Since use of such deflecting structures leads to growth in vertical amplitude and slope of elec-trons, non-zero momentum compaction factor, nonlinearities and coupling of the elements be-tween the deflectors af¬fect the tilted electrons even in perfect machine and change their ampli-tude 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 de-tail analyses of effects of non-zero momentum compaction factor and sextupoles between the deflecting structures, as sources of emittance degradation in TPS and evaluate how much emit-tance growths due to the effects. We also contrast the statuses of interior sextupoles and eluci-date them
