It's an inside joke. TVTropes is a website that is highly addictive (even more so than these RI videos) and whenever someone posts a link to a TVT article it's common to reply with something along the lines of 'there goes the rest of my day' or the like.

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?

@NathanOkun 5 жыл бұрын

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?

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?
