| + | - Lubomir answered Eugene's question about the tests with spare package in the tagger. The chamber sees high rates from: 1)background photons over the whole sensitive area and 2) electrons from the radiator in the shear plane of the magnet of the order of 100kHz per wire. Electrons, unlike photons, make hits in the two chambers of the spare package. | ||
