Description
Sampling calorimeter is indispensable for physics measurement at col-
lider experiment with PFA. Uncertainty of deposit energy at absorber layer
degrade energy resolution. This problem will be solved by using lead glass as
absorber, which is clear and heavy. High energy particles produce Cherenkov
lights whose light yield corresponds to the track length in the lead glass.
This information from the absorber will improve the energy resolution of
the calorimeter. Performance of this calorimeter prototype tested for elec-
trons at ELPH beam at Tohoku University will be presented. We will discuss
the problems and its capabilities.
