Bremsstrahlung Definition and 49 Threads

Hi all, I am looking for clarification on what is probably a pretty basic change of variables between a few lines in the following paper: https://journals.aps.org/prd/pdf/10.1103/PhysRevD.34.1326 Equation (9) shows the differential cross section for a Bremsstrahlung process which...

https://www.researchgate.net/figure/Bremsstrahlung-and-characteristic-radiation-spectra-are-shown-for-a-tungsten-anode-with_fig4_8365056 Fast electrons produce X-rays in the anode of an X-ray tube through two different methods. The first one is the interaction of electrons with the nuclei of...

What are the reasons X-ray vacuum tubes could not be replaced by solid state alternatives?

Hi everyone, sorry we are talking about pulsed power accelerators again. In this context, it is about the HERMES III again. According to https://apps.dtic.mil/dtic/tr/fulltext/u2/a351472.pdf HERMES III, a 16 terawatt pulsed power accelerator at Sandia National Labs, which fired electron beams...

Some people said if it is originated from electrons then it is X-ray but if it is originated from the nucleus it is Gamma ray. But people can produced X-rays and Gamma rays by Bremsstrahlung process and in Bremsstrahlung process it is resulted from decelerating or braking electrons. So, Gamma...

Non-relativistic Bremsstrahlung is discussed classically in Rybicki “Radiative Processes in Astrophysics” where Larmor’s formula is used to find the power radiated in a collision between an electron and a Coulomb field. The Fourier transform of the pulse allows for a description of the pulse in...

Summary: Can one observe visible light bremsstrahlung when an electron beam stops in a transparent medium? The theoretical form of a bremsstrahlung spectrum is flat at low photon energies. This means that even a high energy electron beam incident on matter should cause the emission of visible...

I don't know where to even begin?

If I have an electron and positron in a vacuum, initially at rest with respect to each other and in close proximity, will they produce any bremsstrahlung radiation?

Homework Statement Electrons are accelerated in a television tube through a potential difference of 8.5 kV. What is the highest frequency of the electromagnetic waves emitted when these electrons strike the screen of the tube? Homework Equations λ = c/f E (of the electron) = V*e E (of the...

Recently i watch a video about Thermal Bremsstrahlung. and i don't understand the explanation that they use a ring instead of disk in 6:02 to 7:06. (1)how did he divided the set of electrons up into in two sets of velocities that are all in the same direction and sum over all of the different...

What happens to an electron after it has undergone Bremsstrahlung and all its energy has been converted into an x-ray photon?

Hi all, In an x-ray spectrum, the curve part represents the bremsstrahlung part, and the spikes are the characteristics x-rays. Characteristic x-rays represent a discrete energy. However, in many textbooks, I noticed that the characteristic x-rays are often represented as a peak, which implies...

Hi ! I'm not sure to post my question in a good place so please move if inappropriate... I search experimental data of bremsstrahlung interaction as we can found experimental data of nuclear interaction on EXFOR. Someone know a website which provide that ? Thanks in advance !

Antennas work with variable current that leads to accelerations and deceleration ofor the electrons, the frequency of the photon or the electromagnetic radiation I want to generate depends on the change in kinetic energy of the electron E= hf= change of kinetic energy of the electron, according...

Are there strong interactional equivalents of synchrotron, bremsstrahlung and cerenkov radiation? Or for the weak/gravitational interactions? For example, will an accelerating bare quark emit gluons?

What is the function that describes the shape of this Bremsstrahlung X-ray spectrum curve? Ignore the characteristic "spikes".

Two free electrons approach each other, so they start to emit photons due to bremsstrahlung. Where does the angular momentum carried away by the emitted photons come from?

http://www.quora.com/Why-is-the-spectrum-of-Bremsstrahlung-radiation-continuous In the above link, it says that "you will count more low-energy events since they are more probable." Which must mean that at lower energy we must get more intense radiation...

This is what we have been given in class: I'm a little confused as the electron seems to emit two gamma rays? I understand that the process can't occur if there isn't interaction with a nucleus due to conservation of momentum. Please could someone confirm that the top gamma is the initial...

Hello, I have been studying XRays recently in a general science course. It's about A Level standard but I want to take my interest further. Anyway to the point. I thought I understood the release of XRays when an electron is slowed as it ploughs into a tungsten anode in an X-Ray Tube...

Hi, I am having some difficulty understanding some of the concepts in involved in Bremsstrahlung Radiation. I have recently been learning about the Rutherford scattering experiment where an alpha particle is fired towards a gold nucleus. In my book there is a fairly simple derivation of how you...

As far as I know, bremsstrahlung radiation -especially cyclotron- can be absorbed by the plasma but it escapes because it is not dense enough etc. Have researchers tried to make lithium blankets reflect those radiations and trap the radiation inside, eventually increasing the absorption rate...

Hello. I was taught that a charge which changes its velocity must radiate (at least, in classical electrodynamics). Let's consider a charged particle which decays into another charged particle (and, maybe, others neutral particles; but not photons). In this case, can we find electromagnetic...

