	We have demonstrated the idea of circulating a short, intense linac bunch for some tens of turns in an isochronous ring. We compressed a bunch from the SPring-8 linac to a few picoseconds rms by means of an energy compression system and a beam transport line from the linac to NewSUBARU. The NewSUBARU storage ring was set to a quasi-isochronous condition and the bunch circulated for some tens of turns after injection while maintaining the short bunch length. And we measured the coherents synchrotron radiation at 90-140GHz by semiconducter detector. The bunch length is maintained in about 20 microseconds, but the CSR power decreases little by little.
