Abstract
A significant increase in luminosity can be achieved at DORIS by installing additional quadrupoles in the two experimental regions 1.2 m away from the interaction points. At one interaction point these quadrupoles will be mounted in the yoke of the magnetic detector ARGUS. In order to shield the quads from the detector field of.8 Tesla two types of compensating coils will be installed inside the detector. With these “mini-beta-quads” it is possible to reduce the beta functions at the interaction points toβ =.4 m and β*z =.03 m. The expected luminosity at 5 ǦeV with maximum currents of 2 × 35 mA is L = 1.0 × 1031 cm−2 sec−1.
