Practical cylindrical mirror analyzer (CMA)
A practical cylindrical mirror analyzer is simulated with apertures for the beam in the inner cylinder. The presence of the apertures profoundly changes the properties of the analyzer.
It can be seen that the performance is poor. The presence of the apertures has profoundly altered the properties of the analyzer. As explained by L Frank, J. Phys. E (Sci. Instr.) 9, 670-672 (1976), the holes create diverging lenses.
