Abstract
Un détecteur de mobilité ionique (10) servant à mesurer la mobilité d'ions comprend une grille obturatrice cylindrique (18) disposée concentriquement par rapport à un collecteur cylindrique (20), un champ électrique étant appliqué radialement entre eux. La présente invention permet de résoudre le problème de la recombinaison au niveau des parois latérales exposées de la region de dérive. La présente invention résout également le problème de la sensibilité en maximalisant la surface de la grille obturatrice (18) et du collecteur (20).
