    Stopping Power Calculator: Calculate Energy Loss per Distance

    Created by Md jony islam

    charged particle energy loss tool

    To evaluate the stopping power (dE/dx) of charged particles when moving through material. Applicable in nuclear, particle, and radiation physics. A stopping power calculator is a calculator to determine the loss of energy per unit path length of a charged particle moving through a material. In nuclear, medical, and radiation physics, it is important to determine the interaction of particles and their depth of penetration.

    What do you need to know to calculate Stopping Power?

    The stopping power calculator assists in calculating how fast a charged particle would lose its kinetic energy as the particle passes through a particular material. This energy dissipation is referred to as stopping power, and it is usually measured in MeV cm 2 /g or MeV /cm. It is highly important to the study of the interactions between particles in applications such as radiation shielding, particle detectors, nuclear medicine, and space physics.

    The tool is able to estimate stopping power depending on the energy of particles, their charge, as well as the velocity of particles and the media they pass through. Professional applications usually make use of advanced models like the Bethe-Bloch equation.

    Frequently Asked Questions - Stopping power Conversion FAQs:

    What does stopping power measure in physics?

    Stopping Power determines the amount of energy a particle loses moving through any material. It describes how well a medium decelerates or absorbs kinetic energy from moving charged particles; thus, it is enabled to predict the radiation effects, ionization, and shielding requirements.

    How is stopping power measured in labs?

    Stopping power is given by the amount of energy that is lost when a beam of given energy enters material (electrons or protons preferentially) and its energy is monitored as a function of the thickness of the target (i.e., the target is decreased in thickness by thickness). Since energy detectors and accurate path measurement are available, calculations of dE/dx are possible, which are often confirmed with simulation tools like SRIM.

    What is electron stopping power?

    Electron stopping power is defined as the loss of energy in the form proportional to the distance moved by the electron in a medium. Since electrons have a small mass, they suffer more scattering, and their stopping power includes both collisional and radiative losses, which are especially significant in high-Z materials.

    How to calculate electron stopping power?

    To calculate electron stopping power, use empirical models (Bethe’s equation) or simulation tools that take energy, the material density, and the atomic number as input. At low energy, collisional losses predominate and increase at higher energy, particularly in dense or high-Z material.

    What affects the stopping power of a material?

    Stopping power is dependent on the atomic number (Z) of the material, electron density, and density (ρ). Greater Z values and higher density materials result in greater ionization/compton scattering regardless of density and hence higher energy loss per path length and thus, the stopping power for charged particles, such as alpha particles or electrons depend on the stopping power depends on Z and density, higher Z and denser the material more is ionization or energy loss per unit path length, hence higher stopping power.
