Description

Experiment S-133 on board the ESRO satellite TD-1 has observed the sky for high-energy (>=30 MeV) gamma rays for a total period of about one year. To date, 30-40% of the data have been analyzed and they have begun to reveal the gamma-ray emission features of our Galaxy. In the course of this analysis, several problems connected with the background and the automatic scanning and processing of data telemetred from the spark chamber had to be overcome. Some of the experience solving the problems encountered in spark-chamber gamma-ray telescopes are briefly discussed

Abstract (French)

L'experience S-133 a bord du satellite ESRO TD1 a permis d'observer le ciel pour des rayonnements γ de haute energie (>=30 MeV) pendant environ une annee. Jusqu'a present 30 a 40% des donnees ont ete analysees et ont revele les caracteristiques de l'emission de rayonnement γ de votre galaxie. Plusieurs problemes lies au bruit de fond, au balayage automatique et au traitement des donnees envoyees par telemetre a partir de la chambre a etincelles ont du etre resolus pendant cette etude. On discute l'experience acquise lors de la resolution des problemes lies aux telescopes gamma a chambre a etincelles
