HI, Richard,

What is the difference between the red and blue curves? Thanks!

Hello all,

In working out the current momentum acceptance of the microscope, it occurred to me that others might also find it useful to have the following figure available. It shows the acceptance of the tagger microscope as a function of its position along the focal plane at any position that is permitted by the tagger geometry. If you have questions regarding its meaning, please get back to me. I am posting this on the wiki because I think it will be useful for groups thinking about experiments at other energies.
