Abstract:
=========
We present the current design of the interaction region for the superconducting
linear collider project TESLA. We describe the layout of magnets, separators
and collimators which are needed to accommodate a small vertex detector radius
in the large aperture appropriate for the head-on collision scheme of TESLA.
We then describe the feedback system which will be used to vertically stabilize
the beam collisions on a bunch-to-bunch basis down to a fraction of the beam
spot size of 5nm. We finally review the various background levels in the
detector region, with special attention to the impact of e+ e- pair and
secondary neutron production on the design of the TESLA detector.
