ATLAS mini model - education/outreach project

created by SaMe on 2013.06.03

Main Section
The ATLAS experiment, at the Large Hadron Collider at CERN in Geneva, is one of the biggest experiments ever build by mankind. The ATLAS detector is searching for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS, and the about 3000 physicists working on it, will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate.

This model illustrates the main features of the ATLAS detector and hopefully helps drawing attention to the field of high energy physics in general and ATLAS in particular.

It's build out of 560 pieces and can be put together in less than an hour.

The idea is to ship a leaflet, with information about the real ATLAS experiment and the physics it is exploring, along with the parts. Thereby we could give each and every customer some insight into this very interesting and fascinating subject and offer possibilities for further education and/or contact to people within ATLAS.

The model is and will be used even more in education and outreach projects to promote particle physics in the public. It serves as a perfect eye catcher, a tool to discuss the basic design of particle detectors such as ATLAS and is the perfect souvenir for people of all age that took part in one of our plenty outreach events.

There is also a very successful larger version of this model (which is not part of this Cuusoo) to be seen in various institutes and exhibitions around the world (see attached below).

Find out more about the real ATLAS experiment and the two models at and, respectively.

Please also have a look at our new related outreach project:
Build Your Own Particle Detector.

Thanks for your support!

[milestone 200]

As promised for reaching the 200 votes milestone, I'm going to write a few words about outreach events/projects in which we have used LEGO and the model(s).

The models have been used at several institutes in events were high-school students got invited to get an introduction to particle physics, do some simple data analysis and build a detector to get a idea of the design and the principle components. Both the small and the large model have been used. We would like to be able to give out the small model as an educative souvenir for such events in the future.

In addition I have just started a "Build your own particle detector" series, were children get to build their own detector (maybe inspired by the ATLAS model, maybe not) and both them and their parent get involved into discussions about particle physics in the mean time.


[milestone 500]

As mentioned above, the model is just one piece in a lot things we are and plan to do with the "building blocks of the Universe" (LEGO). I just announced the winners of our recent "Build your own particle detector" competition, which was held at CERN during the inauguration of the Passeport Big Bang ( We had several hundred children passing through our tent building stuff and both them and their parents learning something about our experiment. You can find some pictures and the winners here: This event would have been just one great opportunity to give out a small model of the ATLAS detector as a prize/souvenir for the winners.


[milestone 5000]

This is simply amazing! The number of supporters almost ten-folded within the last day.
Thank you everyone out there!

As there were a lot of questions/comments about the two designs, I'd like to add a few words.

The vote that is currently ongoing is indeed for the/a small version of the model.
One that could be bought, built and kept at home by many people of all age.
Also it is more a vote for the idea, as LEGO might/will do some adaptions/modifications to the design once it has been selected for production.

The large one, which is about a meter in length and would probably cost several hundred dollars, is thought of (at least for now) as an exhibit for ATLAS institutes. I somewhat doubt that it would make it through the reviewing process, as the number of people that could actually afford it is simply too low.

That said, once we made it through the review and to an official product, I can try and invest some time to provide a complete list of pieces or even a final computer model (which does not exists yet, as it went though some iterations once I had the pieces) of the large one.

Thanks once again to everyone who voted and/or facebooked/tweeted/shared the link!!!
And of course to IFLS (not sure I can write this here, but you know who I mean).


[milestone 10000]

Thank you very very much to everyone who supported the idea!
The is awesome, I am very much looking forward to hear from LEGO :)

LEGO Review Results for ATLAS Mini Model


First and foremost, congratulations to SaMe for reaching 10,000 supporters on LEGO CUUSOO, and toward everyone for all of the support of the ATLAS Mini Model project! The results of the LEGO Review are in and you can see full details on the LEGO CUUSOO Blog.

Review Results for ATLAS Mini Model
Our team has thoroughly considered the possibility of releasing this project as a LEGO set according to the criteria of the LEGO Review. Unfortunately the LEGO Review Board has decided that we will not produce this project as a set.

Thank you to SaMe for the passion and creativity that went into this project, and to all of you who voted so that we would have the opportunity to consider this as a potential LEGO set. We’re sorry to deliver this disappointing news.

How do we arrive at our decisions?
By gaining 10,000 supporters, a fan-submitted project moves from the Idea Stage to the Review Stage, where it earns the opportunity to be considered as a future LEGO® set in a process called the “LEGO Review.” Gaining 10,000 Supporters is just the first step in this process.

A "LEGO Review Board" composed of professional set designers, product managers, marketing representatives, and other key team members examine each qualified project. They build concept models and determine if the concept meets our high standards for what it takes to be a LEGO product; including factors such as playability, safety, and fit with the LEGO brand. Every potential LEGO product, including those developed internally, goes through a similar process and must meet the same standards.

The amount of time this takes varies due to all the factors involved. Unfortunately, this process sometimes means that well-conceived projects that gain just-as-passionate followings have to be turned down. Please note that the LEGO Review Board makes all final decisions on which new sets the LEGO Group will release based on CUUSOO projects.


Congrats on 10,000 Supporters, SaMe!


Oh my Higgs Boson!

Congratulations to SaMe and to our new friends who really, really love science, on successfully reaching 10,000 supporters in such a short time.

You’ve done a great job compressing your ATLAS model down to a size that is accessible by students, families, and science departments around the world, to spread understanding of the field of particle physics. You’ve also connected with a passionate audience of people who want to encourage greater interest in science education. We now officially advance this project to the Review phase.

What happens now?
This project moves from the Idea stage to the Review stage. A "LEGO Review Board" composed of designers, product managers, and other key team members will examine the idea. We'll build concept models and determine if the concept meets our high standards for what it takes to be a LEGO product. This includes factors such as playability, safety, and fit with the LEGO brand. Every potential LEGO product goes through a process like this and must meet the same standards.

The LEGO Review Begins in September
This project qualifies for the quarterly review beginning in September. For more information about the quarterly review process, see this blog post.

The review is a thorough process and from its start, and can take several months. When finished, we make a "go/no go" decision to develop and sell a product based on the “ATLAS Mini Model - Education/Outreach Project” concept.

When the review is complete, we will inform you of our decision. If green-lit, this project goes into the longest phase of the project; the Development phase. During this time, LEGO model designers refine the product and develop it for release, we create the product materials (box, instructions, marketing), and get everything ready for a production run. This also takes several months.

We will post follow-up information and our decision here.



Note: If your idea is selected, the LEGO Group will make the final decision on how your proposed product should be produced, the final design, applicable licenses, production run size, sales channels, etc. Please understand that our comments here do not have an effect on the LEGO Review that will take place if the project reaches 10,000 supporters.
