Introduction

The ATLAS plastic brick model was designed and first built by Sascha Mehlhase.

This model is a 1:50 scale version of the real ATLAS experiment, situated at CERN - the European Organisation for Nuclear Research, in Geneva, Switzerland. The ATLAS detector is searching for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, unification of fundamental forces, and evidence for dark matter candidates in the Universe.
If you want to know more about the ATLAS experiment, visit the ATLAS web site and/or follow us on Twitter and YouTube.

The model is made of in total 9517 pieces, is roughly in scale to a plastic man and has a size of about one meter in length and half a meter in diameter. A quarter sector of the Inner Detector and the calorimeters can be taken out to better illustrate the individual layers of the actual detector. A scaffolding and two scales help to further illustrate the size of this experiment and a legend allows to identify the individual parts.

In case you feel like reading one of the many articles, blogs and whatnot published about the model, have a look at this little media coverage overview.

The instruction videos featured on this page have been produced with the kind help and support of Jeppe Madsen and Gertie Skaarup at the Niels Bohr Institute in Copenhagen.

Stats

The initial (though not complete) 3D design of the large model took about 48 hours, while the construction of the first brick model, including a few iterations, took about 33 hours. The small model took a few hours to design and slightly less than an hour to build.
As of now, I have ordered 35 large and 111 small models. The models have been shipped to 39 institutes in ten different countries around the world. Not including overhead, this corresponds to in total 395.255 pieces being shipped to the various places.
I have build three large and three small models myself (including the initial designs).

Remarks

To get started on the construction of the model, here is some general remarks.
PLEASE READ THESE REMARKS BEFORE ORDERING OR BUILDING THE MODEL.

Patience young Skywalker, patience! - you will need it!
It turned out to be a good idea to sort the delivered pieces by colour and optionally between tiles and bricks (three times as high as as tiles) as well. It is tedious at the beginning and will consume a good fraction of the construction time, but it will speed up you brick search significantly in the end.
It turned out, when ordering through ATLAS, you'll get the pieces sort by kind.
Please be sure you have enough time to build the model! It took in total 33 hours for someone who knew where pieces belong, so it might / will take longer for most other people.
During construction, try to place the model on a table accessible from all sides. Or even two tables, that you can access it from below at late stages of the build.
This model was designed in an iterative approach. Therefore some pieces are not chosen entirely by logic or best fit, but by the shear fact that they represent the simplest (in terms of not modifying the whole model again) solution to a bug / problem.
Once you built a version of the model, put one of the labels provided below next to the exhibit and send me an email about the location and duration of the exhibition (see above).
In case you cannot figure out a specific piece/placement, it can pay off to continue with the clip for a few seconds: you might get an idea from one of the following camera angles.
You will have some extra/remaining pieces left after the construction! Please consider to 'recycle' the pieces and reward those spending a lot of time on this effort.
You might have some missing/wrong pieces. Please use the usual LEGO customer support along with your ordering details (on/in the shipping box) to get them replaced.

F.A.Q.

To answer some of your questions in advance ...

Can I order the pieces from/through you?: Maybe and no! If you are a member of the ATLAS collaboration, it's a maybe (contact me).
If you are an outsider, it's definitely a no!
Can you assist me in building the model?: Yes, I'll gladly do so, if you pay the tickets and the hotel :)
Did you earn any money from/with this?: No. Please do not ask why!
What do I do with extra/remaining pieces?: Please consider to 'recycle' the pieces. Thanks!
Where can I see the model?: For the moment you have to come to the second level of building M of the Niels Bohr Institute in Copenhagen.
But have a look in the exhibitions section of this page for more (upcoming) locations.
What can I do when I cannot figure out a specific step/piece?: First of all, try to continue watch the according clip. Often you can get the solution to your problem from a later camera angle. Finally you can drop me an email and I'll try to add more specific hints on this webpage.
Who payed for the model(s)?: The first model was financed from the outreach budget of the High Energy Physics group at the Niels Bohr Institute in Copenhagen. The model used to make the construction manual videos, was payed by the ATLAS Collaboration.
Why do some pieces make no sense to me?: The model was designed in an iterative process, so some pieces have been replaced to fix bugs of an earlier stage and created weird (non-optimal) configurations. Some flaws might even be still in the model described here. Let me know if you find them.

from the second time you use white 1x1 bricks the sector is not symmetric anymore
the side with the white 1x1 bricks is going to support the slanted bricks in the upper quadrant

Structural components

The structural components include everything within the barrel part that does not represent an actual detector component. This covers the two rows of feet as well as the frame(s) that carry the toroid magnets and the muon detectors and keep the inner part centred.

