CCTVal’s high performance of applied sciences in diverse research areas is proven by the development and production of these kind of experiments. Particle Physics is the focus of the CCTVal Laboratory, which seeks to determine the elemental constituents of matter and the intervening forces in their interactions.  As part of the international collaboration between the Jefferson Laboratory (JLab) of USA and the Scientific and Technological Center of Valparaiso (CCTVal), various experimental projects have been developed in the Laboratory of Experimental High Energy Physics of the USM, specifically in the areas of particle physics, data analysis, manufacturing of parts and development of software for complex JLab detectors.

Faced with this, and amidst the wide spectrum of projects in which CCTVal currently collaborates with JLab, this article will feature two projects for one of the four experimental rooms at the North American Center, specifically for the detector known as CLAS12. First, there is the construction of a new experimental target known as Double-Target System of Precision Measurements of Nuclear Effects (EG2 CLAS12), which will study hadronization processes in heavy nucleus. This contemplates the design, construction and testing of a new experimental target, where electrons collide and hadrons are born.

At JLab, electrons are accelerated which then collide with a fixed target; consequently, the USM Experimental Physics team will utilize various kinds of nuclei to obtain information about their internal nuclear structure, allowing them to study the nature of the strong interaction in the nuclear environment. It is important to highlight that one of the CLAS12 detector´s windows- which is similar in size to the campus’ A-building- can detect almost all the particles when these ones interact and then disperse in all directions. Nonetheless, there are some blind zones where particles are not captured and that information is lost, one of those zones found in the rear area.

To find a solution to that problem, a new complementary detector is being built for the CLAS12, named Back Angle Neutron Detector (BAND) that will detect slow neutrons, helping this way to fine-tune short range nuclear correlation studies. The work on this complementary detector will be carried out jointly by researchers from the Massachusetts Institute of Technology (MIT), Tel Aviv University (TAU) and Old Dominion University (ODU).

Thus, there are three kinds of activities that the CCTVal team performs for the Jefferson laboratory. First of all, observation and collection of physics data, -new physics is looked for-, then these data is analyzed through experimenting and manufacturing of components relevant to those experiments, to finally end with a publication. This collaboration counts with the participation of researchers, under/post graduate students, PhD students and post-docs.

Nuclear High Energy Physics

CCTVal’s high performance of applied sciences in diverse areas of research is proven by the development and production of these kind of experiments. It is important to mention that due to this work, it has been relevant to enhance the study of Modern Nuclear Physics or High Energy Physics. Consequently, development of detectors-like the experimental target- and study of Nuclei, are underway, which currently have various applications, as is in the case of Condensed Matter Physics and Astrophysics. The latter is possible thanks to the observation and interpretation of models that lay out the way in which proton and neutron structures are formed.

In addition, the development of detectors, -both of hardware and software- in projects or experiments of high energy particle physics can also be applied in areas of nuclear medicine or in Big Data processing, as is in the study of weather conditions by satellites.

Due to all of the above, the studies carried out by CCTVal´s High Energy Physics team allows them to also work in the following areas: modeling of stars, condensed matter physics -used to create new materials-, etc., making the area of Experimental Physics stand out as one of the pioneering laboratories, at a national level, in the understanding of fundamental forces and Universal Particles study through the experimentation.

The professors and researchers involved in these projects are: Dr. William Brooks, scholar and CCTVal board member; Dr. Sergey Kuleshov, fellow researcher; Dr. Hayk Hakobyan, scholar and fellow researcher; Iñaki Vega, mechanical engineer of the technology transfer area and the post-docs Ahmed Al-Alaoui and Taisya Mineeva; as well as USM under and post-graduate students.
