Corrector Power Supplies with a DAC Resolution up to 24 Bits based on 16 Bit DAC Devices

Abstract

At BESSY the standard 16 bit resolution of the corrector power supplies was insufficient for the continous orbit drift correction. A new sophisticated design of the analog/digital I/O board increases the resolution of the analog output up to 24 bits without suffering on losses in the long term stability or the dynamic range of the correctors. This is achieved by a cost-efficient boarddesign using standard 16 bit DAC devices in an range-overlapping fine/coarse architecture.