The two rows of supporting feet are identical to each other and each made of 229 pieces.

the first piece needs to be build six times for each wheel
the second piece needs to be build two times per wheel
the third and forth piece (~2:55, ~3:30) both need to be build six times per wheel
the fifth and sixth piece (~4:20) both need to be build two times per wheel
the seventh (~4:30) seven times and the eighth (~4:40, featuring the light grey bricks) one time per wheel

Barrel assembly

The construction of the barrel part is split up in two clips.

make sure the two sectors without 'light grey brick 1x2 cross hole' point the right way and are next to each other
check with the final model how many 'dark grey brick 4x4 round' pieces you need in between two of the seven wheels
you case use the white tiles from the Muon Spectrometer to build a stabilising structure as shown in the clip
never mind some sacking when setting the first two wheels in place (see clip), usually the can be re-adjusted quite easily
for the innermost ring (added a individual pieces with the grey bricks in the bottom), make sure you alternate the pieces around the actual wheel (see later part of the video)
when inserting the inner barrel centre, make sure the centre of the inner part is aligned to the centre of the middle wheel
the grey bricks of the lower innermost ring should sit left or right of the centre (depending on the side of the lower part of the innermost ring) and not centred in the middle (see image , where the grey bricks sit off centre on the right)

the middle light grey pillar at the top, should be centred at the top of the inserted part

the distance between two light grey pillars is six units

depending on skills and finger size :) it can be advantageous to add the barrel muon chambers (white tile in muon assembly video) in the barrel part already while setting the frames together

There is in total 16 toroid magnet coil end-caps, one at each side of all eight toroid coils. They each consist of 42 pieces.

this piece is very 'unstable' (sorry for that)
the black rod has to sit loosely at both ends (needs to be length seven, only six and eight exist)
it's best to finish the assembly of the coils on the model (as shown

Muon Spectrometer - Big wheels

Muon Spectrometer - Assembly

This clip shows the assembly of both the inner and outer wheels of the Muon Spectrometer and the barrel muon chambers.

watch out! only the innermost layer of muon chambers consists of 6x6 tiles, the other three are 6x10 tiles (this is a mistake in the clip, sorry)

Beam pipe shielding

The two pieces of beam pipe shielding, one on each side of the detector and situated between the two big Muon Spectrometer wheels, are identical and each consist of 138 pieces.

Scales

The two scales are thought to be a simple guide to the eye and to help to identify the approximate size of individual parts. Each brick represents roughly a length of half a meter.

The horizontal scale, reflecting a length of about 45 meters, is made of these pieces:

Description	Quantity
red brick 2x2 round	36
white brick 2x2 round	45
yellow brick 2x2 round	9

in total five yellow marks
every fifth red brick is replace by a yellow one
ten bricks represent a height of roughly five meters

The vertical scale, reflecting a height of about 25 meters, is made of these pieces:

Description	Quantity
red brick 2x2 round	20
white brick 1x2 round	1
white brick 2x2 round	24
yellow brick 2x2 round	5

in total nine yellow marks
the lowest white round brick is replace by a 1x2 brick to connect the scale to the feet of the model

'Recycling'

All orders (made through ATLAS) include a little safety margin for each kind of brick. Since I have some more ideas for (particle) physics related models, it would be great if you could, after you have finished your construction, send your unused/remaining pieces to me (see contact details below).
Thanks a lot in advance!!!

Posters & Labels

The poster illustrates the various sub-detectors of ATLAS and creates a nice connection between the real experiment and the model.

poster

These labels provide some basic information about the model and links to both the ATLAS and the model web site and should be place visible next to the model when displaying it.
