A measurement of σtot (γp) at S = 210 GeV
Physics Letters B 293:3-4 (1992) 465-477
Abstract:
The total photoproduction cross section is determined from a measurement of electroproduction with the ZEUS detector at HERA. The Q2 values of the virtual photons are in the range 10-71ST AND 2ND LEVEL TRIGGERS FOR THE SDC SILICON TRACKING DETECTOR

Abstract:
Some preliminary design ideas for contributions to the first and second level trigger from the inner silicon tracker of SDC experiment at the Superconducting Super Collider (SSC) are outlined. At the first level it is possible to design a trigger which can recognise isolated tracks, measure their momentum and link these tracks to energy deposits in the electromagnetic calorimeter. This could therefore form a powerful isolated lepton trigger. At the second level we describe ideas for a general purpose trigger which is capable of recognising high transverse momentum tracks in both the barrel and end-cap. By means of a two-stage analysis it is possible to measure track momentum with the full precision of the silicon tracker. © 1992.THE DESIGN, STATUS AND PERFORMANCE OF THE ZEUS CENTRAL TRACKING DETECTOR ELECTRONICS
