Abstract :
In order to estimate the possibility of bunch lengthening in the ATF damping ring, the longitudinal broadband impedance of the ring was evaluated. The inductance was so small, that the bunch lengthening should not be observed in the ATF damping ring. It is found that the total mod Z/sub ////n mod is less than 0.3 infinity . Therefore bunch lengthening should not be a problem in the ATF damping ring.<>
