Abstract:
A prototype liquid argon preshower detector with a strip granularity of 2.5 mm has been tested at the CERN SPS in front of a liquid argon Accordion calorimeter. For charged tracks a signal-to-noise ratio of 9.4 and a space resolution of 340 mum were measured; the rejection power against overlapping photons produced in the decay of 50 GeV pi0's is larger than 3; the precision on the electromagnetic shower direction, determined together with the calorimeter, is better than 7 mrad above 40 GeV; the calorimeter performance behind the preshower (approximately 4X0) is fully preserved. These results make such a detector attractive for future operation at the CERN Large Hadron Collider.
