The DELPHI testbeam measurements

As a part of the upgrade of DELPHI for high luminosity running and for the high energy phase of LEP, the collaboration decided to build a new luminosity detector. This electromagnetic calorimeter, which was called STIC, was installed in 1994 after an extensive test beam program in order to study and calibrate the detector. Under my leadership our group at the University of Lund built a platform with accompanying electronics with which the calorimeters could be placed in the testable with high accuracy (better than 10 microns). This platform is one of the largest instruments ever built by the workshop in Lund.
