Powering a Particle Accelerator
Вставка
- Опубліковано 10 сер 2016
- How do you power a particle accelerator firing beams of protons 50 times a second into a heavy metal target? The ISIS neutron and muon source provides a near constant stream of particles for a huge range of research uses. Take a look at what it takes to keep a decades-old particle accelerator running.

Building up enough power in a proton beam to pull neutrons out of atoms requires a huge amount of energy. To efficiently power the machines, the research facility at ISIS relies on a custom electrical system that uses a resonance circuit to establish the strong magnetic fields needed many times per second. This system, however, is built in-part around rigid technology that was inherited from a previous machine when ISIS was built.
We take a look at the major engineering project to upgrade the power system of a particle accelerator, and see what it takes to keep control of a machine this complex.
ISIS is owned and operated by the UK government, through the Science and Technology Facilities Council, as a major resource and facility for UK researchers. This video is supported by the Science and Technology Facilities Council.

the maintenance and electrical engineering side of things are usually not talked about. What a great addition!
That was great but I wish it was about 3 times longer. I was really enjoying learning the little details. Maybe a directors cut for the super geeky?
What is sad is that people think of terrorists when they here ISIS, wouldn't be great if they think of particle accelerator?
Imagine you were one of the many women called Isis? That's why I wish news channels would start calling that group daesh or just 'terrorist scum' rather than legitimising them with a name. It's weird, you never hear North Korea referred to as the DPRK but the news will always give courtesy to daesh.
They do now
Friend: What do you do for a job?
Me: I work for ISIS
i used to go to a summer day camp called ices
I understand it's a joke but what they've done isn't funny and i think those who have been killed by them deserve a little respect. I'm not saying anything i simply just wanted to point that out.
Lest we forget...
International Secret Intelligence Service (ISIS)
HIIIGHWAY TO THEEE... DANGER ZOOONE!!!

Get used to people like me too....

You're not the only in the world with an opinion.
This is pretty incredible outreach. High quality for sure. Well done RI!
Absolutely fascinating!

Really awesome segment.
Thanks for the tour.
Great Video!
Thankyou for posting! wow!
6:50 My dad worked for 25 years at an oil refinery. He would really understand this. He called it "turn over" Basically on a regular basis (every 5 years or so) they shut the refinery down and fixed everything. It was a VERY busy time.
I love the video, I wish you could do more of these!
Thanks! We've got a few more short films like this coming in the next month or two, so keep your eyes out :)
I wish they explained a little more about the electrical system. Are they essentially using a 50Hz tank (LC resonator) circuit for each magnet's power supply?
what is the old choke called, I wanted to know more about it?
How many g's do the protons feel as they go around at top speed?
Upgrade old tech, good work Ri...
Pretty cool.
So i imagine the users at the end of the beam lines are share holders? Haha
If I were them I'd probably change the name or reshuffle that acronym. Otherwise I'd love to find them online but I'm afraid to Google it....
I wish I can work in such places.
How come I have never heard of this accelerator before? It sounds and seems very complicated, yet very useful. Great video!
What is used for ?
Its quite tragic that they are named ISIS. It's not particularly in good taste in these current days
Unfortunate, yes, but they shouldn't have to change when the name or acronym has existed in all its innocent forms for hundreds of years.
Hello royal institutions my Name is hardik I wanna ask you Question that how a proton is produced
I will expect that you will give me a reply as soon as you can
thank you
Great Expectations.
3:46 Looks like they tricked those people telling that they are going to take photos by rather took the videos
I don't understand how they isolate protons, like where do they get the protons.? how do they separate protons from an atom.?
df same
Ionized hydrogen.
Jess Stuart so that take away the electron from hydrogen.? Is ionized hydrogen the exact same as just a single a proton in a vacuum , or is there something different that I'm missing.?
Audio isn't synched with the video. :/
You might not want to mention where you work while passing through an airport. Seriously though, why shoot protons into a heavy metal, instead of shooting deuterium into tritium? Although the deuterium atoms are harder to accelerate than protons because of their heavier mass, the deuterium-tritium collisions produce lots of neutrons.
Maybe it is because tritium is much more expensive? Also I think it it would be very hard to contain a gas as a target for particles to hit
+Tat Wong, you can implant tritium inside a solid target. I have worked with neutron generators that used the deuterium tritium collisions. Though, these were small linear accelerators.
Hi, thanks for the comment - spallation is the process used to generate the neutrons because ISIS is a fast pulsed machine - meaning they can create a time structure of the neutrons which is useful for studying all kinds of dynamic processes.
D-T neutron generators are widely used in industry, see en.wikipedia.org/wiki/Neutron_generator, but they are just not powerful enough to be used to study materials at the atomic scale. ISIS produces more than a million times more neutrons.
Originally a uranium target was used but there were problems with the uranium covering distorting and affecting the cooling circuits. Spallation generated 30 neutrons per proton. Subsequently due to the cost of replacing the uranium targets tungsten or tantalum was used. The neutrons per proton was considerably less. Remember the target is subject to 100KW of power that has to be removed!
this is a high tech factory
I wonder on how many government lists I will land on by saying that I want to join ISIS now?
Don't let it blow up wouldn't want any metahumans running around lol #theflash
Phoenix ikr
Whose bum uncle that lives under the bridge synced the sound for this clip?
The Royal Institution: We will teach your kids that ISIS is cool!
This should've given a brief amount of attention to the results of the science involved. What does "save babies" and "make better airplanes" mean - something slightly less broad?
Quite. A very surprising sweeping claim with no hint of justification offered. More in the spirit of advertising than public understanding of science.
It has to be broad; such research isn't done for a specific application, but for a more complete understanding of our reality. This naturally leads to improvements in a multitude of fields and an incalculable number of applications. Though a lot of those advances happen years or decades after the research is conducted.
+Krk Patterson Thanks for your comment! There's lots of information about some of the great science research that goes on at the facility on their webpage here if you'd like to know more: www.isis.stfc.ac.uk/science/science.html
With this film we wanted to focus on the often-neglected practical and engineering aspects of the accelerator itself, but keep an eye out for the other films and lectures in this series over the next few weeks for some more detail on a few direct impacts of the science associated with particle accelerators, and their impact for society :)
So what is the goal or goals of Isis do they have different interests and experiments than other particle accelerators?
Does the Islamic State know what you are doing?
Please change name to something else
No, they were here first
How many Muslims high five your engineers, while walking outside with those Black ISIS t-shirts?
Good job you don't need to rely on charitable donations for this project. Would be an interesting experiment on the public reaction to people walking down the high street with buckets asking for support for ISIS, they need a new choke.
or.. *EAT A TON OF BEANS!*
