560 pieces.
In fall 2011, I have designed a model of the ATLAS experiment made entirely of LEGO bricks.
It illustrates all details, from the muon and magnet system to the innermost pixel detector and will hopefully be a great eye-catcher for all generations. Here's some key features:
ATLAS LEGO model
about 9500 pieces
roughly 1:50 in scale
(close to scale with the LEGO man)
material cost of about 2000 Euros
(payed by the high energy physics group at the Niels Bohr Institute)
about 1 m x 0.5 m x 0.5 m in size
approximately 33 hours construction time
(spread out over several weekends and after hours)
around 48 hours to build the 3D model
(a one-timer though)
As a follow up to the 1:50 model, I also designed a smaller and cheaper miniature model in LEGO bricks.
Though it does not illustrate all details, the key features of ATLAS are visible. Here's some key features:
ATLAS LEGO mini
560 pieces
roughly 1:2000 in scale
material cost of about 75 Euros
about 22 cm x 11 cm x 11 cm in size
approximately 90 minutes construction time
around 7 hours to build the 3D model
(a one-timer though)
