A double-target system is planned to build and to install in the experimental Hall B and D in the Jefferson lab for precision measurements of nuclear medium effects in electron scattering with 10–11 GeV electron beams. This system will allow a precise comparison of elementary targets such as deuterium and hydrogen to heavy solid targets (carbon, iron, aluminum, tin, lead, uranium, etc.) to study subtle medium effects such as hadronization in nuclear medium, color transparency, and nuclear short range correlations. During the data acquisition one cryo-target and one solid target will be exposed to the beam simultaneously.

Due to its high penetration capacity, when placing sensible detectors above and below an object of interest, it is possible to monitor a muon, as it will go through each of the detectors. Considering this, if a line is traced across a minimum of two points, the path of incoming and outgoing muons could be identified. It is known that the crossing of muons through heavy materials, cause deviations in their path, thus, if a deviation can be observed at a certain point, this would mean that the existence of a dense material is probable. On the other hand, if there is no deviation, we can then conclude that the muon would have gone through air, and this would therefore be an underground fissure.

On the outset, this project consists on the design and construction of a calorimeter called Pre-shower, sensitive to the position where a particle passes through and to the energy deposited by this one in any of the scintillator crystals of its square arrangement.

ATLAS is an experiment of major importance located in the Large Hadron Collider (LHC), a tunnel in the shape of a ring, 27 kilometers in diameter where particles travel at a great speed, colliding against each other.

The construction of the Aguas Negras tunnel that will link Chile and Argentina is a great opportunity to have, for the very first time, an underground scientific laboratory of great depth in South America, where state of the art science will be carried out. Agua Negra Deep Experiment Site, A.N.D.E.S signifies a scientific integration among Latin American nations. The idea is to stablish an underground laboratory that will attract scientists from all over the world to develop first line experiments and to stablish experimental collaborations in South America.

This project represents a great opportunity to the scientific community because of the site´s geographical features which are very favorable from a scientific point of view. There is only 15 laboratories of this kind in the world, of which ANDES would be the third deepest in the planet at 1,750 meters underground, and the first one in the Southern hemisphere.

After successfully working in experimental projects related to the area of Particle Physics, data analysis, parts manufacturing and software development, CCTVal and Jefferson Lab (JLab) were awarded a grant fund from the National Aeronautics and Space Administration, better known as NASA, with the objective of implementing a Fusion System of scientific information for satellite measurements on Earth for which a software of high scalability must be developed, capable of processing massive amounts of satellite data.

This project will be carried out by two IT civil engineers from Santa Maria University, Sebastian Mancilla and Ricardo Oyarzún, together with two CCTVal members, William Brooks and Hayk Hakobyan.

The team will work with nine years of data relating to climate and weather from all over the world stored by NASA which must be analyzed in the most assertive way possible.

In addition to CCTVAl´s team, the project counts with the participation of researchers from JLab and NASA.

The Mirror Project seeks to master the fabrication techniques for making lightweight mirrors with a backing material of carbon-fiber–reinforced polymer (CRFP) used in large scale particle detectors such as the Ring-Imaging Cherenkov (RICH) detector. The objetive is to develop manufacturing capacity for the production of lightweight mirrors, used in Particle Physics and astrophysics research. These mirrors are a component of particle detectors capable of detecting subatomic particles with positive or negative charge passing through a transparent medium, and which can be used in High Energy Physics research, nuclear physics experiments, and Astrophysics studies.

In the first stage of the project, a prototype will be manufactured with the appropriate smoothness, dimensional accuracy, and reflectivity features. In order to fabricate the mirrors it is necessary to   construct a layup form or “mandrel” to shape each of the mirror parts, a physical vapor deposition (PVD) chamber to deposit a reflective layer and a protective layer of materials such as aluminum and silicon oxide, and a polishing station needed to achieve an optical-quality surface on the mandrel.
