Accelerator Science: Luminosity vs. Energy
HTML-код
- Опубликовано: 8 июн 2024
- In the world of high energy physics there are several parameters that are important when one constructs a particle accelerator. Two crucial ones are the energy of the beam and the luminosity, which is another word for the number of particles in the beam. In this video, Fermilab’s Dr. Don Lincoln explains the differences and the pros and cons. He even works in an unexpected sporting event.

Pixar called, they want their CGI wizard back...
But seriously though, your science videos are a great service to humanity.
ⴰⵣⵓⵍ ⴼⴻⵍⵍ-ⴰⴽ !
Don created some dank memes in this video. Totally worth the CGI budget.
Dr. Don Lincoln is becoming more and more creative with these. And I'm loving it.
Insightful content and very well explained :)
this is the best video you did so far :) thank you for your funny and enternaing aproach of bringing your research closer to society! looking forward to see more amazing sience videos! ( give this man a higher budget )
Completely agree. It was awesome, even more for a particle-physics-researcher wannabe like me :D
Man, I love this videos XD
I love this video! Huge thanks to Fermilab and Don!
I just want you to know that this Video series has been very helpful learning the more advanced concepts of particle accelerators and particle physics. Great work!
Awesome stuff! Thanks for making my days better, Fermilab!
Yay, a new Fermilab vid :)
Hahaha I definitely think this is one of Dr. Lincoln's best videos. It was pretty intense.
Don, I love your videos. Please continue the great work!
Such a difference to hearing someone talk about this that actually works there.
I have watched maybe 10 of these videos in a row and many long term questions and curiosity's have been answered.
No mention of weather control yet :D
I like the wires around the door frame more than the strange horse poster. The luminosity of information was good as well. One tidbit explained energetically is hit or likely missed in my brain memory parts. Thanks for the video!
I don't have words to appriciate the presentation!.. its way too good!!
Finally I get to sit down and learn somemore! Thank you!
Mind blowing way of explaining!!Thanks a lot.
I love this channel and fermilab , thank u for all the videos because it fuels the curiosity for citizen scientists
While I wish you guys the very best, I love that this channel is like a hidden gem :)
Dr. Lincoln, that's been your most entertaining of your videos, about High Energy physics.I finally start to like that stuff. Even as a Solid State physicist.. THX
Thank you ! I've been waiting for this one :D
Great videos.
A truly interesting new approach to teaching these videos! CGI graphics unquestionably makes things easier. I've also employed subtle humor in my lectures. Beware, a little can go a long way haha!
Hey guys, nice video. Though i have tip: make it more information dense. It took 9 minutes, where i would've loved to watch it twice in that time. Now it feels like you're trying to hard to make people interested. We watching already are ;) Thanks for being on RUclips! Chears and keep it up
Another great one. I would like to see a video on the measurement problem and Schrodinger's equation.
Really appreciate your videos. I laughed and learned a lot. Keep on rockin' :)
awesome effects
We need more Don Lincoln....more luminosity!
Great video
I am a fan of yours.
Yay! I love this channel!
Good message... Don't even let the insane game be played! :)
Dr. Lincoln is the honest Abe to my love of science.
BTW, was that a Higgs Bison bucket???
I love puns and I am a geek! ;-) and I love awards!
We want more video about luminosity PLEASE
not my kind of jokes, but still love his Videos. well done.
Ayy more science!
Kudos for the funny vid! deserves more views
These videos are great. Thanks, Dr. Lincoln
good vid
Who does the theme music for these videos and where can I hear more?
Aqui todos hablan ingles pero yo soy de habla hispana jajaja I love your videos.
So here is other question, having high energy particles is one thing, but Big Bang epoch also had much smaller special distance which the accelerators can not replicate. Is this statement true? If it is, then only the major gravity source can warp space enough to contract space. It's that spatial contraction statement with respect to massive gravity true?
Nuclear fission with your hands. Impressive!
I like the introduction of animation and additional people into these videos. I suggest, however, adding more information and details about the physics and terminology. Channels like PBS SpaceTime, for example, often go way over my head, but I don't mind the challenge. Obviously I can only speak for myself, so if the producers decide to stick with the current target audience, that's OK. I still find the videos enjoyable.
I feel genuinely honored to be only 1 of 620 people who have witnessed this masterpiece.
I click on Fermilab notifications faster than that electric field accelerates particles.
I would love to see more videos that go into greater detail about these topics.
Obviously we are not all experts in the field of theoretical physics, but if we are coming to this channel, we most likely have some sort of grasp of this topic. I say leave the comedy to the professionals, because it seemed just a bit "cringy" to be perfectly honest. I would love to see videos where the basics of the mathematics are explained as well. It would be nice to see someone who could actually describe the sort of math that it takes to figure out such problems without going into the details of solving all of Quantum Mechanics. This is just a friendly suggestion, because all in all I really enjoy your videos and am glad you create them. The universe is an amazing place and there are many of us who want to know as much about it as we can, but perhaps are not as gifted mathematically as we are conceptually.
+ScienceNinjaDude One possibility would be to continue making videos at this level, but to sometimes add supplementary videos on the same subject with more detail, sort of like an appendix in a popular science book.
*****
Of course videos cost money. I merely suggested that it might sometimes be worthwhile to spend some of that money explaining things in more depth.
One of the big problems with popular accounts of things like QM is that too often important results such as the uncertainty principle are presented as if they were pulled from someone's rear end; they appear to the reader or viewer as entirely arbitrary things that were just made up, so they can just as easily be rejected by the skeptical reader/viewer. More needs to be done to show that these sometimes bizarre things have solid foundations, and are not just the result of someone's bad acid trip.
