Abstract :
NSLS-II is a third generation light source under design. The beam stability control has been taken into consideration. In this paper we looked into the longitudinal tolerances. We found that the timing and infrared beamlines are the most susceptible to the longitudinal noise. The rest of the beamlines are affected because of the dispersion and the momentum dependent vertical divergence effects. We set a tolerance of Deltap/p <5 x 10-5 on the longitudinal energy oscillation amplitude.
