What is the charge of the particle being accelerated in a mass spectrometer?

Click For Summary
SUMMARY

The charge of a proton being accelerated in a mass spectrometer is definitively +1.602 x 10-19 Coulombs. This value is essential for calculating the voltage required to accelerate the proton to a specific kinetic energy (KE) using the formula U = qV, where U represents the kinetic energy, q is the charge of the proton, and V is the voltage. The discussion clarifies that the charge in this context refers specifically to the proton, not the electron in the circuit powering the electric field.

PREREQUISITES
  • Understanding of kinetic energy (KE) in physics
  • Familiarity with the formula U = qV

Given: A proton is accelerated up to KE before it exits into a magnetic field and is deflected.

Question: What voltage battery is required accelerate the proton to that energy?

So I use U = qV

the question is.. what is Q.. is q the charge of the proton being accelerated through the electric field, or is q the charge of the electron that is traveling through the circuit to power the electric field?

Thanks
