Electron beam Definition and 57 Threads

Homework Statement The original direction of the electron beam as it enters the magnetic field is along the earth’s magnetic field. If the magnitude of the earth’s magnetic field is 0.1 mT and the magnetic field due to the Helmholtz coils is 1.0 mT (perpendicular to the electron beam), the...

The problem asks me to determine the rate of breakdown due to firing 120 kev Electrons at Titanium of arbitrary thickness. I could solve this problem if I knew The average energy deposited per electron, or the Energy efficiency of the entire beam through the titanium. Given: Electron Flux...

This is my first post here so hello to anybody who reads this! I just finished calculus based physics II this semester and there are a few things I want to design and make for myself to help better my understanding of what I learned in physics. One is device I have seen that generates an...

Homework Statement Electrons which have been accelerated from rest through a potential of 500 V pass between two parallel plates that are 6.0 cm long and 2.0 cm apart, with a potential of 150 V between them. The screen is 20 cm beyond the end of the charged plates. What is the size of the...

What is the average distance between electrons in an electron beam such as produced in a cathode ray tube as they pass through the slit and then as they pass through the charged horizontal plates and magnetic coils etc that produce the deflection?

A magnetic field deflects an electron beam, but it can not do any work on the beam. Why? :confused:

I have a few problems that I'm not sure how to do (not sure what equations to use), can anyone help me? 1) At a certain location, the horizontal component of the Earth's magnetic field is 2.3 x 10^-5 T, due north. A proton moves eastward with just the right speed, so the magnetic force on it...
