Space engineering - Multipactor, design and test
This standard defines the requirements and recommendations for the design and test of RF components and equipment to achieve acceptable performance with respect to multipactor-free operation in service in space. The standard includes:
- verification planning requirements,
- definition of a route to conform to the requirements,
- design and test margin requirements,
- design and test requirements, and
- informative annexes that provide guidelines on the design and test processes.
This standard is intended to result in the effective design and verification of the multipactor performance of the equipment and consequently in a high confidence in achieving successful product operation.
This standard covers multipactor events occurring in all classes of RF satellite components and equipment at all frequency bands of interest. Operation in single carrier CW and pulse modulated mode are included, as well as multi-carrier operations. A detailed clause on secondary emission yield is also included.
This standard does not include breakdown processes caused by collisional processes, such as plasma formation.
This standard is applicable to all space missions.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
Raumfahrttechnik - Multipaction, Konzeption und Test
Ingénierie spatiale - Décharge auto-entretenue, conception et essai
La présente norme définit les exigences et recommandations applicables à la conception et aux essais des composants et équipements RF dans le but d’obtenir des performances acceptables pour un fonctionnement en service sans décharge auto-entretenue dans un environnement spatial. La présente norme couvre les aspects suivants :
- exigences relatives à la planification des activités de vérification ;
- définition d’un mode de mise en conformité aux exigences ;
- exigences relatives à la marge de conception et d'essai ;
- exigences de conception et d’essai ;
- annexes informatives contenant des recommandations sur les processus de conception et d’essai.
La présente norme vise à garantir une conception et une vérification efficaces des performances de décharge auto-entretenue des équipements et, par conséquent, à produire un haut degré de confiance quant au bon fonctionnement du produit.
La présente norme aborde les événements de décharge auto-entretenue survenant dans toutes les classes de composants et d’équipements RF à toutes les bandes de fréquences visées dans des conditions de vide poussé (pression inférieure à 10-5 hPa). Elle couvre également les opérations en mode onde entretenue à une seule porteuse et en mode modulation d’impulsions, ainsi que les opérations non modulées à plusieurs porteuses. Un paragraphe détaillé a également été ajouté sur le rendement d’émission secondaire.
La présente norme ne couvre pas les processus de claquage dus aux collisions, comme la plasmification.
La présente norme s’applique à toutes les missions spatiales.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d’un projet spatial, conformément à l’ECSS-S-ST-00.
