If you are finanically independant you can seek out who you "work" with. That should be the aspiration of every scientist, your only there as everyone is nice and curious, as soon as the environment is cut throat, ruthess or toxic then you just disappear.

Honestly, her voice is gold...her jokes disarming and it makes me feel great every time I hear it.

It's fun to imagine what Meitner, Curie, Rutherford, and Thomson would have to say if they could listen to Ms Sheehy's talk.

Great talk. I really enjoyed listening to you bring back memories. You are in an exciting field with great potential for the future. Keep up with your good work! As a young engineer working in my employer's Super Power Lab my first job was to take a 10 foot section of an "S-band" linear accelerator and marry it to a high power crossed field amplifier in a single vacuum for a medical application. I went on from that application to design high power microwave tubes for military radar and industrial applications. Later I led a group for over two decades working on high power industrial microwave designs for many applications in the food, foundry, ceramics, nuclear waste remediation, medical sterilization, and even power beaming to name just a few. I hope you are still at it and wish you the very best.

In Texas, we saw the possibility of a super-duper collider become a financial fizzle. Thus life beyond the CERN is hard to shake out of the coin purses of governments. It's interesting to see that more types of useful accelerators are possible that won't consume all the money in all the nations of the world. Sheehy's talk should be required viewing for our legislators.

To me, unless you get into being lazy with social management of large populations because of the refusal to provide value added programming for mass and energy management... these particle accelerators systems seem delusional grandiose strange to invest in without more distributed, secured and I think even placed underground, underwater or on barges nuclear power plants. Seems strange the gaps in physics, engineering and actual implementations when we have more feasible implementations that can be energy efficient and even use more heat from solar not being implemented for the masses. Say for nuclear... to not waste water or to refine sea water... why aren't novel investments in desalination of sea water at nuclear power plants or even external combustion generation at nuclear power plants explored for say solar concentrating trough power stations hybrid designs where we don't require to waste water? Seem mentally ill to me some days the inconsiderate to our constituents implementations not being implemented to bring costs down for higher quality survival requirements at extreme population densities and these delusional forensically clean killing systems for grandiose, delusional, narcissists that have some insane cult mission. Maybe I am missing something to comprehend why? What are the actual milestones they are trying to determine that will aid for practical applications to the masses other than radiating people to death with systems that we know are not as effective as others that we know are?

Yeah, the camera angle made it look a lot worse than it was.

Wonderful lectures, and this is another. Informative, communicative, and welcoming to the uninitiated - at least most of them. Love it when real scientists present real science.

There are so much similarities and same mechanisms and apparatus used in both particle accelerators and mass spectrometers i use in chemical analysis.

I will freely admit that I clicked on this link because I saw a pretty lady wearing a mic. She's got a great accent and she has the crucial ability to simplify complex ideas. When she got to the part about resonance, I immediately remembered a commercial featuring Ella Fitzgerald's voice shattering a wine glass.

I like the way she shares her knowledge with the audience. She makes it look so easy.

I grew up in Burbank, Illinois, about 40 miles from Fermilab.

What a great communicator! Wish to hear more from her!

At 11minutes was at the Fermi lab awhile back. Super amazing.

This is a awesome channel and I'm very thankful they post these vids, let alone for free. It's a beautiful thing.

About the problem with charged particles interacting with each other in a particle beam and therefore pushing each other apart and defocusing the beam -- has anyone ever tried running negatively and positively charged particles or ions in the same beam in a circular accelerator? They would presumably rotate in opposite directions. Would the presence, and intermixing, of negative and positive particles in the two intersecting beams improve their focus?

17:00 - 17:09 400MHz is 400 Million oscillations per second not 400 oscillations per second. Otherwise interesting talk.

A bit of CERN HUMOR...

The analogy of the complex resonances is that your various instruments now become an orchestra and you have to figure out how to make the tubas work with the violins to make music (your desired acceleration without problems) and not noise. You need a Mozart to do this...

Susan Sheehy is further proof that STEM girls rock! We need more of them.

This kinda of knowledge just available for practically free just blows my mind!!

One of the DSLR cameras used for filming has so many dead pixels that it contaminates the image quite noticeably.

10/10 talk. You've enlightened me to the world of particle accelerators.

My responses to these videos may be late, but I feel somebody somewhere might appreciate them so here I go; Thanks for the BRILLIANT presentation. I spent a while thinking "Oh particle accelerator, I get it", but you've realy demonstrated great depth that I must have been previously missing, as that's the only way to explain the racing thoughts this video gave me. Miniature accelerators, suuuper sized orbital accelerators, from medicine to magic.

I never thought I'd see a resonance cascade.

38:30 I would bet, just based on our relative intelligence that her guess would be better than mine.

I would add statically charge energy from lambs hairs and glass rods or curved glass sheets and spacers to static ballance.

