Module of External Particle Identifier (EPI)
The EPI consisted of 4096 proportional counters 6x6 cm2, distributed in 128 layers of 32 each. It was used downstream of BEBC for the identification of fast forward secondaries by ionization measurements in the region of relativistic rise, see M. Aderholz et al., Nucl. Instr. & Methods 123 (1975...

| Sumario: | The EPI consisted of 4096 proportional counters 6x6 cm2, distributed in 128 layers of 32 each. It was used downstream of BEBC for the identification of fast forward secondaries by ionization measurements in the region of relativistic rise, see M. Aderholz et al., Nucl. Instr. & Methods 123 (1975) 237. The photo shows one double layer module of the EPI during the construction, see M. Aderholz et al., Nucl. Instr. & Methods 118 (1974) 419.
