Particle Accelerators: How do I calculate the amount of particles per bunch?

Click For Summary

Homework Help Overview

The discussion revolves around calculating the number of particles per bunch in a particle accelerator, specifically focusing on a collider with a circumference of 26.66 km and a collision frequency of every 22 microseconds at four points. The average current for each beam is given as 3 mA, with four bunches in each beam.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between current and the number of particles, questioning the charge of the particles involved and how it relates to the overall current to derive the rate of particles passing a point.

Discussion Status

Some participants have provided guidance on using the charge of the particles and the definition of current to approach the problem. There is an ongoing exploration of relevant equations and concepts without a clear consensus on the solution yet.

Contextual Notes

The problem context includes specific parameters such as the type of particles (electrons and positrons) and the structure of the collider, which may influence the calculations. The original poster expresses difficulty in finding a relevant equation.

Homework Statement




The circumference of the collider is 26.66 km, and there are 4 equally spaced points where the beams collide.

A collision takes place every 22microseconds at each one of the collision points, with 4 bunches in each beam.

The average current per beam is 3mA.

I have to work out how many particles per bunch this corresponds to?


I've looked everywhere for a relevant equation and can't find anything! Any ideas please?

do you know what the charge of the particles is? you're given a current...
 
Yes, sorry, they are electrons and positrons colliding.
 
ok, so if you know the charge of a particle & the overall current, you should be able to calculate the rate of particles passing a point... (from the definition of current)
