Abstract:  
Since use of such deflecting structures leads to growth in vertical amplitude and slope of electrons, nonzero momentum compaction factor, nonlinearities and coupling of the elements between the deflectors afÂ¬fect the tilted electrons even in perfect machine and change their amplitude and slope at second deflecting cavity. It causes the second deflector cannot cancel the first kick perfectly and leads to increase of transverse emittance. We have studied simulation and detail analyses of effects of nonzero momentum compaction factor and sextupoles between the deflecting structures, as sources of emittance degradation in TPS and evaluate how much emittance growths due to the effects. We also contrast the statuses of interior sextupoles and elucidate them
