Abstract
A novel technique for longitudinal segmentation of shashlik calorimeters ha s been tested in the CERN West Area beam facility. A 25 tower very fine sam plings e.m. calorimeter has been built with vacuum photodiodes inserted in the first ii radiation lengths to sample the initial development of the sho wer. Results concerning energy resolution, impact point reconstruction and e/pi separation are reported. (C) 1999 Elsevier Science B.V. All rights res erved.
