- Uncovering the mysteries of matter, space and time requires a beam of subatomic particles. #Fermilab scientists and engineers used a complex system of magnets to create and store a beam of muons for their groundbreaking work on the Muon g-2 experiment. This allowed the team to achieve the world’s most precise measurement of the anomalous magnetic moment of the muon.

Decaying into a positron? are you using anti-muons? I understand that that would still work for the analysis, same properties just inverted.
Great catch! Yes, the Muon g-2 experiment observed antimuons (which decay into positrons). Using positive muons allowed the researchers to get approximately twice the number of muons for each incoming proton compared to if the team had used negative muons.
1:51 - I really like these plots
The animation quality is very cool
And this is a problem🤏
because no one can see the particles, they can fake the animation 🤷♀️
I love Fermilab!
Aim for the muon!
Just wanted to clarify, you're using anti-muons, right? Otherwise I don't see how charge is conserved. If so, how would you change the experiment to use regular negatively charged muons?
Great question! The Muon g-2 experiment observed antimuons because the beamline at Fermilab captured positive muons. To use negatively charged muons, the Muon g-2 team would need to swap the polarity of the magnets in the beamlines and the g-2 magnet, kickers and quadrupoles. But, by using positive muons, the experiment was able to get approximately twice the number of muons for each incoming proton compared to if Muon g-2 had used negative muons.
@@fermilabAlso the gamma pair from e+/e- annihilation is quite the handy signature for a decay event
Thank you.
So cool!
"Inflector" is my nomination for Coolest Word in a Muon-Related Video. Also "electrostatic quadrupole" is a great insult.
nah, "pi-on" wins. who ever heard of a pi-on? 🤯
Well, that's rad.
Very insightful
Hi, may I ask you the perimeter that the beam travels ? 30m? 40m? Thank you.
Frontline assembly, ministry, the cure, Damn mr Lehto, you have some interesting music tastes :)
So cool.
MAN! Fermilab looks a LOT like the Photon Power Laboratory from Mazinger Z
A precision level of what? The muon's energy and time of arrival?
Of the gyromagnetic ratio of the muon, i.e. the ratio between its magnetic moment and its angular momentum. It is a quantity whose value can be predicted with great accuracy: in the case of the electron, where measurements are in agreement with predictions to up to more than a part in a thousand billion (and we can't say more because that's the precision of the measurements). On the contrary, there are hints that for the muon the picture may be different from past measurements which however weren't precise enough to give a definitive result, so they need to be improved. If the anomaly was confirmed, it would prove that yet unknown physics is at work with the muon.
How many muons does it take to screw in a lightbulb?
More important question:
Who has stronger memory, a muon or a golden fish❓
@@duran9664 How is a muon like a writing desk?
@ArtDocHound people think it's a good idea to spend money on them, but then nobody uses them
Could those muons be used for fusion?
Sadly it doesn't look like so, it's been looked into repeatedly but it simply isn't energetically effective since muon production and capture ratio and muon lifetime are all so low.
I tried to make a muon beam once, but I messed up and ended up scattering the muons all over the place. What a mess to clean up. Now I just make spaghetti instead.
Fun fact, it's highly likely you are being traversed by a muon this very second. There's plenty of them produced by cosmic rays interacting with the upper atmosphere and surviving till the surface. Another easy proof of relativistic time dilation btw
@@raffaeledivora9517 you and I have a different definition of fun. I'm getting too old to keep up with everything. I can't even remember the last time I had fun.
-what are the 20 cents for?
-to get the protons
Cool video, but where's Don?
As great as Don is, sometimes they have to show that he's not the only one with an exceptionally functional mind, and not the only one there.
@@Bob-of-Zoid Just the only one with charisma...
Ok.. and❓
What’s the end game here ❓

Can this be used as a weapon? Signed, Russia
And how to make proton beam?
In case no one posts an answer, I am going to review the documentary film Ghostbusters for clues.
How do you make a Muon beam? Tell it how you love how independent it is!!
the positively charged quadrupoles seem limited by mass unlike negatively charged poles which can be charged to the minimum breakdown voltage of the dia-electric atmosphere.
I did not catch exactly what concept you were studying or trying to improve the precision of.
How to spend all the money and still have the nerve to ask for more

