Definition and Types of Charged Particles
– A charged particle is a particle with an electric charge.
– It can be an ion, such as a molecule or atom with an electron surplus or deficit.
– Charged particles can also be electrons, protons, or other elementary particles.
– All charged particles, except antimatter, are believed to have the same charge.
– Charged particles are labeled as either positive (+) or negative (-).
– The existence of only two types of charges is known.
– The designations of positive and negative charges are arbitrary.
– There is nothing inherent to a positively charged particle that makes it positive.
– The same applies to negatively charged particles.
Charged Particles in Plasma
– A plasma is a state of matter that consists of a significant proportion of charged particles.
– It can be a collection of charged particles, atomic nuclei, and separated electrons.
– Plasmas can also be gases containing charged particles.
– Plasma has various applications in technology, such as in plasma TVs and fusion reactors.
– Understanding the behavior of charged particles in plasma is crucial for plasma physics research.
Interaction with Charged Particles
– Charged particles can interact with matter and cause ionization.
– Ionizing radiation is produced by charged particles with sufficient energy.
– Specific ionization and LET (Linear Energy Transfer) are important parameters in radiation physics.
– The Bragg Curve describes the energy deposition of charged particles in matter.
– The range of particle radiation refers to the distance it travels in a medium before losing energy.

In physics, a charged particle is a particle with an electric charge. For example, some elementary particles, like the electron or quarks are charged. Some composite particles like protons are charged particles. An ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons are also charged particles.
A plasma is a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles.
Charged particles are labeled as either positive (+) or negative (-). The designations are arbitrary. Nothing is inherent to a positively charged particle that makes it "positive", and the same goes for negatively charged particles.
