I was wondering how they track the particles in particle accelerators that allow them to create images like this: http://www.supraconductivite.fr/media/images/Applications/image036.jpg
He says that the path of particles is unknown. And in the double slit, the position of photons is said to not be known until they hit the screen at the back, when its wave function collapses.
My question is, how do the images we see from particle accelerators get made, then? How is the path of particles in photon detectors observed?
I searched and found this article: https://science.howstuffworks.com/how-track-particles-lhc.htm
"One of the detectors is actually called a tracking device, and it really does allow the physicists to "see" the path that the particles took after colliding. Of course, what they're seeing is graphical representation of the particle's track. As the particles move through the tracking device, electrical signals are recorded and then translated to a computer model. Calorimeter detectors also stop and absorb a particle to measure its energy, and radiation is also used to further measure its energy and mass, thus narrowing down a particular particle's identity."
I don't know if this answers the core of what I'm confused about though, which would be how these "tracking devices" work. How can you track the paths of these particles, without interfering with the particle, or destroying it? Do these particles emit an electric field as they travel, allowing their paths to be traced with "electric signals" as this article states?
Are they tracking the particles continuously throughout their path, or do they track them at intermittent points, and the images are based on interpolating the motion in between the detection points?
Or, are these images just artist illustrations, interpretations of what's going on, and they aren't actually able to track the paths of individual particles in real time as the images imply?
