Observation of coasting beam at the HERA Proton--Ring

TL;DR

This paper reports the detection of a coasting beam in the HERA proton storage ring, demonstrating its inherent production during machine operation, independent of target effects.

Contribution

First experimental evidence of coasting beam presence at HERA, clarifying its origin as intrinsic to the proton machine operation.

Findings

Coasting beam exists at HERA proton ring.

Coasting beam is not caused by the target.

Data confirms intrinsic production of coasting beam.

Abstract

We present data collected with the HERA-B wire target which prove the existence of coasting beam at the HERA proton storage ring. The coasting beam is inherently produced by the proton machine operation and is not dominated by target effects.