I am not claiming that I know how to do this at an appropriate level, or that it would be easy, but more needs to be done.
IS the particle's energy increased by accelerating it? Or is there something else to it.
Woulden't it make it harder to analyze, interpret and confirm data aswell as increase the probability of errors?
Could you increase luminosity by accelerating higher mass atomic nuclei?
how do you get individual protons isolated? i assume you dont pick them out with your fingers
Of course he doesn't. They use tongs
As of early 2018, luminosity seems to be winning. Energy might've won the round for the Higgs, but the top hints for new physics are all from luminosity (at least if you consider precision physics part of it).
1) LHCb b meson decay anomalies
2) T2K experiment finding initial signs of very large CP violation in antineutrinos
3) Hints of 4th, "sterile" neutrino in some experiments but not others
4) Claimed discovery of new, 17 Mev boson in Beryllium radioactive decays that's awaiting replication. Jefferson lab hosts the one experiment looking to replicate that I'm aware of, Darklight, which is a precision high luminosity approach that should have results within a year or so.
5) g-2 anomaly, which Femilab itself is leading a flagship experiment to confirm.
All of those are results from lower energy, high LUMINOSITY experiments. What hurts the main LHC- and Tevatron before it- is that while the proton beams might get up to say 6 TeV of energy, the # of actual collision EVENTS with even 5 TeV is infinitesimal. The proton being a messy spitwad of gluons and quarks means the vast bulk of collision interactions feature almost all the energy going into the production of pedestrian subatomic shrapnel, not the new force carriers or matter particles you're looking for (e.g the Higgs itself). It's looking like luminosity will indirectly discover the presence of new physics, a new"something", then big colliders like the LHC will be tasked with nailing down what that "something" can be by either producing the new particles posited to explain the effects or not.
Can someone explain, that if in core of very large star that heavier atoms formed rapidly, then why in initial Big Bang short time wouldn't a fairly significant percentage of heavier atoms have formed? Why just mostly hydrogen and helium and not the heavier atoms? The pressure and temperatures would have been that of the centers of large stars wouldn't they have been? The large stars burn themselves out so quickly so wouldn't Big Bang have been able to rapidly generate heavy atoms too quickly?
I feel like this will be the tapes I find if I am ever LOST
could the electric field animation be more descriptive next time? like a group of arrows might be a more useful depiction
I'm favoring luminosity to energy. I don't have a multi-million dollar particle accelerator but I do have bricks and a sling and they contain a hell lot more protons that what you put into yours.
Also, I hope I can one time prove you can quantum tunnel a brick through a wall.
I'd wish to be 35 years younger to study physics and be specialized in particle physics to be able to demonstrate that loop quantum gravity is the connection between quantum mechanics and general relativity
Hey, if I had the materials, I could maybe build a homemade particle accelerator in my backyard!
And a most cinematic of vids. !
So what you're saying is that the result of the contest between energy and luminosity can't be known until one of them measures a new result? How quantum.
Question: what would happen with electrons in a electric field?
But in the same direction?
Can you theoretically split protons and electrons if the electric force is strong enough?
Nice
why cant all physics lectures be like this!
😂
One day I will be able to rock that shirt like Dr. Don Lincoln 👍
This is like "THINKING OUT OF THE BOX"....
The box is ..THE UNIVERSE.!!
Waaaaaaaw
wait wait!!! lottery tickets ... or scantron sheets XD
Particle Accelerators: Most Expensive Gacha Game
In the context of particle accelerators, aren't you really talking about intensity, rather than luminosity? Isn't luminosity a product of intensity and the detector upon which it is directed?
+ScienceNinjaDude What is the density of the audience target?
Dunno - But, I'm pretty dense.
*****
I rewrote my comment several times to try to get rid of the implication that the audience members were dense. In particular, I changed "target audience" to "audience target", and "how dense" to "what is the density", trying to suggest that the answer should be in audience members per square centimeter or something like that.
Clearly I failed, and the pun was not worth the confusion.
*****
Thanks. I just didn't want to insult anyone.
+1 for cheesieness 😂
can you proove time travel is impossible?
You travel *forwards* through time, second-by-second. Time travel is very possible, even inevitable. You probably meant backwards in time.
You can prove to yourself how unrealistic it is by taking a physics course. One way to travel backwards in time would be by exceeding the speed of light. But when you learn general relativity, you'll see what happens when you accelerate an object. It doesn't matter how much energy you put in, you'll never even get to the speed of light.
This is a great channel. You really don't need visual gimmicks. Maybe for the mindless, but they are about as likely to come here, as a boson is to jump out of this peanut and bitch slap me. Visual's are ok, but please just don't make them look like they are for 10 year olds.
So the rare thing is that a particle we don't know could magically appear? What is the "rare thing" happening?! How do we know there's a "rare thing"?! Good video, but be more clear.
The rare things are just reactions that have a low probability of happening. Typically, when you slam two things together there are a number of possible reactions that could happen. But they don't happen with equal probability. Obviously, to see the less likely reactions, you have to do a lot more slamming than you have to do to see the more likely reactions.
who would win in a fight.. you or bill nye? 😂🤣😂🤣
Very educational video, although, no offense intended, he isn't the best actor.
lame animations... but undoubtedly AWESOME videos..
These would be better without the energy spent on trying to make them funny or entertaining. You don't do that well. You do science well and that's what we want from these. I think.
Energy is cheating , taking help from another hand
