Analysis of Emittance Growth of Lattice With Transverse and Longitude Coupling

The emittance growing problem of non-corelating and non-coupling beam after passing through a lattice with transverse and longitude coupling was studied using linear transport theory. The results show that the beam effective emittance grows remarkably with the variation of initial conditions of beam after passing through the lattice. The related relations of the beam effective emittance growth and beam phase ellipse equations are given.
