TUPWO011 | Invariant Criterion for the Design of Multiple Beam Profile Emittance and Twiss Parameters Measurement Sections | 1901 |
|
||
By studying errors in the reconstructed beam parameters as functions of the errors in the beam size measurements, we introduce an optimality criteria which can be used for the design and comparison of multiple beam profile emittance and Twiss parameters measurement sections and which is independent from the position of the reconstruction point. | ||
TUPWO012 | Relations Between Projected Emittances and Eigenemittances | 1904 |
|
||
We give necessary and sufficient conditions which two sets of positive real numbers must satisfy in order to be realizable as eigenemittances and projected emittances of a beam matrix. The information provided by these conditions sets limits on what one can to achieve when designing a beam line to perform advanced emittance manipulations (for example, round-to-flat beam transformations). | ||
