A conceptual design of 3 GeV accelerator complex for synchrotron radiation facility in Tohoku area, Japan (SLiT-J) is described. The complex is consisted with a 3 GeV low emittance storage ring and a C-band full-energy injector linac. Circumference of the ring should not be exceeded 300 m because of compactness (saving cost and power consumption). Nevertheless target emittance of the ring is less than 2 nmrad, which will be really competitive with newly constructed 3rd generation light sources. Tentatively designed lattice offers a low emittance of 1.8 nmrad with reasonably wide dynamic aperture. Presuming 4 typical undulators to cover the wide spectral range such as 10 eV to 20keV, the brightness is expected from 1017-1021 phs/mm 2/mrad2/s/0.1%b.w./300mA. For the hard X-ray region, considerable photon flux may be provided by using multipole mini-wiggler with high magnetic field, which is inserted into the middle of cell. Though realistic prospect of the project is not predictable at present, we anticipate that the facility will be open in 2016.
