UK, Katie, Chris Russo discussed on The Naked Scientists
Sorry to Button Katie here from the naked scientists. Did you know we make other naked to the fraction of all humanity? Who has actually gotten a chance to see their own? Brain is very tiny and you are welcomed to that club. So if you enjoy musing over the mind reflecting on thought ought frankly you feel bamboozled by the brain checkout naked neuroscience blow? My face hurts now. So we don't go down into the creepy seller and turn the light on exactly access the full archive by a naked scientists dot com slash neuroscience subscribed to naked neuroscience. Wherever you get your podcast on the way new powers for the UK to regulate social media and our in depth look into prostate cancer now from very high altitudes to very high energies. Scientists have unlocked the next stage in the cutting edge that is experimental physics. This is an to facilities like the large Hadron collider where beams of tiny particles race around nearly the speed of light and then smashed into each other to reveal what they're made of the results shed light on the fundamental nature of the universe. The experiment is next step. Though is to up the ante using mules. These are essentially heavy electrons. Which can be collided at even higher energies but these have been very hard to make into a focused beam now. An international collaboration has managed to create that beam in what they call them you on is Asian cooling experiment or mice. I got some concise mice advice from research leader Chris Rogers. We've demonstrated a technique whereby we can take him of particles called Megan's we can squeeze them right down and accelerate them to really high energies because of the unique properties of millions. We can actually explore physics. Which is even beyond the scale which is available in the large Hadron Collider. Wow this is real futuristic. Yeah right that said An. No-one's developed a technique like this before which can really be used to handle moonbeams what exactly is immune to start with so it is like a really heavy electron have meals going through you pretty much. Every second of every day which come from cosmic rays. I've immune to me right now. That's pretty much right. What do they look like? Just like electrons except for a couple of special properties one. Is there much heavier than electrons. Almost two hundred times heavier than electrons and the other one is that they decay radioactively so they only live to millions of a second. That's bizarre. How'd you even deal with them? We have a special trick. Us leave if you accelerate particles to really high speeds as the particles get closer and closer to the speed of light. They live longer and longer. His Einstein's time dilation phenomenon. How do you make them you on your lap? We take a beam of protons accelerate those protons and then bash them into a target all sorts of other particles. Come out and some of these particles immunes and how have you been trying to deal with them in this particular experiment because the first time you've managed to get them into a beam correct? We've had millions in a beam before but we've never really managed to prepare a beam so that it would be suitable to accelerate them much more like a laser beam. If you like. We passed that meal and beam through absorbing medium and as the mules go through the absorb. They lose energy all of that hot gas slows down as it goes really absorb so then. We need to accelerate that being back up using a conventional. accelerates technique. What's this material? You're filtering them through. Is it something special in strange? We use I. The liquid hydrogen cooled down to a few tens of Kelvin always lithium metal with hydrogen embedded into the metal. Those are strange and weird. They're pretty cool. Bits of kit which we used to do it. Why does win? The meal ones go through the absorb they not the electrons of the atoms and when we not the electrons off the millions lose energy. That's what's called ionization. And that's why the techniques called on is Asian cooling. Now there's another thing which happens. They bashed into the center of the nucleus. And they scatter off flying off in all sorts of different durations. Now we don't want that so we have to pick special materials where the nucleus of the atom is as smooth as it possibly can be. Hydrogen has the smallest nucleus of any material and lithium has a pretty small nucleus as well. Is that why? It's taken so long to figure this out because you're trying to get materials with small enough nuclear nuclei nucleus Ukiah Nuclei. It's not just the material which we have to consider. We have to combine that with a possibly accelerator. Lattice and combining those two different things into one experiment was really tricky. What did it feel like when you finally managed it for the first time it was pretty cool? In fact we only cooled the beam by about ten percent of the full cooling channel which you would need a real meal collide facility but that was pretty cool. I'm what does this mean for physics? Is there really exciting? Science coming up that could potentially use. Mu On beams. The aim of our experiment then is to take this technique and then put it into a single immune collided where we collide beams of meals together. Mueller light is a really exciting because they let us reach much higher energies than are available using even existing facilities like large Hadron collider sern a large Hadron collider upgrade. It would be a large meal and Kaleida Large Mu on collider. That's cool should be. We'll have to wait and see what happens. When they try it Chris Russo from the Brotherhood appleton laboratory discussing the experiment. They call mice and which was published in the journal Nature. We're heading back in time because Adam Murphy's been looking at some cracking cutting edge science using eggshells to take a dinosaurs temperature Jurassic. Park is.
