Test beam results for a shashlik calorimeter with longitudinal segmentation

Mostrar otras versiones (1)

A novel technique for longitudinal segmentation of shashlik calorimeters has been tested in the CERN West area beam facility. A 25 tower e.m. calorimeter has been built with vacuum photodiodes inserted in the first 8 radiation lengths to sample the initial development of the shower. Performance in t...

Descripción
Sumario:A novel technique for longitudinal segmentation of shashlik calorimeters has been tested in the CERN West area beam facility. A 25 tower e.m. calorimeter has been built with vacuum photodiodes inserted in the first 8 radiation lengths to sample the initial development of the shower. Performance in terms of energy resolution, impact point reconstruction and e/ pi separation are reported. (11 refs).
