We planed an experiment to store ion beams with no momentum dispersion in an ion storage ring,namely'S-LSR',which is under construction at Institute for Chemical Research,Kyoto University.This is based on the principle that ion beams are bent by both magnetic and electric fields at the bending sections of this ring.In this principle,the magnetic fields are perpendicular to the median plane,and the electric fields are in radial direction.To prove this principle,we carried out an experiment to bend beams utilizing a single set of the bending element which is composed of one dipole magnet and one set electrodes.We also designed and manufactured a set of electrodes to make precise electric fields(deviation of the fields is requested to be less than 0.1percents).Although the trial piece of the electrode were able to make only 20percents precision of electric fields,the results of the beam experiment showed the tendency that the first term of the momentum dispersion is controlled under the condition that the stregth of the magnetic and the electric fields are appropriately set.And we observed the second term of the momentum dispersion when the first term of the momentum dispersion is canceled.
