Corbett, W. J.

SPEAR will soon operate as a dedicated synchrotron radiation source with up to 5 beamlines fed from insertion devices. These magnets introduce additional focusing forces into the storage ring lattice which increase the vertical betatron tune and modulate the beam envelope in the vertical plane. The lattice simulation code GEMINI' is used to evaluate the tune shifts and estimate the degree of betatron modulation as each magnetic insertion device is brought up to full power. A program is recommended to correct the tunes with the FODO cell quadrupoles. 4 refs., 8 figs., 1 tab.
