Abstract :
Frequency spectra of the fields induced by beam in four superconducting accelerating cavities of CESR collider are measured and analyzed. Resonance frequencies and Q values of cavity higher order modes are extracted from these measurements. Most of higher order modes have Q values less than 2000. However, few of them have higher Q. The results are compared with computer calculations of higher order modes
