano. The field day was successful, where we could measure the cosmic rays flux in situ, and analyze the feasibility of moving towards volcano tomography with muons.

Hands-on. Students and professors working of the device, assembling it.

Starting up the setup. The neighbor of the white house, at the left of the students, kindly allowed us to connect to the electric grid and to use the restroom. For the love of science.
