Design of a synchrotron radiation source at Tohoku University.
The construction of a third-generation light source has been proposed at Tohoku University. The emittance is 7.3 nm rad at the nominal beam energy, 1.5 GeV. The circumference is 194 m. The ring consists of 12 double-bend achromatic cells. Ten of 12 dispersion-free long straight sections are 5 m long and will be used for insertion devices and some accelerator components. The remaining two are each 15 m long and reserved for advanced devices, such as a very long undulator or a free-electron laser. A stretcher-booster ring, which is now under commission, will be used as an injector. In total, about 50 beamlines can be constructed and ten of them will be those of insertion devices. The present status of the project is 'waiting for approval'.
