An electrostatic particle accelerator is a type of particle accelerator that uses electric fields to accelerate charged particles, such as ions or electrons, to high velocities. Unlike other accelerators that might use magnetic fields (like synchrotrons or cyclotrons), electrostatic accelerators rely primarily on static electric fields generated by high-voltage systems.

Lin Haiqing
"Lin Haiqing" is not widely recognized in popular or academic contexts, and there may be multiple individuals or references associated with this name. It could refer to a person or a specific concept, place, or cultural reference that is not well-documented. If you have more context or specific information about Lin Haiqing, such as the field (literature, history, etc.
Free-electron laser
A Free-Electron Laser (FEL) is a type of laser that generates high-intensity, coherent electromagnetic radiation — typically in the form of laser light — using free electrons instead of bound electrons in atoms, which is the case in traditional lasers. The key features of FELs include: 1. **Free Electrons**: Instead of using electrons bound to atoms (as in conventional lasers), FELs use beams of free electrons.
Magnetic lens
A magnetic lens is an optical device that uses magnetic fields to focus charged particles, such as electrons, rather than using traditional glass lenses that refract light. These lenses are commonly used in electron microscopy and particle beam instruments. There are a couple of main types of magnetic lenses: 1. **Electromagnetic Lenses:** These lenses utilize coils of wire (electromagnets) to create a magnetic field.
Lionel Kimerling
Lionel Kimerling is a notable figure in the field of materials science and engineering, particularly recognized for his contributions to the study of semiconductor materials and nanostructures. He has been involved in research focusing on the properties and applications of various materials, including silicon and its alloys, as well as other advanced materials used in electronics and photonics.
Mean transverse energy
Mean transverse energy, often denoted as \( \langle E_T \rangle \), is a concept frequently used in high-energy physics, particularly in the analysis of particle collisions and events in collider experiments like those conducted at the Large Hadron Collider (LHC).
Microtron
The term "Microtron" can refer to different concepts, primarily in the fields of physics and technology. Here are a couple of notable references: 1. **Microtron in Particle Physics**: In the context of particle physics, a microtron is a type of particle accelerator designed to accelerate electrons or other charged particles. It typically employs a circular path and uses a combination of high-frequency electromagnetic fields to achieve acceleration.
Microwave cavity
A microwave cavity is a structure used to confine and manipulate microwave radiation, which typically operates at frequencies ranging from about 300 MHz to 300 GHz. These cavities are specifically designed to resonate at certain frequencies, allowing them to enhance the intensity of the electromagnetic fields within the cavity. Microwave cavities can take various forms, such as rectangular or cylindrical shapes, and are usually made of conductive materials that reflect microwaves effectively.
The American Physical Society (APS) Fellowship is a distinction awarded to members of the society who have made significant contributions to the field of physics. The list of APS Fellows includes names of individuals who have been recognized for their exceptional achievements, research, and service to the physics community. Being elected as a Fellow is a prestigious honor and typically involves being nominated by peers.
Particle beam
A particle beam is a stream of charged or neutral particles that are directed down a certain path, often used in various scientific and industrial applications. Particle beams can consist of different types of particles, including electrons, protons, ions, or even whole atoms. The characteristics of a particle beam can vary based on the type of particles being used and the means of acceleration and focusing.
Llewellyn Thomas
Llewellyn Thomas is a name that may refer to several different individuals, but it is often associated with Llewellyn Thomas (1914-1992), a noted British physicist who made significant contributions to the field of atomic and molecular physics. He is particularly recognized for the Thomas-Fermi model, which describes the distribution of electrons in atoms and is an essential concept in quantum mechanics.
Lou Kondic
Lou Kondic is not a widely recognized figure, concept, or term within mainstream knowledge as of my last update in October 2023. It’s possible that Lou Kondic could refer to a lesser-known individual, a fictional character, or a niche topic that has emerged after my last training data. If you can provide more context or specify the area (such as sports, literature, history, etc.
Scanning Transmission X-ray Microscopy (STXM) is an advanced imaging technique that combines the principles of scanning microscopy with X-ray transmission imaging. This approach allows for high-resolution imaging of material samples at the nanoscale, as well as the chemical and electronic characterization of those materials. ### Key Features of STXM: 1. **X-ray Source**: STXM typically uses synchrotron radiation, which provides highly collimated and intense beams of X-rays.
Storage ring
A storage ring is a type of particle accelerator that is designed to store beams of charged particles, such as electrons or protons, for extended periods of time. Unlike linear accelerators, which accelerate particles in a straight line, storage rings use bending magnets to confine particles in a circular or polygonal path, allowing them to circulate repeatedly through the accelerator.
Strong focusing
Strong focusing is a technique used in particle accelerators and certain types of beam optics, particularly in the context of magnetic fields. It refers to a method of focusing charged particle beams using specially designed magnetic fields that can maintain better control over the particle trajectories compared to traditional methods. In strong focusing, a sequence of alternating gradient (AG) magnetic fields is employed.
Lu Yu
Lu Yu (陆羽) was a notable Chinese tea master and writer from the Tang Dynasty (618–907 AD), often referred to as the "Sage of Tea" (茶圣). He is best known for his work "The Classic of Tea" (茶经), which is considered one of the first comprehensive texts on tea culture, including its cultivation, processing, and methods of preparation.
