Abstract :
Current dependences of the bunch length have been measured in HiSOR electron storage ring at the beam energies of 150 and 700 MeV. Significant bunch lengthening is not seen at 700 MeV for the single and opposite 2-bunch operations, while the bunch is lengthened above a threshold for the full-bunch operation. Large bunch lengthening is observed at 150 MeV even for the single-bunch operation. Such bunch lengthening is regarded to be caused by the coupled-bunch instabilities.
