A neutron source is a device or material that produces neutrons, which are neutrally charged subatomic particles found in atomic nuclei. Neutrons are used in a variety of applications, including scientific research, medical treatments, and industrial processes. Neutron sources can be classified into several types based on their mechanism of neutron production: 1. **Radioactive Isotope Sources**: Certain isotopes emit neutrons as a result of radioactive decay.
A nuclear fusion-fission hybrid is a type of nuclear reactor design that combines elements of both nuclear fusion and nuclear fission processes to generate energy. The concept seeks to harness the advantages of both methods to create a more efficient and potentially safer form of energy production.
A nuclear pumped laser (NPL) is a type of laser that utilizes the energy released from a nuclear reaction to pump the laser medium, thereby generating coherent light. This innovative technology harnesses the high-energy gamma radiation emitted from radioactive materials, typically from a nuclear reaction, to excite the atoms or molecules in the laser medium. ### Basic Principles: 1. **Pumping Mechanism**: In traditional lasers, electrical or optical energy is used to excite the atoms in the gain medium.
A Peaceful Nuclear Explosion (PNE) refers to the detonation of a nuclear device for non-military purposes, specifically for promoting civilian benefits such as large-scale construction projects, geological exploration, or resource extraction. The concept was explored during the Cold War as a way to utilize nuclear technology in beneficial ways while demonstrating the capabilities of nuclear weapons.
A "remote manipulator" refers to a device or system that allows a user to control a robotic arm or similar apparatus from a distance. These manipulators are designed to perform tasks that may be too dangerous, difficult, or impractical for a human to do directly. Remote manipulators are commonly used in various fields, including: 1. **Space Exploration**: Remote manipulators are frequently used on spacecraft and space stations (e.g.
An antineutron is the antimatter counterpart of a neutron. Just like a neutron, which is a neutral baryon consisting of three quarks (two down quarks and one up quark), an antineutron is made up of three antiquarks: two anti-down quarks and one anti-up quark. Antineutrons have the same mass as neutrons but carry opposite quantum numbers.
A cloud chamber is a particle detector that allows scientists to visualize the paths of charged particles, such as electrons or alpha particles, as they traverse a supersaturated vapor of a suitable working fluid (often alcohol or water vapor). Here's how it works: 1. **Supersaturation**: The chamber is filled with vapor and cooled to create a state where the vapor is supersaturated.
A decay chain, also known as a radioactive decay series, refers to a sequence of radioactive decays in which a parent nuclide decays into one or more daughter nuclides. This process continues until a stable nuclide is formed. Each step in the decay chain involves the transformation of one radioactive isotope into another, which may also be radioactive, until all unstable isotopes have decayed into stable ones.
The Journal of Radiation Research is a peer-reviewed scientific journal that focuses on research related to the effects of ionizing and non-ionizing radiation, including studies on radiation biology, radiation physics, and radiation oncology. The journal typically publishes original research articles, review papers, and technical notes that contribute to the understanding of radiation's effects on biological systems and the development of therapeutic approaches in clinical settings.
The Journal of Radiological Protection is a scientific journal that focuses on the field of radiological protection and the associated disciplines. It publishes research articles, reviews, and discussions on topics related to the safe use of radiation, including the protection of people and the environment from the harmful effects of ionizing and non-ionizing radiation. The journal covers various aspects of radiological protection, such as radiation risk assessment, regulatory issues, safety protocols, and advancements in radiation measurement and monitoring technologies.
The National Council on Radiation Protection and Measurements (NCRP) is a nonprofit organization in the United States. Founded in 1929, its primary mission is to provide guidance and recommendations on radiation protection and measurement to ensure the safety and health of individuals and the environment from the harmful effects of ionizing radiation.
A survey meter is a portable radiation detection instrument used to measure the intensity of ionizing radiation in the environment. It is commonly used in various fields such as nuclear energy, medical applications, environmental monitoring, and emergency response to assess radiation levels and ensure safety.
A thyroid blocker, also known as a thyroid antagonist or antithyroid medication, refers to a type of drug used to inhibit the production or action of thyroid hormones. These medications are primarily used in the treatment of hyperthyroidism, a condition where the thyroid gland produces excessive amounts of thyroid hormones, leading to symptoms like rapid heart rate, weight loss, anxiety, and heat intolerance.
William Herbert Rollins was a prominent figure in the field of radiology and is best known for his contributions to the medical use of X-rays. He was born in 1869 and became influential in the early 20th century as a physician and radiologist. Rollins played a key role in advocating for radiation safety and was concerned about the harmful effects of X-rays on patients and medical professionals.
An electric arc is a luminous electrical discharge that occurs when current flows through a gas, such as air, between two electrodes. This process typically happens when the potential difference (voltage) between the electrodes is high enough to ionize the gas, which allows electrical conduction. The arc produces a bright light and significant heat, making it useful for various applications, including welding, lighting, and electrical discharges in circuits.
General Fusion is a Canadian company focused on developing fusion energy technology as a viable and sustainable source of power. Founded in 2002 and based in Burnaby, British Columbia, the company aims to create a practical and commercial approach to nuclear fusion, which is the process that powers the sun and stars. General Fusion's approach involves using a unique technology called magnetized target fusion (MTF). This method combines aspects of both magnetic confinement fusion and inertial confinement fusion.
A plasma railgun is a type of electromagnetic weapon that uses magnetic fields to accelerate plasma (ionized gas) to high velocities, projectiles, or both. The basic principle of a railgun relies on the Lorentz force, which acts on a charged particle in a magnetic field when an electric current passes through two parallel rails.
KMS Fusion typically refers to a cloud-based solution provided by KMS Technology that focuses on helping organizations build and manage their development and deployment processes more effectively. It integrates various technologies and practices to streamline workflows, improve collaboration, and enhance software delivery.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
