Abstract:

The Tracking Detector time resolution of 2ns and the 96ns periodic interaction of protons and electrons of the HERA collider require real time data acquisition at 104MHz controlled reliably to tight tolerances. Maximum event readout efficiency, fast monitoring of run time errors and testability of front end electronics require pipelining, speed and flexibility. Such an electronic Timing and control system (TCS) is operational within three main inner detectors of the ZEUS detector and is presented in this paper.

Abstract:

This paper presents our first measurement of the F2 structure function in neutral-current, deep inelastic scattering using the ZEUS detector at HERA, the ep colliding beam facility at DESY. The data correspond to an integrated luminosity of 24.7 nb-1. Results are presented for data in range of Q2 from 10 GeV2 to 4700 GeV2 and Bjorken x down to 3.0 × 10-4. The F2 structure function increases rapidly as x decreases. © 1993.
