Electromagnetic Adventures #1: How to steer a proton

In the LHC, there are 1232 components responsible for deflecting the protons, but only 8 responsible for accelerating them. Why is there such a big difference? What do we even mean by deflection and acceleration? This #TeachingTuesday video is the first chapter of our Electromagnetic Adventures miniseries. We’ll talk about electromagnetic fields, how to control a beam of electrically charged particles and how to design a particle accelerator like the LHC. Find the interactive version of this video over on our website: cern.ch/proton
As part of the education portfolio of #CERNScienceGateway, the #CERNSolvayEducation programme was launched by CERN jointly with ‪@SolvayGroup‬ for the #STEMeducation of high-schoolers. It is designed for teenagers who want to go beyond high-school physics and get an introduction to CERN #physics and #technology. In each video, you can test your understanding by answering quiz questions. If you are at least 16 years old, you can enrol for free in the online CERN-Solvay Education Programme towards obtaining a digital certificate, which will allow you to apply for a CERN-Solvay residential student camp.

Ok, so I hope the videos go into how the individual packets or groups of protons get loaded into the main ring. Is the main ring first loaded full of groups at the same energy and then the main ring accelerates all of these packets simultaneously or are new groups being introduced continuously from the injection ring/s? How does the geometry of the radio frequency cavities deal with the different energy / velocities of the groups of protons? How much of the input acceleration is used to deal with synchrotron radiation losses? Are the packets periodically dumped to allow a fresh set of packets to be introduced to deal with defocusing and other issues or has a steady state mode that is in equilibrium for a relatively long time. Second OK, now that I know that there are 8 straight sections and that there are radio frequency cavities the googling was easy. The LHC’s RF cavities bring the 450 GeV energy of the particles (1 GeV = 1 billion electronvolts) to 6.5 TeV (1 TeV = 1 million million electronvolts) - more than 14 times their injection energy. The maximum energy is reached in around 20 minutes with the bunches having passed through the RF cavities more than 10 million times. The field in an RF cavity is made to oscillate (switch direction) at a given frequency, so timing the arrival of particles is important. In the LHC, each RF cavity is tuned to oscillate at 400 MHz. When the beam has reached the required energy, an ideally timed proton with exactly the right energy will not be accelerated. By contrast, protons with slightly different energies arriving earlier or later will be accelerated or decelerated so that they stay close to the desired energy. In this way, the particle beam is sorted into packs of protons called "bunches". That is fascinating!

I think Dark matter is nothing but frozen time in another dimension Dark matter melts into time and expands the space of Universe, it bends light at denser points, yet only detectable by its effect on observer and is always untouchable and unfathomable like time. When velocity of an object increases, dark matter acts thicker on it like ice, rather than liquid, and melts slowly. When velocity is less, it melts faster into time. So time wears out quickly the slower moving objects like us (And it wears out the micro world organisms like bacterias even faster, unless they have defense mechanisms against it). Thats the time dilation in relativity Just like when a spacecraft re-enters earths atmosphere, it feels air thicker than it normally does at lower speeds A wormhole is the absence of dark matter due to excessive melting and it consumes lots of energy to maintain it. Dark matter touches almost everything observable, hence information is passed on between entangled particles Dark matter limits the speed of light. Speeds higher than C is also possible in the absence of Dark matter (Eg. inside Wormhole) Gravity thickens Dark Matter. It melts slowly near the source of gravity and melts faster into time when away from the source of gravity Dark matter exists even before Big Bang and acts as a controlling canvas for Big Bang. And the Big Bang is currently spreading on it

She speaks very simple english even a B2 level and not a scentific specialist like me understand every single word and meaning. If she was a native speaker she would use words from the street with some bad jokes. Thank you.
