Title (EN) CHARGE-GENERATING ELEMENT AND MICROPARTICLE COUNT DETECTOR
(FR) ÉLÉMENT DE GÉNÉRATION DE CHARGE ET DÉTECTEUR DE COMPTAGE DE MICROPARTICULES
(JA) 電荷発生素子及び微粒子数検出器
Abstract:
(EN) This charge-generating element 20 comprises a discharge electrode 24 on the front surface 22a of a dielectric layer 22, and an induction electrode 26 on the back surface 22b thereof, a charge being generated by a discharge when a voltage is applied between the discharge electrode 24 and the induction electrode 26. The discharge electrode 24 has a flat base surface 24a, and a bulging surface 24b having a shape bulging from the base surface 24a. An angle θ of 5° to 45° is formed by the bulging surface 24b and the base surface 24a at an edge E of the discharge electrode 24.
(FR) La présente invention concerne un élément de génération de charge (20) qui comprend une électrode de décharge (24) sur la surface avant (22a) d'une couche diélectrique (22), et une électrode d'induction (26) sur la surface arrière (22b) correspondante, une charge étant générée par une décharge lorsqu'une tension est appliquée entre l'électrode de décharge (24) et l'électrode d'induction (26). L'électrode de décharge (24) présente une surface de base plate (24a), et une surface bombée (24b) ayant une forme bombée à partir de la surface de base (24a). Un angle θ de 5° à 45° est formé par la surface bombée (24b) et la surface de base (24a) au niveau d'un bord (E) de l'électrode de décharge (24).
(JA) 電荷発生素子20は、誘電体層22の表面22aに放電電極24、裏面22bに誘導電極26を有し、放電電極24と誘導電極26との間に電圧が印加されると放電により電荷が発生するものである。放電電極24は、平坦なベース面24aと、そのベース面24aから膨らんだ形状の膨出面24bとを有し、放電電極24のエッジEにおけるベース面24aと膨出面24bとのなす角度θが5°~45°である。
