In April, we successfully completed the installation of the new Clean Room in Hall C of the underground facility. The design and construction were carried out entirely by our team, and the levels of airborne particles meet the ISO 7 standard, ensuring an ultra-clean and controlled environment. This room already houses one of the lowest-background Germanium detectors and is prepared for the installation of two additional detectors in the coming years.

Ali Dastgheibi-Fard, researcher at the Laboratory of Subatomic Physics & Cosmology, presented in his seminar a study on the mechanisms of radon implatation and its impact on detector components. He also discussed methods for measuring, preventing, and cleaning contaminated surfaces, with the goal of reducing background radiation in rare event experiments. This type of research is key to improving the sensitivity of detectors used in astroparticle physics.

At the LSC, we organize informal talks where our staff share the progress of their research, always accompanied by a coffee. On April 1st, our colleague Enrique Roig presented the latest advances from his PhD thesis on cellular aging, focused on the development of an epigenetic clock, a bioinformatics tool capable of predicting age based on methylation patterns. Bioinformatics is beginning to make its way into experiments at the LSC.

On March 26, the LSC held its Science Day for the second year in a row, welcoming students from the 2nd year of Bachillerato from schools in Jaca. Throughout the day, students took part in various workshops and learned about key techniques used at the LSC, such as copper electroforming and gamma spectroscopy. As in the previous edition, the day concluded with a visit to our underground facilities.

Nicholas Prouse, a researcher at Imperial College London , presented in his seminar the Water Cherenkov Test Experiment (WCTE), which began collecting data at the end of 2024 in the CERN T9 beam. The data collected by WCTE will be used to improve pion reconstruction in water Cherenkov detectors and to analyze interaction cross-sections using a known particle flux. The results of this experiment will have a direct impact on Super-K, T2K, and Hyper-K.

On March 19, the LSC participated in The Wave conference, held at the Zaragoza Conference Center, where we conducted a workshop on radon, given the national interest in this topic and our expertise in its air monitoring and the measurement of its emanation in materials. In its second edition, The Wave brought together experts and companies for three days to explore how to transform technology into a real competitive advantage.

From March 12 to 14, the LSC participated in TRANSFIERE, Spain's most important R&D&I fair, held in Málaga. This forum connects the entire Spanish innovation ecosystem and boosts its international projection, promoting the transfer of scientific and technological knowledge. Together with 11 other ICTS, we showcased the services we offer, reaffirming our commitment to maximizing the impact of research on society.

The LSC successfully completes the implosion test campaign, in collaboration with SOCIB, for the validation of protective covers for the photosensors of the international neutrino telescope Hyper-Kamiokande.

Like every year, the LSC joins the celebration of the International Day of Women and Girls in Science, a day dedicated to highlighting the essential contributions of women to the scientific and technological community. We remain committed to promoting education in equality and increasing the visibility of women in science. Happy International Day of Women and Girls in Science to all!

Last week, the eighth implosion test campaign was successfully completed to validate the protective covers of the sensors for the future HK neutrino telescope. Over three weeks, a team of 15 researchers from LSC, DIPC, UdG, and Japanese institutions conducted the tests at the SOCIB facilities in Palma. A total of six tests were carried out, confirming that the cover prototype can contain an implosion in case of failure. One step closer to ensuring the safety of the 22,000 eyes of HK.