Studied about. The working applications technology and particle physics in accelerator

A truly excellent speaker and lovely manner. More women like her are needed as STEM role models for young women.

17:05 400MHz != 400x a second edit: okay, one moment later she said it correctly ^^

There is some lost energy (particles) when a beam is coaxed in more than one direction at once. Meaning in a Zed Vector? Or, are you saying the entire beam is lost if you change the algebra of the curve to bend in an additional direction?

Dr. Sheely, have you considered augmenting your Paul trap design together with the motivating force of a Cyclotron? IOW use a synchronized electric charge to attenuate the attractive (counter-containment force) of the alternating magnetic fields.

The platter used to spin the demo quadrupole trap is out of balance. The unit is beautifully built so I expect it didn't start that way. With all the smart people in the room I'm sure it can be repaired.

I understand very little about the newer generations of particles, but I'm curious if the muon is a heavier form of an electron, couldn't we use it in a fashion to transfer more electrical energy? Just a shot in the dark, if I'm misunderstanding the generational steps, please forgive me. This lecture was very interesting and fun, a spark if you will, thank you very much!

Perfect and pleasing one.....many many thanks Suize

Super interesting. I had no idea about all the current practical applications. As far as my ideas of future applications that she spoke of in her closing, I can only believe that they will be of ideas only found in science fiction at the present.

I so want to go back to school. Especially science.

At 17:04, mentioned 400 MHz saying that's 400 times per second, but should have said 400 million times per second. She corrected it at 17:20 though.

All right everything is focused on increasing specific energy of the beam but what about the application of the accelerator as propulsion a mean for lowering entropy as it's time to phase out the internal combustion engine technology old almost two centuries

What, no mention of tabletop laser accelerators? Looking forward to watching the Q&A...

Study interfering with the magnets. Get Goggles deep blue to work out how the winding of wires of brass mixed with some mercury interlineated or interlocking interlaced interphased and bolts of brass shot through the windings and lead steel wood. A wooden bolt like a telephone poll but made out of compress cedar but ONLY with the knots of the tree as the raw material and some binding agent. Also with wormy chestnut and redwood. DB will spit out like a million different ways you can bend an energy beam. Then build a a two figure 8 shaped loop that has been twisted over itself enough to stack vertically and drill giant deep bore holes around the perimeter filled with wave absorbing material that will divert waves travelling across the top of the ground into energy transferred into them to damping seismic interference. Save a 100km of digging.

Sooo... What would we need to divert asteroids using a particle cannon? Would it be easier on earth or in orbit?

Amazing lecture, I really enjoyed the theory of magnetic fields oscillating with induced electromagnetic' to give an avalanche type of effect to the particles in a cavity, If these could be strung together in such a way that increased energy is applied to the particles. Is this the idea being put forward to increase the energy output, have I understood what is being proposed.

Just wondering if a flood of electrons could be used to reduce space charge effects.

talk nerdy to me

Miss Sheehy are You for real?? All that intelligence, beauty an sympathy bundled in one individual is simply too difficult to believe… all my good will and admiration for You… Best regards!! Victor Micha Mexico City. 🇲🇽 ✌🏽😎

What a brilliant video this was. Thanks

It was a very interesting talk, but I had trouble understanding the resonance graph at 37:30 can someone break it down for me? Is she trying to show that 2.5 is the ideal value to reach for both vertical and horizontal oscillations?

The cyclotron at TRIUMF will continue to be important in the coming years due to its exceptionally bright proton beam and the ability to accelerate rare isotopes.

The moon is mostly iron right? And the center of the earth is a big iron core that rotates to help create earths magnetic field right? So instead of trying to rotate the moon to create a massive energy field why don't we build a synclatron around the moon and use the speed of the particles inside the synclatron to mimic the earth core and allow us to create a giant gravity wave projector.

Number of atoms in the human body is about 10^27. Number of stars in the observable universe is about 10^24

So why not have more accelerators in parallel, each focusing their beam to a common output?

How can someone dislike this A deep explanation

Hi, i was watching a video on lathe work, and how resonant can ruin surface finish, but constantly accelerating and de accelerating the RPM would help. That might work on the turntable model too, you mentioned experiment similar in the video but to be honest i didn't that part

Love that this starts off with New Zealand (Rutherford) :-)

I wonder what the beam cross sections / diameters are (average in storage rings, not in lenses or experiment halls) or diameters are of the 1MW class machines. Designing beam dumps for those must be fun. O_O

Is proton-beam decay acceleration necessary for nuclear waste recycling in a Thorium reactor if you use a Molten Salt Reactor (MSR)?

Can the Paul trap be compared to the conical scan radar tracker, where you use the low-power null at the exact center of the beam by cocking the power beam slightly off at an angle and rotating the antenna to make this beam rapidly go round the central axis, which can be very small, allowing very tight tracking of a target?
