CORRECTION: At 2:18 Dr. Cryan meant to say "an attosecond is to a second as a second is to the age of the universe.", not a femtosecond.
The engineering required for this and something like the LHC is mind-blowing.
Yes it is!
Summer 2022, first image from James Webb and this! how exciting in the world of physic!
It's a big year for science! I can't wait to see what Webb shows us!
My 1st time at SLAC was in the 70's. Its great to see it is still doing cutting edge science.
As I currently work in the UK's Neutron particle accelerator @ STFC, I value this video...its simple enough for the every day person with enough information to help them learn about these sort of systems. The biggest factor is that people don't realise how many of them they are and also the differences between them. Neutron, Proton, X-rays, Muon and the different machines around the world. Many people know about LHC and may consider this to be similar which it would be good to show them where its not. Great video though. Keep up the good work!
Good news is always good. Thank you so much
This was really well done. Thanks CNET!
It's amazing, how the research conducted at SLAC, impacts all the other fields of science! Very interesting and exciting.
Cool. They chose the perfectly-stable-land locations… 😳
Amazing Laboratory of World Best X Ray Laser
"A femtosecond is to a second, what a second is to the age of the universe." WOW, that's a pretty unfathomable number. This is quite the elaborate machine, how much does it cost for a single run of this beast? The power cost alone has to be several thousand dollars per run.
14 dollars a run surprisingly
14 dollars a run surprisingly
Keep it up, nice video, thank you for sharing it :)
Great piece CNET!
Thanks!
Man that laser is so bright it burnt a hole in my screen
😎
When SLAC refers to brightness, it's important to remember that's not beam power. Brightness is actually amount of power in a subtended solid angle. Or more colloquially how tightly is the beam focused. Last I heard from project scientists, LCLS-II was under delivering design power and over filling its focusing optics. That is to say, not very bright. But maybe these are just the normal start up transients for a big project. It's important to sort out reality from hype.
Doc Cryan seems like exactly the type of person you should have down there. Hes soooo excited about this stuff.
Very impressive 🦾
Everyone in the Peninsula has a friend that works at SLAC. We know what we're driving over.
I completely understood everything in this video. 🤔
Amazing 😍
Super intéressant 🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂
Nice video 👌
Thank you 😊
Great Video
Thanks!
Thanks for watching! What do you want to know about LCLS-II? I'll do my best to answer your questions!
In the last experiment hall, there seemed to be a lot of "human exposure" within the large chamber. When it's pumped down and active, how much can residual skin or other bio-detritus affect the experiments, or is it a non-issue?
Oh, and don't you have the option of removing certain posts? If so, please get rid of the "Ernest Radner" posting and its replies, as they're just Crypto spam. The "report" option is totally useless. so active removal is best.
@@davidb6576 that is a great question David! I don't know the answer but I will see if SLAC scientists can shed some light!
In the video, it was said that the electron beams are diverted to different sites or equipment depending on what kind of experiment they wanted to perform, the question is won't they get more precise and efficient results if LCLS II is connected directly to all these separate experiment chambers and equipment instead of having to divert the electron beams to somewhere else if they want to do this or that. In fact, connecting LCLS II directly to all the separate experiment chambers will save time and will enable various experiments to be conducted at the same time with the same electron beams by just casting or pointing the electron beams to the separate experiment chambers if LCLS II is connected directly to all the separate experiment chambers. It will take more time and money but in my opinion, it will be a lot better.
What happens when there's an earthquake 😳🤔
do more of this
some people are on a totally different level of intelligence to design devices like this its mindblowing
great video.
Thanks!!
I don't understand anything about Particle accelerator but it's interesting.
when someone in the future watches this they will all be laughing at our chin diapers
Nice video presentation off "prospective"
All of that funding and with a flickering neon light @ 1:18 lol
i guess it isn't bothered by earth quakes (bay area has a few) and traffic vibration. i've driven over that thing thousands of time, always wondered what was going on.
4:10 The 'Gun', c'mon man... call it 'MEGATRON!' 🔫🔫🔫🔫🔫🔫🔫🔫
Yea big machine, costs lots! Science!
Everything must be precise, seems to me like it's a weapon
Watches are also precise.
You’re Absolutely Right. This Particle Accelerator Is The Source Of Silicon (Crystal Rock Encoded With Digital Data) That’s Why Silicon Valley Is Right Next Door.
dumb
Building in a very strong seismic earthquake prone state, especially with TAX dollars, with a project that needs millionths accuracy in a line, is insanity!
Somebody call Star labs I was looking for a circle shaped accelerator the flash can’t work with this
I straight up working on my car engine was complicated. But man I wouldn't even know where to start with these machines.
