[@thedayb4tomorrow]

I did my PhD on MICE and this is the first time I've heard what we were doing referred to as "super cooling". 🙂 Basically we send the beam through a low-Z absorber (liquid hydrogen or lithium hydride) and the muons lose energy by ionizing the absorber molecules. low-Z is important to minimize scattering. Was awesome to see an experiment as small as mine (only about 60 people at any given time) on SciShow though 🙂

[@Jake20111]

The (original) photo in the thumbnail is from within ProtoDUNE. There were 2 of these prototype detectors hosted at CERN which used 2 slightly different Time Projection Chamber readout technologies. The so-called 'Single Phase' version was injected with a charged hadron beam. Analysis of this data is ongoing. Additionally, a small correction to how DUNE's detectors (Liquid Argon Time Projection Chambers) work. Yes, the neutrinos will exchange a W or Z boson with the argon and some interaction products will be emitted. However, it's not just electrons which will be detected. Other charged particles will in fact ionize some of the other argon in the detector. The electrons from this ionization process are what will be read out by the detector (not actually the electrons produced directly by the neutrino-argon interaction and the subsequent shower).

[@pauldavis2108]

I got to finally tour protodune last summer after watching it's construction over several years. Pretty cool stuff.

[@nurfuerdieplaylist]

I think they are saying just what you're correcting, only worded a bit less precise. At 9:53, "THOSE particles" is referring to the "particle shower" from the collison of argon with the boson from the initial argon-neutrino interaction, if I understand that correctly :)

[@Jake20111]

@@nurfuerdieplaylist 'those particles' referring to the electron shower constituents are disctinct from the electrons ionized from the argon when a charged particle passes by (including the electrons in the shower -- 'those particles' -- as well as other charged particles like protons or pions).

[@Descriptor413]

Good video! A few corrections, though: 1. 1:40 Magnetic fields don't accelerate charged particles, electric fields do, generally through the use of resonating RF cavities. Magnetic fields can only deflect the particles in a direction perpendicular to the field and the direction that the particle is already going (which is how they are used for steering the beam, as you allude to later on). 2. 3:17 While not needing steering magnets is one reason for not using a ring shaped accelerator, there's actually a much bigger reason to use a linear accelerator! The real issue is something called synchrotron radiation, which is light emitted from charged particles that are going at relativistic speeds and then bumped in a direction that not the one they're already going in, which is what is constantly happening in a ring accelerator (since the magnets are always trying to force the beam to bend). This synchrotron radiation causes the beam to lose energy, and thus speed, which is kinda the opposite of what you want your accelerator to do. Plus it creates tons of X-rays and other high energy photons, which can be quite the mess to deal with in the accelerator tunnels! (Side note, this phenomena is actually also used as a purposeful source of X-rays in some experiments, in what are called Synchrotron Light Sources). The reason we can still use ring accelerators is because protons don't put off too much synchrotron radiation, so you can still reasonably come out ahead with achievable accelerator voltages to get up to near the speed of light without issue. This is why most (if not all) ring accelerators only deal with protons and anti-protons. The problem is that when you're trying to do stuff with electrons, they produce way more synchrotron radiation, so the only way you can accelerate them to where you need to go is by using linear accelerators, which don't need to bend the beam continuously (beyond some mild correction). And that's what the ILC hopes to achieve! 3. 8:34 The real reason the neutrinos are being made in IL but measured in SD is because it's cheaper that way for tax reasons. (This one's a joke) Still, glad to see your channel put stuff like this out there for folks! There's a lot of nuance with these things, so no worries about missing a few details. I certainly wouldn't have known any better since starting my job at Fermilab a year ago, so the details don't matter too much if you're not actively working on these things. Still, I figured I would add a few tidbits for those interested!

Particle physicist here - I don't think I've heard "moo-on" before aha, typically people use "myoo-on" like the greek letter. More interestingly with regard to a muon collider, the other big engineering constraint is that muons decay in microseconds. You can extend this relativistically when you speed them up, but you can't escape it, so you have a ticking clock from the time you create the muons to the time you collide them. The LHC currently takes hours from injection to collision, so this would be a significant design difference, though it should still be possible. A muon collider would be really, really exciting.

[@sharrpshooter1]

I can't believe they didnt even mention how insane it is to use 17 ton of liquid argon. For anyone who doesn't know, liquid argon can only exist between 83-87 K (-308F to -302F), thats an insanely tight band, and while they can use liquid nitrogen, its gonna be insanely hard to even get that much liquid argon in there and keep it that cold

[@MariaMartinez-researcher]

10:40. The first episode of the Star Trek Original Series dealing with parallel universes (nowadays a staple of the franchise) was The Alternative Factor (1967), and precisely was about a guy from an antimatter universe pursuing his twin from the matter universe, because... of course, if the guys ever met, that would be the end of both universes. Pretty advanced sci-fi concept for the time, unfortunately botched by the episode's execution. That happened because the actor who was signed to play the dual role of the matter-antimatter guy didn't show up, and the production had to get anyone the same size and willing to get to work on that very same day. They did, but the poor guy they got (they caught him at his birthday party), despite being a fine actor, simply had no time to figure out the complex role and as production was already delayed they couldn't stop to rehearse scenes or reshoot to improve the performances. It's one of the worst episodes of the franchise. Still, it's worth a watch, because the concept is still modern (as this video proves) and the dramatic resolution is harrowing.

