Abstract :
The Higher Order Modes (HOM) spectrum of the first RF cavity of the ANKA storage ring has been fully characterised. Possible beam-cavity interactions leading to unstable longitudinal and transverse coupled bunch oscillations have been then analysed as a function of the cavity temperatures. Proper temperature settings are computed in view of the commissioning start of ANKA, scheduled for the end of 1999
