Javier Ruiseco Lopez, a Mechatronics Engineer from Instituto de Estudios Superiores de Tamaulipas and Abraham Villatoro Tello, student from Benemérita Universidad Autónoma de Puebla, have been working in the past two months on the ALICE Cosmic Ray Detector (ACORDE) as the ACORDE team prepares for the second run of the LHC.

Javier Ruiseco Lopez is currently studying for his MSc in Electronics degree at the Benemerita Universidad Autonoma de Puebla. Javier says: “I decided to study electronics because I like the way it can be applied on anything, from simple things to robotics, detectors, computing, etc.” He recently joined ALICE on ACORDE subdetector and is the newest member of the team. He adds: “I enjoy working at CERN. There is so much to learn and it is exciting to know that electronics is a crucial part of a detector. Electronics are in charge of delivering reliable data that help Physics develop new theories and test their actual ones”.

Javier thinks that nowadays more specialists in the area are needed and he feels that “it’s really exciting to form part and represent your country in an international collaboration where there’s people from all around the world. Moreover, working on detectors is very interesting and a very enjoyable experience.”

Abraham Villatoro Tello is also a student from Benemérita Universidad Autónoma de Puebla. He has completed a degree in electronics, and is currently studying for a Masters in Applied Physics. He says: “The main motivation for these studies was that I always liked to know how things around us work and there's no better way of knowing than studying physics."

It is the second time that Abraham visits CERN and he adds: “The first time I came here was to work for the CERN Open Days in 2013”. Arturo Fernandez Tellez had travelled with Abraham and a group of students to CERN to present the Cosmic Piano and show people how particles are detected by modern experiments. Abraham came back in March to work on the ACORDE detector. They recalibrated the sensors and polished some details while at the same time they modified the electronics in order to meet the new specifications of ALICE.

Abraham adds: “As a student in electronics, I'm fascinated by the way all detectors can work together, handling the amount of information generated in order to finally form such a complete experiment. Also the fact of being here, working in collaboration with people from so many places, feels great. I hope more students from México find themselves interested in HEP experiments and continue in this field of research”.