[@johnpekkala6941]

For electrons and positrons a linear collider is the only viable solution as electrons and positrons loose too much energy in syncrotron machines like LHC. For ex the LEP (Large Electron Posotron Collider) wich was the machine before LHC housed in the same tunnel between 1989-2000 could only reach around 180 MeV (0.18 TeV) compared to LHC reaching 7 TeV with protons. However the Tevatron at Fermilab could bring them up to at least close to a TeV and the Tevatron rings were smaller then the LEP wich was same size as LHC so it might be some differences in the machines also apart from this fact. (One thing was that the Tevatron was superconducting and LEP was not) The issue with linear accelerators however is that to reach high energies with one single pass through the machine something way more powerful then todays RF based acceleration systems are needed. Things like plasma wakefield systems and similar could generate many times the accelerating field of todays RF based machines and thus making a multi TeV linac a reality. CERN are currently working on a project called AWAKE ( Advanced Proton Driven Plasma Wakefield Acceleration Experiment) that aims to develop a such system. Then we have muon accelerators.The best of both worlds but there is one more issue not taken up here regarding muon accelerators. Muons, just like higgs bosons and other super heavy particles only exist for a few billions of a second after they have been created. That means you have a VERY short time to create, accelerate and collide the muons before they cease to exist. The muon cooling system is there to adress that problem as well so that you will have enough time with the muons to be able to use them in an accelerator.

Yes, DUNE will also be great, but it feel a bit odd to call it a "New Kind Of Particle Accelerator." I highly recommend this delightful video from the T2K collaboration! kzbin.info/www/bejne/q164eWZ7rK54f9U (Of course, electron-positron colliders aren't new either.)

I never understood why they don't just stack multiple smaller rings on top of each other to achieve the same effect. since the particles are held in place magnetically, the verticality shouldn't be an issue and it should allow for more precise calculations due to the lack of localized gravitational differences... right?

shortened version: please tell me what ocean acidification is and how it impacts our own lives.

[@philcoombes2538]

more CO2 dissolves in seaH2O --> more carbonic acid H2CO3 - greater acidity...

[@jl9088]

@@philcoombes2538 and the more acidity means more Hydrogen which fuse with carbon also decreasing calcium carbonate causing the marine animals to start struggling. Is that why ocean acidification is a problem?

Hi Stefan!

...what kind of magical rare coffee is this that cools down on the order of hours rather than minutes?!

[@alans5799]

what is the name of the fcc detector(s)? Long island is about to fire up the sphenix 'super phoenix' detector at rhic bnl

I can only recommend the Video series on the SSC Project of the 90s in the US by Bobby broccoli on KZbin Its so interesting and packed with Info about physics, politics and how they intertwined

[@TheBeelzboss]

I'm wondering if it would be helpful at all to build one of these in space or not... I know it would drive the price up exponentially, but would it be worth it at all?

[@therobot1080]

Nope. Gravity's influence on these experiments is basically nonexistent. (Literally the weakest force, what can ya expect)

[@mohhie]

- i bet you cant incorporate stock image of a radio and coffee into your script - hold my standard model

[@Ambryu1]

How deep does the rabbit hole go? geesh.

[@OmegaMegalodon]

I don't think I will live long enough to see the fruits and new inventions resulting from Particle Physics and Quantum Research. It would take another few hundred years to see the progress, now we barely scratch the surface.

[@jollyjokress3852]

I recently saw a show where it was claimed that a larger particle collider is likely to be realized in China.

[@florinadrian5174]

I thought the Higgs field gives mass to other particles, not the Higgs boson. Am I wrong?

[@garethdean6382]

No, you're correct, the video is being simplistic.

[@bigjay875]

Well that explains why argon has gotten so expensive to buy for shielding gas when welding

[@melody3741]

Neutrino always sounds to me like something that Ned Flanders would say

[@HeckaZecka]

I bet one day there’ll be one that goes around the whole Earth

[@CozyJoney]

The Cern Future Circular Collider should center around Liechtenstein 😂

[@nicokra7602]

the location of the LHC is wrong. at 2:33 it is next to Saleve, at 5:48 it is fully in France partly under the Saleve. In fact the location is much more in the north-west, next to Jura (neary Meyrin/Saint-Genis / Segny/Ferney). Are the proposed locations of FCC and CLIC correct?

[@CudaWudaShuda365]

Should be built in Britain because that's smashing

[@ravigm6515]

Electric field is used to accelerated the particles, Magnetic field is used to steer them but not accelerate them.

[@stax6092]

Cool.

[@EmilyJelassi]

I started out sort of understanding this, but could feel my eyes glaze over the further along the video went.. ended up incredibly confused

[@FM-kl7oc]

8:33 Thought you said "doom" at first.. 😅