Agreed 😂
As a young person wanting to do stuff like this how would I get into it
Go to college for Physics and make professional networking a top priority. Build things at home, like fixing your car, or do fun computer science coding projects. Stay interested and make it a hobby so that when life gets tough the skills to be successful are an outlet for you to feel better rather than feeling like a burden. The people at LCLS are both astoundingly smart and, more importantly, some of the kindest people I've ever met.
Most impossible thing to see is that for light at impossible speed to make a 90 degree turn without handbrake or breaking is same like running a straight line... wtf....👀
I have a 7 inch particle accelerator
When ever I hear this kind of news I feel world is progressing
Me too!
Run, Barry, Run!
🤯
So the laser is going at the speed of light meaning its illuminating whats already hidden..?
We are still so un advanced. I hate it here.
Science rules!
The music is distracting and does not fit. Pity because the info is very interesting.
CERN?
Just wondering why but yeah nice.
Is Eobard Thawne and his team (Cisco Ramon and Caitlin Snow) behind this invention? If so, it's going to blow up and Flash is going to be born. O...no...So, do other metahumans too! I knew it.. 2022 will be the year of the time machine discovery!!! Yeah, baby!!!.. Sorry, too much movies while Covid lockdowns. ;-0)
I hope they didnt alow cnet to install any adware on their computers
It seems that they know what they are doing
Yup.. when only need to wait 50 years to wait a single product of them.
Niobium, Made in USA... or at least found there.
The NERD CENTER 😭
7:27 how my dad describes himself on the daily
All i can say if theres a zombie outbreak im hiding there gots to be secure i hope
👏🗿
6:57 wait. What he talkin about again? Didnt think we were talking about erections.
Stargate
Think of iron
Describing a highly Scientific invention using MILES instead of metric unit. damn.
First and cool 😎 video
They're always right on the verge of breakthrough huh? They've only needed another year and few million euros for what, over a decade now?
I drive a forklift 😪
Why couldn't you build the particle accelerator out of giant fiber optic cables, And add light.
cause its made of fibers, your way. they need metal, fibers are too weak.. its in bananas you know
@@thekodanator The magnetic field is what's containing the particles, not the metal in the walls.
This Particle Accelerator Is The Source Of Silicon (Crystal Rock Encoded With Digital Data) That’s Why Silicon Valley Is Literally Right Next Door. I’m Just The Messenger.
I wonder were they getting all the money from
Make America Great Again - this. Not chanting Let's Go Brandon like a bunch of twelve year olds.
lets go brandon
@@Grizzlyx9 Oh, a twelve year old. Run along, adults are talking.
@@davidb6576🤓
Yet Nobody at this Billion dollar facility for 30 years discovered Graphene?
11:19 Wow, I feel smarter than these two scientists for wearing face mask properly
This will further AI development and further obselencing the human the future is borg
Master baiter.
Miles? Fahrenheit? 😂
You don't need all that area for that. Your thinking is wrong
LoL
I feel aliens perfected this, using solar light to power their spaceships. We are just now touching the surface of this technology with solar panels. This is how I feel aliens can travel to different galaxies and solar systems at the speed of light… It seems to be the only logical way…
do you think aliens perfected light powered vibrators?
😯
Meanwhile, MBS spends half a Bn USD on a fake Da Vinci picture auctioned at Sotheby's...we could really use this laser to obliterate one or two dictators out of this world...😛
Hope those walls are reinforced against your average North American driver 😂
This just proves that the earth is flat and motionless, 2 mile long laser?? Where's the curvature where where???
The earth is so large that the curvacture is subtle. There is an equation to find how far you can see before the horizon is out of line of sight. R^2 + x^2 = (R+h)^2
What a time wasting machine.. its like people watch a stone drop in 30fps and this machine produce 1000fps, for what ? . The product already mass produce by the 30fps companies, meanwhile this guys still watching their photos.
Inside one of the MOST DANGEROUS and IRRESPONSIBLE devices that has EVER existed on this earth. It should not exist for a couple of nerds that want to do experiments that can endanger the earth.
I was interested till that famboy started speaking. I'm out.
I only don't understand why these people are talking and explaining things with masks on their faces. This is utterly idiotic. It spoils the whole video.
Because we trust science! Thanks for watching!
@@andyaltman5778 You guys are not vaccinated? Wow! And you said that you trust science...
@@borislavkgeorgiev Does it make you comfortable and warm to disparage research while wallowing in your ignorance? Hey, great if it does, but keep it to yourself, will you? You're an embarrassment.
@@borislavkgeorgiev time to go read up on covid, vaccines etc. hint. Fox News website won’t have anything of use.
I agree. Take off mask. Not needed.
