Abstract
We describe an automated precision thickness measurement system which has been developed to control the quality of the 6160 lead plates form ing the absorbers for the ATLAS electromagnetic Lead-Liquid Argon calo rimeter. By using an ultrasound measurement technique combined with au tomated scan tables and pneumatic operation, robust, low cost, fast an d easy to operate systems have been built. The required accuracy is at the level of a few microns per measurement point, with about 500 poin ts per plate. (C) 1998 Elsevier Science B.V. All rights, reserved.
