ALICE’s Adventures in Switzerland

Hidden 175 metres below the Franco-Swiss border lies a feat of human ingenuity: the Large Hadron Collider (LHC). The LHC is the largest scientific instrument ever constructed, providing mankind with the ability to begin unravelling the very fabric of the universe and everything around us. Now, following long established links with the European Organisation for Nuclear Research (CERN), University of Malta has signed a memorandum of understanding for its scientists’ collaborate with the latest set of experiments at the LHC.  Words by Scott Wilcockson.

Within the LHC particles smaller than an atom are accelerated until they approach the speed of light. Then they are smashed together in collisions 100,000 times hotter than the sun. In CERN’s current A Large Ion Collider Experiment (ALICE) experiments, scientists will recreate and study the quark-gluon plasma that existed milliseconds after the start of the Big Bang. This work will shed light on the strong force thats holds the basic particles of all atoms together and how this generates the majority of the mass of ordinary matter.

Experiments like this produce extraordinary amounts of data, around 100 terabytes per day which is enough to fill 20,000 DVDs. ALICE is now being upgraded through the O2 project which will enable the collection and processing of up to 1 terabyte of data per second for future experiments. This is where Malta comes in.

Dr Kevin Vella started the link between CERN and the University of Malta in 1999 with his work on ATLAS. This experiment helped discover the famous Higgs Boson (responsible for the mass of matter) in 2013. Now scientists and engineers at the University of Malta will help with the upgrading of the ALICE experiment to find ever more elusive particles.

The signing will benefit both the researchers involved and students. University Rector, Prof. Juanito Camilleri, said ‘[the agreement] enables students to be part of a world class organisation […] because CERN kindly recognises the quality of our university and its research.’ The ALICE Collaboration requires a colossal amount of manpower, including 1500 scientists from 37 countries, providing the perfect environment for nurturing collaborative science.

Spokesperson for the ALICE Collaboration, Dr Paolo Giubellino, said that ‘through collaboration […] we can make science and engineering available to everyone. We create new technology, we obtain the scientific results, but the most valuable point is that we train the next generation of scientists’.

The team will also be involved in the development of new software and equipment for the High Momentum Particle Identification detector and the LHC Interface Project. The ultimate aim of these projects is to greatly improve ALICE’s analytical power when observing particle collisions and enable real time analysis by scientists all over the world. Dissecting the universe will never have been so easy.

Minister for Education and Employment, Hon. Evarist Bartolo, said ‘we’ve never let our size limit us, or our limited resources, we have many enterprising people superseding what we’ve built in our past.’ Malta stands on the front-line, alongside a global family of scientists and engineers, in humanity’s exploration of the universe.

Team members from the University of Malta include Dr Vella, Dr Gianluca Valentino and Dr Keith Bugeja (Department of Computer Science), Dr Johann Briffa (Department of Communications and Computer Engineering), and Prof. Edward Gatt (Department of Micro- and Nanoelectronics).

Fostering Creativity and Community: The ART Connect Project at the University of Malta Library

The Library is, in many ways, the beating heart of the University of Malta (UM). The pulse of intellectual life can be felt most profoundly amongst the quiet shelves lined with books and the many students and academics lining the Library’s work desks with their noses deep in their projects. In this sense, the Library is also symbolic of the University’s overall health and vitality, so it is important to balance serious work with serious play.

The evolution of the ART Connect Project has been a journey of dedication and transformation. Inspired by the vision of new librarians and a desire to revamp the Library’s decor, what was once a seed of an idea has now matured into a vibrant platform for artistic expression, collaboration, and community building.

The ART Connect Project aims to connect people through creativity, foster collaboration, and transform spaces, inviting artists and art enthusiasts to celebrate the power of art.

Meeting Challenges Halfway at the Malta Book Festival 2023

Malta boasts 58 registered publishing entities, hosting hundreds of authors writing books across a wide swathe of genres and formats. These numbers emerge from an NSO survey into the book industry, conducted on the basis of the year 2021. Effectively, we could say that there are ‘more authors than churches’ in Malta, with over 700 authors populating the National Book Council’s database.

This hints at a varied industry, the stakeholders of which all fall under the remit of the National Book Council, which seeks to assist, support, and represent Maltese authors and publishers, as well as related industry stakeholders such as translators and illustrators. While the Maltese context does have its own particularities, neither is it immune to the industry’s wider, global realities, a case in point being the price hike on paper caused by the war in Ukraine, which continues to be felt across the board. Maltese publishers must also bear the brunt of this unfortunate phenomenon.

The National Book Council continues to advocate for increased governmental support to aid publishers, whether in this particular challenge or others, and it also offers direct financial aid through the Malta Book Fund, which last year issued a grand total of €120,000 to various industry stakeholders, targeting projects of high cultural value which may not have a straightforward route to market success.

But while some challenges may be met halfway through financial incentives, others require a systemic — or cultural — shift in attitude from all parties involved, which takes a certain degree of workshopping to be borne out. The slow uptake of ebooks bears pondering (the NSO survey saw 146 new ebooks issued in Malta in 2021, contrasted with printed counterparts of 418 in the same year), as does the worryingly high number of authors published without adequate contracts in place.

Maximising Solar Panel Efficiency: The DustPV Project

The DustPV project, led by Prof. Ing. Joseph Micallef, aims to determine the optimal timing for cleaning solar panels using innovative sensor technology and weather data analysis. By addressing the challenges of dust accumulation on photovoltaic panels, the project seeks to enhance solar panel performance and contribute to Malta’s renewable energy goals.
