| Title | EFFECT OF DURATION OF 120 ¿C BAKING ON THE PERFORMANCE OF SUPERCONDUCTING RADIO FREQUENCY NIOBIUM CAVITIES | ||||
| Abstract | Over the last decade much attention was given in increasing the quality factor of superconducting radio frequency cavities by impurity doping. Prior to the era of doping, the final cavity processing technique to achieve the high accelerating gradient includes the in-situ low temperature baking of SRF cavities at temperature 120 C for several hours.Here, we present the results of a series of measurements on 1.3 GHz TESLA shape single-cell cavities with successive low temperature baking at 120 C up to 96 hours. The experimental data were analyzed with available theory of superconductivity to elucidate the effect of the duration of low temperature baking on the superconducting properties of cavity materials as well as the rf performance. In addition, the rf loss related to the trapping of residual magnetic field refereed as flux trapping sensitivity was measured with respect to the duration of 120 C bake. | ||||
