Si detectors for high energy particles

When charged particles such as alpha-rays and heavy ions strike a Si detector, their energy dissipates along a linear track whose length is determined by the type and energy of the incident charged particles, and electronhole pairs are generated by means of the Coulomb interaction of a charged parti ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
