Welcome to the CERN Accelerator School

The CERN Accelerator School holds training courses on accelerator physics and associated technologies for physicists, engineers, technicians and students. The courses take place in different member states of CERN and consist of a programme of lectures and tutorials spread over a period of one to two weeks.

We welcome participants from all countries world-wide!

COVID info 17/09/2020

Over the past months we have tried to organize the last scheduled CAS course in 2020 under the conditions imposed by the COVID pandemic.
We believe that the two reasons below do not allow us to organize such an event:
1) International travel at the present moment is not predictable. Depending on the evolution in different countries, travel restrictions or quarantine rules can be applied from one day to another.
2) In the unlikely case of a single positive COVID case detected during a course, the whole course, i.e. all students and teachers would have to be quarantined for 2 weeks including a rescheduling of all return flights.

All face-to-face CAS courses are cancelled at the present moment and the activity will resume when the pandemic will be under control.

The CAS team is working on some video teaching concepts. Information will be given in due time.

What our students say about us

CAS provides opportunities: I gained new knowledge and friends, met with important people from the field, arranged for an interesting sabbatical, improved my future possibilities.

— Jiri Kral, CERN
Student of Advanced Accelerator Physics, UK 2017

I liked how many people from different research centers with different nationalities gathers in one place with one interested goal.
Also I like how the courses were well prepared to cover all the interested topics that I need.

— Mohammad AL-Najdawi, SESAME
Student of JAS on RF Technologies, Japan 2017

This school has served with all kinds of aspects which an accelerator learner would seek. Interaction with speakers and school members was of great help to clear my concepts. Case study has been of great use which let us think about broader aspect of accelerators.

— Krutika Natu, SAMEER
Student of Future Colliders course, Zürich 2018

For a beginner like me, it was a very informative and helpful school, I could interact with people from different parts of the world and realize the opportunities ahead of me.

— Aqsa Shaikh, SAMEER
Student of JAS on RF Technologies, Japan 2017

The CAS contributed to my life and career. I learned so many things from lectures and I found time that I conserved with many advanced people for asking my questions. It was pleasure to meet valuable people who are coming from all over the world. I am looking forward to attend next school in the future which is my issue.

— Ayse Nilay Bozdag, University of Ankara
Student of Future Colliders course, Zürich 2018

Thanks for everyone sharing the two happy weeks. Thanks professional teachers to share the valuable and meaningful knowledge with passion.

— Yongchun Feng, Institute of Modern Physics, Chinese Academy of Sciences
Student of Beam Instrumentation course, Tuusula 2018

The topics covered in the CERN Accelerator School were deeply interesting and varied covering many topics that have complemented my day to day work and greatly enriched my current research.

— Stuart Warren, ISOLDE
Student of Advanced Accelerator Physics, UK 2017

I enjoyed the fact that the lectures were not only about vacuum but also about many interfacing fields such as radiation, cryogenics, and so on. Moreover, the experimental sessions made this school truly unique!!

— Marco Morrone, CERN
Student of Vacuum for Particle Accelerators, Sweden 2017

The Cern Accelerator School was so useful for me that I could meet many experts in accelerator from almost every walk of life and I had the chance to improve my knowledge in accelerator physics. I could also find friends in my field. I hope to be one of the best lecturers in future. I would like to thank the CAS project manager for the best management."

— Mina Abbaslou, Khajeh Nasir Toosi University of Technology in Tehran
Student of Future Colliders course, Zürich 2018

It's been a wonderful 10 days of studying together with colleagues around the world.

— Rian Suryo Darmawan, Center for Science and Accelerator Technology, National Nuclear Energy Agency of Indonesia
Student of JAS on RF Technologies, Japan 2017

CAS made this opportunity for coexistence of international people in a peaceful and scientific environment, which resulted in realizing the beauty of the world and having a new hope for the future for me. Moreover, I could benefit greatly by learning from amazing lecturers in my field, and making many friendships from all over the world.

— Jila shams Latifi, University of Tehran
Student of Introduction to Accelerator Physics, Constanta 2018

I enjoyed the multinational environment of great people and a great deal of knowledge that I got out of the lectures.
