HI thanks for the reply. Actually I guess I didn't clarify the situation to completeness.
The photon is actually emitted from the electron. The electron is considered ultrarelativistic so the change in momentum can be considered opposite of the electrons original momentum vector. Hence, my...
So I wanted to get some second opinions on this situation I have thinking about.Lets say an electron enters, normally, a section of bfield that is perpendicular to its motion such that the electron will undergo circular motion. This is the simple part and is labeled as "E0" in the picture...
Hi guys, thanks for the advice/response.
Yes, I can imagine that is a very complicated physics involved. I tried looking it up on google and it was pretty unsuccessful. Do you guys have anything you an refer (no matter how complex)?
I am trying to develope a simple understanding for this...
I am looking into some new physics and had the following question come up:
You have a neutral gas of let's say, CO atoms at 1 nanoTorr. An electron(s) comes passing through the gas ionizing only 1% of the gas atoms. How long does it take for the gas to come back to neutrality? In other words...
Hi All,
I am trying to understand the some of the properties of wakefields, namely the energy change. So, as a preface I am interested in primarily the wakefield due to electron beams as they progress through a curved section (the eletcrons radiate strongly when they are in circular motion)...
If we are imaging light in the far field region. We have three situations/relations (illustrated below):
Arc Length: We know the distance subtended (S) by the light ray in a lens-less system will be proportional to R (distance to the screen) and theta; simple, especially if theta is very...
Ok, so firstly thanks so much for your help...I will def look into that book because this is something that seems simple but has been giving me some trouble.
Secondly I have wrote down the solution (ATTACHED PDF) that one of the guys in my group gave me. But to be honest I don't understand...
Hmmmm, not so much. I have read quite a bit of literature but I am really perplexed because the ccd imaging the Fourier plane has a spatial dimension aspect; the pixel size.
Also the frequency domain should span an infinite plane.
I am just pretty confused. :/
Wait where the relation? The equals sign?
It does help though! Can you direct me to where I can find that relation?
Or where I can find a explanation for it. Its not a homework problem (i just made the pdf to make things easier rather than try to explain everything in words); it is part of...
Checked around a buch and could not find any help. But I needed help with:
Understanding that if I get the Inverse FT of K-space data, what is the scaling on the X-space (object space) resultant image/data i.e. for every tick on the axis, how do I know the spatial length?
More detailed...
Hmmm, this is great thanks so much. Its starting to all piece to together now. One quick question:
-If I had a two lens system of focal length f1 (front) and f2 (back), how should/would I position them to focus at infinity (assuming the observer is at a fixed position behind the back lens...
Well, resolution is not the main issue right now, I guess wrapping my head around the optics is more so.
Basically, I need to find the focal length for an insertable/removable lens (constrained to the right 150mm from the object), inserted between the object and the telecentric lens (the...
