My understanding, please correct me if I am wrong, is that in the LHC proton-to-proton collision experiments it is technically not feasible to align protons directly into each other. Why is that and where can I look this up?
Rooted said:The protons are small (around 10-15m diameter) so it is nigh impossible logistically to make one proton directly hit another one. Instead they make a beam of about 1011 protons with a radius of approximately 10-6 m. When two of these beams hit each other, the chances are that some protons will collide.
Here's a good place to look for more information http://www.lhc-closer.es/php/index.php?i=1&s=3&p=9&e=0

However, maybe you were referring to a different issue.
The two colliding proton beams are also not aligned intentionally, not because of technical limitations.
This is because if they were aligned there would be collisions at many points across the beam axis (every point proton bunches cross), and there would be a "mess" Therefore, the beams have a small relative angle which makes sure they only cross at one point. Which is the collision point
The LHC (Large Hadron Collider) is a particle accelerator located at CERN in Switzerland. It is used to accelerate protons to nearly the speed of light and then collide them together to study the fundamental building blocks of matter and the laws that govern them.
The protons in the LHC are guided through a series of magnetic fields to keep them on a circular path. When the protons reach their maximum energy, they are then directed to collide with another beam of protons travelling in the opposite direction, resulting in one proton from each beam colliding with each other.
Aligning the protons one-into-one is important because it increases the chances of a high-energy collision, which can produce new particles and help scientists better understand the fundamental laws of physics. It also allows for more precise measurements and observations of particles and their interactions.
The LHC collisions are controlled and monitored by a complex system of magnets, detectors, and computer systems. The magnets are used to steer and focus the proton beams, while the detectors capture and analyze the particles produced from the collisions. The data collected is then processed and analyzed by computer systems to provide insights into the collisions.
Through LHC collisions, scientists have discovered the Higgs boson, a fundamental particle that gives mass to other particles. This discovery has helped to complete the Standard Model of particle physics and has deepened our understanding of the universe and its origins. The LHC also continues to provide insights into other mysteries of the universe, such as dark matter and antimatter.
