The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter. Although it has the same scientific goals as the ATLAS experiment, it uses different technical solutions and a different magnet-system design.

The CMS detector is built around a huge solenoid magnet. This takes the form of a cylindrical coil of superconducting cable that generates a field of 4 tesla, about 100,000 times the magnetic field of the Earth. The field is confined by a steel "yoke" that forms the bulk of the detector's 14,000-tonne weight.

An unusual feature of the CMS detector is that instead of being built in-situ like the other giant detectors of the LHC experiments, it was constructed in 15 sections at ground level before being lowered into an underground cavern near Cessy in France and reassembled. The complete detector is 21 metres long, 15 metres wide and 15 metres high.

The CMS experiment is one of the largest international scientific collaborations in history, involving 5000 particle physicists, engineers, technicians, students and support staff from 200 institutes in 50 countries (September 2019).

Every day, we have classes for six or seven hours, which means we usually study six or seven different subjects. The day begins at 8:05 in the morning, when students enter their bright and welcoming classrooms. Each lesson lasts 45 minutes, filled with learning, discussions, and activities that keep us engaged.

We have six breaks throughout the day, each lasting between 5 and 10 minutes. These short pauses give us the perfect chance to relax, chat with friends, or get a quick snack before the next lesson begins.

Classes finish in the afternoon, either at 1:10 or 1:50, depending on the schedule. Throughout the day, we move from subject to subject, making every hour interesting and full of new things to discover.

Το Εθνικό Πάρκο Δέλτα Αξιού ( Εθνικό Πάρκο Αξιού - Λουδία - Αλιάκμονα) περιλαμβάνει τη Λιμνοθάλασσα Καλοχωρίου Θεσσαλονίκης, τις εκβολές του Γαλλικού ποταμού, το δέλτα του ποταμού Αξιού, καθώς και την κοίτη του έως τα σύνορα της Ελλάδας, το δέλτα του ποταμού Αλιάκμονα, τον υγρότοπο της Νέας Αγαθούπολης και τους υγροτόπους της Αλυκής Κίτρους. Η προστασία που παρέχεται ως σήμερα στην περιοχή οφείλεται στην ένταξη του το 1971 στην Σύμβαση Ραμσάρ ως Υγροτόπου Διεθνούς Σημασίας και στη ένταξή της στο δίκτυο περιοχών Natura 2000. Επίσης έχει περιληφθεί στον κατάλογο των σημαντικών περιοχών για τα πουλιά IBA ( Important Bird Areas- Σημαντική περιοχή για πουλιά).

Το κλίμα της περιοχής είναι το καλοκαίρι θερμό, χωρίς ιδιαίτερες θερμοκρασιακές εξάρσεις, και το χειμώνα ψυχρό και υγρό. Σπάνια παρατηρούνται ακραία φαινόμενα το χειμώνα, με χιονόπτωση, ενώ ακόμα σπανιότερα παγώνουν τα νερά. Το μέσο ετήσιο ύψος βροχής φθάνει τα 442,5 χιλιοστά, με τις περισσότερες βροχές να πέφτουν το φθινόπωρο.

Η χλωρίδα του πάρκου δεν περιλαμβάνει ενδημικά, σπάνια ή απειλούμενα είδη, παρά μόνο τα συνήθη είδη των υγροτόπων, των υφάλμυρων εδαφών και των παραλίων.

Τα οικοσυστήματα των ποταμών του Πάρκου είναι ιδιαίτερα πλούσια σε αριθμό ειδών. Μόνο στο ποταμό Αξιό έχουν μετρηθεί συνολικά είκοσι έξι είδη ψαριών, ενώ στον Αλιάκμονα υπάρχουν είκοσι έξι είδη αυτόχθονα και τέσσερα εισαχθέντα είδη. Ιδιαίτερα πρέπει να αναφερθεί το μαυροτσιρώνι (Rutilus Macedonicus). Μεταξύ δε των θηλαστικών περιλαμβάνονται o Μυοκάστορας (Myocastor coypus), ο Λαγόγυρος (Citelus Citelus, η Βίδρα (lutra lutra) και ο ελληνικός Βούβαλος (Νεροβούβαλος).

Let us take you on a little tour of our school! As we enter the building, we step onto the ground floor. Here, you’ll find the teachers’ room, the canteen, the toilets, a classroom, the Chemistry and Science lab, and the director’s office. Everything is organized and ready for learning!

Now, let’s go upstairs to the first floor. There are six classrooms, each one bright and welcoming. Inside, you’ll see desks and chairs for the students, the teacher’s desk, a whiteboard, and a smartboard, all set up for lessons and activities.

Our school building is colorful and cheerful, making it a happy place to study. Step outside, and you’ll see ten benches where students can sit and chat with friends. There’s also a basketball and a volleyball court for sports and fun.

And that’s not all!Our school has lots of sports equipment—basketballs, footballs, volleyballs, badminton rackets, and even ping pong tables—so there’s always something to keep everyone active and entertained.

Welcome to a year full of exciting activities and unforgettable events at our school! Every year, we embark on educational trips to amazing places like museums, theatres, and cinemas. We celebrate special occasions, join in fun school events, and always find new ways to learn and explore.

Our students take part in scientific conferences, cultural programs, environmental projects, and health education activities. We also compete in sports, literature, and mathematics competitions, challenging ourselves and discovering new talents. Technology plays an important role too—we’ve even created our own digital student magazine!

This year, we are especially excited about participating in student programs and conferences in Cyprus and other cities across our country.

Six times a year, we enjoy a “Sports Day,” when all the students gather in the schoolyard to play games and have fun together. And at the end of the year, our senior classes go on an educational trip to other European countries for three or four days. This year, we’ll be exploring the beautiful city of Vienna, Austria!

In September 2024, our school embarked on an unforgettable journey to some of Europe’s most beautiful countries: Switzerland, Italy, France, and Germany. One of the highlights of our trip was visiting CERN, the famous experimental research center, where we learned about experiments recreating the conditions of the Big Bang—an incredible experience that brought science to life!

Our school also participates in exciting European programs like Erasmus. Over the years, our classmates and teachers have visited schools in Barcelona, Valencia, and Copenhagen, and we have hosted teachers and students from Spain at our own school.

Our senior students have enjoyed educational trips to Rome, the European Parliament in Brussels, and CERN in Switzerland, and we’ve explored amazing cities like Milan, the French Alps, Annecy, Annemasse, Geneva, Stuttgart, Bern, and many more. This year, our next adventure will take us to Vienna, Austria!
