Abstract
A prototype of the extreme forward calorimeter (EFC) for the BELLE detector has been tested at the KEK-PS π2 beam line by using beams with energy from 1 to 3 GeV. Prototype EFC consists of 20 radiation hard BGO crystals in a 4×5 matrix arrangement, corresponding to 18 of its full scale at the backward side. Due to space limitations, it has only 12 radiation lengths. The measured energy resolution is about 7–10% with linearity ∼1%.
