Top quark accelerator
Sorry, honey, you'll have to find another bowl for the nachos. Oh, and I used the last of the top quarks in the fridge.
About this creation
Please feel free to look over the images and skip the verbiage.

What can you make with a nacho bowl, a powerful pull-back top spinner, an 8L axle, and the right LEGOŽ tire and wheel?



What else? A DIY single top quark accelerator! Ah, the sweet whine of a lone top quark on the fly!

Warning! Always wear eye protection when working or playing with high-speed LEGOŽ rotating machinery and keep valuables and bystanders (including pets) a safe distance away -- especially when testing new designs. Really.

Revatron
The latest LEGOŽ pull-back motor (12787c01) powers the reversible white and DGB Revatron at the heart of the accelerator.





The Revatron's ability to send top quarks flying around the ring in either direction will be the basis for a much-anticipated top quark collider.



It also comes in handy in reversible flying LEGOŽ rotor launchers.



Top quark
The top quark appears only as a fleeting condensation of matter in the aftermath of some of the most energetic particle interactions man can create and is not a constituent of ordinary matter. It was predicted by Kobayashi and Maskawa in 1973 and first observed by Fermilab researchers some 20 years later.

The top is the most massive elementary particle known. It's ~39% heavier than the famed Higgs boson and ~40 times more massive than the next in line.

Importantly, the top is the only quark known to exist singly -- i.e., outside the confines of a hadron like the proton or neutron. Otherwise, a top quark accelerator would be just plain silly!

To us, a top quark looks just like this:



But I think it might look like this up close:



After extensive testing, I found this ZR tire and wheel and a plain old 8L cross-axle to be just the ticket for closing the gap on the speed of light -- which is of course the best an accelerator designer can hope for.

I get closest to the limit when the rotor's a little closer to the tip.

Quoting Nils O. I think we need to add another warning: It's so much fun, it should be forbidden! :-)) As I always say: Engineers are just (more or less) grown up little boys. And that's what I am and I never want to be anything else :-))
That makes 2 of us, Nils, and I couldn't have said it better! Engineers play with the physical world. I get those kicks through LEGO.

Quoting Nils O. I've just made a simplified accelerator with one of these pullback motors and it works ... too good! :-o I have to hide it from my son because it accelerates the tops so much that parts start flying around the place. My favorite one is a micro top (just a 2L Technic axle, a 2x2 round plate and a 2x2 round slider), but it gets so fast that it starts "shooting" the axle away. I also have to be sure to have a gap between the spinning top and the accelerator. Otherwise the friction and speed create heat that starts melting the plastic part that gets in touch with the accelerator. It's much fun, but I think that eye protection is not a bad idea when we play with it :-))
Thanks, Nils! I'll have to try one of those micro-tops. Wow, I thought I had a good feel for that pull-back motor's power, but I never imaged melting plastic! I've uploaded dozens of LEGO gizmos with parts that spin at high speed. Some already carry safety warnings, but you're absolutely right -- there should be safety warnings on =all= of them. Just added one to this page for starters.

Quoting Oliver Becker Excellent, Jeremy! And so good the nachos were allready eaten up... ;)
Thanks, Oliver! Yeah, the #1 rule of particle accelerators: Particle beams and nachos just don't mix. ;^}

Quoting Topsy Creatori Okay, I'll be waiting for the verbage explaining the sweet whine of that quarky top on the fly!! ;)
Always a pleasure to hear from you, Topsy! Yeah, that was sweet whine thing was pretty obscure. I like the whine of high-speed machinery driven by electric motors -- especially at amusement parks. The accelerator makes a faint version of that whine as the tire rolls around the bowl at high speed, and the sound makes the accelerator look even faster. The background noise that day made the whines hard to hear, but the last one is the easiest to pick out. Have you moved to Flickr?

Quoting Nils O. Very cool, now I know what I can build with that pullback motor I have laying around... Great job! :-))
Thanks, Nils! I think you'll find the torque and speed of the latest pullbacks quite impressive. Lots of potential play value.

Quoting Scott Bertaut I'm afraid all the science stuff went over my head, but looking at this makes me realize it wouldn't be too hard to make some LEGO Bayblade tops battle!
Thanks, Scott! Absolutely, and the best tip for a battle top is usually just the bare end of a cross-axle. If you make some battle tops, please let us see them!

Quoting Nick Barrett Looking forward to the Large Top Quark Collider.... fascinating stuff.
Thanks, Nick! Unfortunately, the collider has run into a snag. I applied for a permit to dig the necessary circular trench in the back yard, but my wife turned it down flat.

Too kind, Oran! That's what having too much time on your hands can do to a brain if you let it.

Quoting David Roberts Thank goodness for the video! The opening text left me utterly befuddled! What great fun, though I think I'd want to be wearing my glasses in case a quark was to come flying out of the bowl. Great fun and very original.
Thanks, David! Amazing the energy you can store in a pull-back motor! Unfortunately, containment failures are fairly common with this thing. One top quark even flew straight off the deck and into the yard. Good thing I had the sense not to go for an anti-top quark accelerator. That could have gotten messy in a hurry!
