What point on the spring or different masses should be the place to measure the displacement of the spring? For instance, should you measure to the bottom of the hanging masses?

Let's assume that the brightness of a field-emission electron gun is given by β = 4iB π² d²α² a) Assuming a gun brightness of 5x108 A/(cm²sr), if we want to have an electron beam with a semi-convergence angle of 5 milliradian and a probe current of 1 nA, What will be the effective source size? (5 points) b) For the same electron gun, plot the dependence of the probe current on the parameter (dpa) for α = 2, 5, and 10 milliradian, respectively. Hint: use nm as the unit for the electron probe size and display the three plots on the same graph. (10 points)
