The Cluster AgeS Experiment (CASE) is a long term project aiming at determination of accurate ages and distances of nearby globular clusters (GC) by using observations of detached eclipsing binaries. The project consists of two parts. The first part is an extensive photometric survey of about 10 Galactic GCs with the aim of identifying eclipsing binaries (EB) located near or below the main-sequence turnoff (MSTO). The survey is conducted on the 1.0-m Swope telescope at Las Campanas Observatory. The second part of the project is devoted to determination of absolute parameters (masses, radii, ages and luminosities) of selected EBs. It includes derivation of precise radial velocity curves as well as photometric follow up observations in the optical and near IR domain.
