The D0 Run II luminosity monitor

PDF Version Also Available for Download.

Description

The D0 Run II Luminosity Monitor consists of plastic scintillation detectors with fine-mesh photomultiplier readout that cover the range 2.7 < {vert_bar}{eta}{vert_bar} < 4.4 in pseudorapidity. The detector is designed to provide a precise measurement of the rate for non-diractive inelastic collisions that is used to calculate the Tevatron luminosity at D0. Excellent time-of- ight resolution allows a clean separation between beam-beam interactions and the prin- cipal background from beam halo. In addition, timing is used to measure the position of the primary interaction vertex and to detect multiple interactions. Accurate correction for multiple proton-antiproton interactions in a single beam ... continued below

The detector is designed to provide a precise measurement of the rate for non-diractive inelastic collisions that is used to calculate the Tevatron luminosity at D0. Excellent time-of- ight resolution allows a clean separation between beam-beam interactions and the prin- cipal background from beam halo. In addition, timing is used to measure the position of the primary interaction vertex and to detect multiple interactions. Accurate correction for multiple proton-antiproton interactions in a single beam crossing is essential for an accurate luminosity determination. Associated electronics provide a single- interaction trigger term for the D0 Level 1 trigger, and readout of the photomultiplier timing and pulse-height measurements.
