Are there any costs involved in taking part in the competition?

There are no fees or anything similar, taking part is completely free. For the winning teams, BL4S will cover the full costs of the winners' participation to the competition, including travel, accommodation and three meals per day.

Who is eligible?

High-school students from all over the world aged 16 and older on the first day of their visit at the laboratory (usually September of the year of the competition) are eligible. Younger students may form part of entering teams, but they cannot be invited in case of winning te competition.

Is it possible for students under the age of 16 to participate in the competition?

Yes, but... For the participation to the competition there is no age limit. Students under the age of 16 can be members of a team and will receive certificates. The only limitation is that in case the team wins, only students that are at least 16 years old in September can be invited.

What is being offered?

2017 & 2018 edition
A chance to win a trip to CERN and conduct a student-led particle physics experiment at the world’s largest particle physics laboratory. Before coming to CERN the winning teams will have the opportunity to work together with CERN scientists on their ideas on how to use the beam line and plan out a particle physics experiment. For short-listed teams there will be additional prizes such as CosmicPi particle detectors and t-shirts. All participants will receive a certificate.

2019 edition
A chance to win a trip to DESY and conduct a student-led particle physics experiment at a world-leading accelerator centre. Before coming to DESY the winning teams will have the opportunity to work together with DESY and/or CERN scientists on their ideas on how to use the beam line and plan out a particle physics experiment. For short-listed teams there will be additional prizes. All participants will receive a certificate.

Where will it happen?

In 2014 - 2018 at CERN’s fixed-target beam facilities, near Geneva, Switzerland.
In 2019 at DESY in Hamburg, Germany.

When will it happen?

The registration opens the year before the competition in summer. Proposals can be submitted until the deadline at midnight CET on 31 March. The winning teams are notified in June. The winning teams will be invited to the executing research laboratory in September and/or October.

Why is CERN doing this?

This is an ideal opportunity to expose today’s cutting-edge physics to tomorrow’s scientists. The Beamline for Schools competition began in 2014 to celebrate CERN’s 60th Anniversary and had already some successful runs.

How do we enter?

Go to the competition webpage and follow the instructions you’ll find there. Remember, you must submit your written proposal and video by midnight CET on 31 March.

Who can make a team?

Students can be from a single school, from multiple classes, from different schools or even countries. Each team has to have at least 5 members and has to be represented by an adult coach.

How many people per team?

The minimum is 5. There is no upper limit but for the winners a maximum of nine students will be invited, with one or two adults acting as coaches. Data transmission and web link-ups will allow additional students to participate and analyse data remotely.

How do we submit videos?

Publish your video on Vimeo or YouTube and submit your full proposal via the submission form including the link to your video.

In what languages can we submit our proposals?

All submissions must be made in English. Please note that we cannot consider submissions made in other languages. 

What kind of experiments can we do?

It is up to you and your team how you want to use the beam line facility. The beam line will be fully equipped; with a pre-determined set of detectors that you can choose from to design your own experiment. Have a look at the beam and detector document to learn more about the beam line facilities and its possibilities. In addition to the equipment provided, you may also bring your own detectors (maybe you can even build one yourself as previous winners have done).

How are the proposals judged?

We will evaluate the proposals on these criteria:

  • The feasibility of the experiment
  • The ability to follow the scientific method
  • The motivation of the experiment and why you want to come to DESY
  • The creativity of the experiment and the 1-minute video

We are not expecting fully developed experimental proposals. Your motivation and creativity are very important to us.

We don’t know about particle physics. Is this a problem?

All students enthusiastic about learning are encouraged to participate. We recognize that most students have little to no experience with particle physics when they begin the competition, but will learn as they progress through the competition. Volunteers are available for providing help to the team. In addition CERN’s website has several resources for introducing particle physics.

Who will evaluate our experiment proposal?

A group of physicists and engineers will pre-select the proposals. From 2014-2018 the short-listed experiments were sent to the SPSC, the committee that validates all proposals for experiments at the laboratory’s Super Proton Synchrotron (SPS) and Proton Synchrotron (PS) accelerators, which selected the winners. In 2019 a joined committee of DESY and CERN scientists will select the winners.

 

Technical FAQ's for the conditions at DESY

What is DESY and what is DESY II?

DESY, like CERN, is an acronym. It stands for "Deutsches Elektronen Synchrotron” (German electron synchrotron). Originally it was the name of an accelerator. Today the acronym refers to a large research institute that operates many different accelerators. For more information please visit this website. The Acronym “DESY II” refers to the second generation electron / positron accelerator of DESY.

Can we find a Higgs boson?

No. Higgs bosons can only be observed in the Large Hadron Collider (LHC) at CERN, the largest accelerator in the world. Students will be using a beam of particles from “DESY II”, a smaller accelerator.

Can atoms or molecules be accelerated with DESY II?

No. DESY II can accelerate only electrons. When they hit a target, they produce, via one intermediate step, a secondary beam composed of electrons and positrons (the anti-matter twins of electrons). The momentum of the beam entering the experimental area can be set by the user and it can range between 1 and 6 GeV/c. Additional details can be found here, together with information about detectors and other experimental facilities.

Is it feasible to recombine molecules (i.e. helium) with DESY II?

No. Our professional physicists just managed to produce hydrogen from protons and electrons. Recombining helium is more difficult. In addition the beam does not contain alpha particles. Its exact composition can be found here.

Can we get an antimatter beam?

Yes. The DESY II beam contains anti-electrons as described here.

What are the professional physicists at DESY doing with the beam?

Most of the time we use the beam to test prototypes of new detectors before they are installed in the large experiments. While some of these detectors are quite complicated we sometimes also use very simple detectors that can even be built at a school. Examples are scintillators or silicon detectors based on commercial image sensors. Other scientists use the beam in order to test the radiation tolerance of their electronics.

Can we bring our own equipment/detectors to the beam?

In principle, this is possible, but we have to evaluate it individually. So please contact us during your early planning phase.

Can we control the collimators?

Yes, the collimators can be controlled. Please note that if you close the collimators in order to select a more narrow spectrum of particle momenta, you reduce at the same time the number of particles that enter into the experimental zone.

The beam at DESY only provides electrons. What can we do with them?

We have collected many ideas for experiments. You can find them here. It is perfectly OK if you take one of them as the basis of your proposal. They can be refined in many ways. You can, of course, also use your own creativity to think about an experiment. The contact persons are happy to help you in case of questions.

Is it possible to use a virus sample or bacteria in the experiment? What about other biological material?

Unfortunately is not possible to irradiate any kind of samples that contain living organisms including seeds, roots or cells. Inactive organic material such as wood or leather can be exposed to the beam.

What is the speed of the particles in the beam?

As electrons are very light, DESY II can accelerate them to almost the speed of light. You don’t believe that? Design an experiment to measure their speed and convince yourself!

Can I see the beam when it is on?

No. The beam is invisible to the human eye. Our detectors, however, are sensitive enough to detect even single electrons. You can therefore observe the beam through “electronic eyes”.

I still have some technical questions. Who can I ask for help?

Please feel free to send us your questions to bl4s.team@cern.ch. For obtaining quickly the most useful answer, you should include some short information about your ideas/your proposal and how our answers would influence your experiment.
