Abstract
Trapped protons are responsible for the main component of LEGRIbackground. Detailed theoretical model has demonstrated that theproton-induced counting rate is two orders of magnitude larger thanthe counting rate of the diffuse gamma-ray flux. The continuous passesof LEGRI through the SAA (7 times everyday) makes very difficult thebackground modelling. Long and short lived isotopes contribute in verydifferent time scales to the proton-induced background component.The goal of this paper is to present a comparison between the long-livedbackground noise theoretical predictions and the experimental data. Theresults show an unexpected good agreement between the predicted and theobserved counting rates.