Hello, I am reading about the bremsstrahlung phenomenon, and am having difficulty seeing how this phenomenon clashes with classical physics. Could someone possible explain the process, and why there is no classical physics description for it?

i need to calculate what percentage of the energy put into a X-ray tube will be between the minimum wavelength and the longest wavelength suitable for it's application (as to calculate how efficiently it does it's job) with only the input voltage (unless the anode material is important) the...

Hi everyone, I have a doubt which was actually raised by a recent discussion on this forum. We know that Furry's theorem says that diagrams with an odd number of photon vanish. Roughly the reason behind that is the charge conjugation symmetry, since under such operation the photon field behaves...

basically any time i have an arc, i have electrons flowing in the opposite direction to the field gradient. so when the electrons reach the other side, they will be stopped, which will then produce an EM wave. In, class, my professor drew the direction of radiation in a particular direction, but...

1. I have problems finding the truth of this statement. The statement is cited from "book". I want to draw your attention to the following words: electron is decelerated 2. Statement: "Bremsstrahlung X rays result from Coulomb interaction between the incident electron and the nuclei of the...

I'm curious about the compatibility of a whipple shield and bremsstrahlung prevention(like that provided by paraffin). Until a short time ago, I was under the impression that bremsstrahlung is only generated when a charged particle collides with a metal. This is apparently not the case. So...

Hi everybody, first I like to thank you for this nice forum :smile: I tried the search function and found no answer to my question, so here it is: How can I calculate the Bremsstrahlungs background for TEM EDX spectras (Intensity vs. Energy)? I found several formulas, for example the...

Hi, It never occurred to me before, but when you derive the spin-orbit Hamiltonian as a perturbation to the hydrogen Hamiltonian, you imagine your electron orbiting around the nucleus, and of course that's not the correct picture because of the electromagnetic radiation that leaks out. So I...

Homework Statement Why does it happen? Homework Equations The Attempt at a Solution I read that Bremsstrahlung happens because a charged particle loses kinetic energy as it swings past a nucleus, therefore a photon is released to conserve energy. However, since the electric...

For an x-ray tube at constant voltage I know that the maximum energy Bremsstrahlung x-ray that can be produced is directly related to the voltage on the tube. But what about the minimum energy? Is there a limit, or can all energies below the maximum be produced? I realize that adding a...

Would radio waves emitted by an antenna be considered Bremsstrahlung radiation caused by pushing the electrons back and forth?

Hi all How can I plot bremsstrahlung energy spectra?What is the formula for this topic? Pleas help me! thanks a lot.

Hey, My book says: When an electron strikes the target metal it is attracted by the positively charged nuclei, and hence it loses speed and hence emits a photon of X-ray. That doesn't make sense to me. We learned that in centripitel acceleration, that the speed of the object being...

Does the timescale over which a charge decelerates determine the energy and intensity of brem photons? Consider two electrons, one is decelerated over a large distance and relatively long period of time. A second electron is involved in fast scattering event and loses its energy relatively...

Can anyone give me a nice explanation of the difference between thermal and non-thermal Bremsstrahlung? Thank you!

Hello, I'm looking for any information on bremsstrahlung in a vacuum (or near vacuum). I've been trying to look for some information on google and in my school's physics library. The one book I found in the library was checked out so I couldn't actually look at it, but it looked like the book...

Hello, I am trying to understand an equation stated in the book 'Principles of Protein X-Ray Crystallography' by Jan Drenth (The exact page I am reffering to can be found here...

It is my understanding that if an electron decelerates during an encounter with a 'heavy target nucleus', the energy lost by the electron is converted to an x-ray. The book I'm using says that 'the target nucleus is so massive that the energy it acquires during the collision can safely be...

Hi! I need to know what's the "hard bremsstrahlung emission". I googled it but it only showed papers (and few because my university don't have access to many) on experiences that at some point mention this effect but don't explain it. I know what's bremsstrahlung emission, just don't know...

The monochromatic gamma rays enter a scintillator (e.g. NaI). Then I compute the deposited energy spectrum. I need a techinque of modeling of the bremsstrahlung produced by the recoil electrons without direct modeling of the electrons trajectory. What could I do?

Goodmorning, I would be interrested in experimental data regarding the Bremsstrahlung process near the quantum mechanical cutoff, possibly single events data. I thought that maybe something like a bubble chamber picture could illustrate this process. This is maybe a naïve dream but this...

Bremsstrahlung is the process in which an accelerated electron radiates and loses energy in the form of a photon(production of continuous X-rays). In photoelectric effect, an atom absorbs a photon and an electron from one of the shells is ejected. So, is it reasonable to regard X-ray...

In Chapter 6 of M. Kaku's book (QFT), he wrote (p184) "...by rotating the diagram around, we can convert bremsstrahlung into pair creation." Bremsstrahlung, as far as I know, involves atoms. Does this mean that when bremsstrahlung with >1.2 MeV strikes an atom we will get an electron and a...

Bremsstrahlung and Cerenkov I've been wondering about the different cases of light emittion, and the most unclear to me are Bremsstrahlung and chrenkoff. If u can, please give me details about these two cases. Thank You. :D

An electron which is decelerated emits a photon (Bremsstrahlung). When neutral hydrogen is formed putting together one proton and one electron (a free electron is bound by a proton), does the electron decelerate and does it emit a photon? Thanks.
