Experimentally how do we make sure that the ejected electrons are coherent?

The double slit experiment is a famous physics experiment in which a beam of particles or waves is passed through two parallel slits and the resulting interference pattern is observed on a screen. It is used to study the wave-particle duality of matter and the principles of quantum mechanics.
In the double slit experiment, coherent electrons refer to particles that have the same energy, momentum, and phase. This is important because it allows for the observation of interference patterns, which are a result of the wave-like behavior of these particles. Incoherent electrons, on the other hand, do not produce interference patterns and are used as a control in the experiment.
Coherent electrons exhibit wave-like behavior, meaning they can interfere with each other and create an interference pattern on the screen. Incoherent electrons, on the other hand, do not exhibit this behavior and instead create a simple pattern of two separate lines on the screen.
The coherence of electrons can be affected by a number of factors, including the distance between the two slits, the size of the slits, and the energy of the electrons. These factors can alter the phase and momentum of the electrons, which can result in changes to the interference pattern observed on the screen.
The double slit experiment is a fundamental demonstration of the wave-particle duality of matter. It illustrates that particles can exhibit both wave-like and particle-like behavior, depending on how they are observed. This has significant implications for our understanding of quantum mechanics and the behavior of matter on a microscopic level.