It reminds me The Beach Boys song I Get Around....for some reason
Around and Around and Around
Mudfossil University has research on the muons and electon neutrinos that began in the early 70s. There is know question about this topic that can't be answered over there.
Roger’s “research” involves looking at a photo of an out of focus water droplet sprayed into the laser beam to illuminate it and thinking he is seeing an photon. Literally anyone with more than kindergarten education knows that it is utterly impossible to image a photon (thousands of times smaller than the wavelength of light and moving at 186,000 miles PER SECOND!) on an old Samsung phone camera! The best research Roger could do would be to learn how Cameras work. Once he has mastered that he should do a physics 101 course to learn the basics of the subject. Until then it is best to treat Roger’s “research” as purely for comedic entertainment.
There is zero science in anything reported in a Mudfossil University video.
Consciousness is all there is. See my paper "How Self-Reference Builds the World", author Cosmin Visan.
Let Kirsty & Don do this. They're professionals. At least we won't have that loud noisy radio playing in the backgrund
Agree - the music is just annoying and unnecessary
@@Richardincancale I propose a competition to find a presenter on par with the adorability of Don & Kirsty, but with sharper science-communication skills. I recommend Chris Clare - Chair of the Mission Committee of St Leonard's Church, Chesham-Bois.
ב''ה, looks fun, but how much are you paying Oprah and her successors and assigns for use of the circular design?
zzzzzzzzzzzzzz 😴
Weird question, so is anyone trying to model the effect of strangeness in hyperons might effect the distribution of nucleon numbers in the island of stability, and or the possibility of inferring the same from observations of neutron star glitches or ringdowns, or using muon beams to stimulate sympathetic emission of neutrinos in an attempt to influence the stability of heavy nuclei. I don't want to pay $40 per attempt to find out. Also I am a moron and can't do differential equations anyway.
*¡nothing as to how Muon G-2 subparticles interactions with others are discussed! - this CZcams AudioVideo is a complete disappointment and a complete waste of time - 8:24 am Pacific Standard Time on Wednesday, 17 January 2024
Well, the title is about how they made the tunnel, not on how they are reacting. Some troll always has to whine and cry.
@theflyfishingnomad9641 is a sycophant and apologist via educated gibberish considering that its construction was not mentioned except something internal in a superficial manner on the subparticle and what could happen inside the collider pissibly the C.E.R.N. - 9:00 pm Pacific Standard Time on Wednesday, 17 January 2024
At the end of the day you did not tell anything, lame...
Round and round in circles...
No eggs? This is not as good as a "How To" video as HowToBasic makes.
To all the particle physicists, please make a note that, all the particles of all matter of the universe are made up of pure ENERGY controlled by its own BLISS, SOUL and MIND. This is the SINGULARITY or GOD resided in the Black Holes. You may check me website for more details.
In 2024 in U.S. universities, if you say that a photon is just a lightweight electron, you'd flunk your physics course and probably be laughed out of the school despite it being the truth. They spent from 2017 until 2020 trying to use muons (which are highly evanescent and difficult to produce) to enhance fusion reactions. Starting in 2021 they started (quietly) using gluons and from there went to odderons. Information you find about physics (as we are in the midst of a global conflict) is largely disinformation, and does this surprise anyone? We need to use odderons for fusion. If you want to learn about actual physics, don't trust a word coming out of American institutions right now. See my LiveScience thread in the astronomy forum for more info on what is actually going on in physics right now.
I hope this is money spent wisely. There's still debate whether our own sun is a gas or a liquid, the sun being slightly bigger than a muon, and kinda in our face.
this is a very strange series of statements
@@WeeWeeJumbo Well, if they can't figure out if our sun is a gas or a liquid, and it's been staring us straight in the face for aeons as the largest astronomical body in our immediate vicinity, how our they ever going to undertand an esoteric particle like a muon? The LHC has been in many ways a very large waste of resources that could have been more wisely spent.
@@samuellowekey9271 Is this really a good faith argument? Who cares if we don't fully understand the sun? We don't fully understand much of anything. Just because most people understand the concepts of "gases" and "liquids" in school doesn't mean that they're fundamentally simple. Do you expect scientists to just magically categorize the sun into one of the two groups? This has nothing to do with whether or not we should build a particle collider, or any other experimental devices.
Hindsight is 20/20, and even a monster machine like the LHC is an inconsequential fraction of human resources
Worth noting, the universe isn't even objectively made up solids, liquids, gases, plasmas, etc. The universe is just made up of stuff. Our categorizations of solid, liquid, gas, etc. are ultimately arbitrary. They're just models of how the "stuff" behaves, so it's not surprising that sometimes we find objects that don't neatly fit our models. Our understanding of the states of matter actually has a track record of being revised as we discover more kinds of ways that matter can behave
