Title:
流れ及び１投与量の変動を減少させる方法によるアスペクト比が大きい物体への異なるコーティング
Document Type and Number:
Japanese Patent JP6899868
Kind Code:
B2
Abstract:
A channel electron multiplier having a high aspect ratio and differential coatings along its channel length is disclosed. The elongated tube (12) has an input end (14), an output end (16), and an internal surface (18) extending along the length of the tube between the input end and the output end. The channel electron multiplier also has first and second conductive layers (21, 23) located on the interior in adjacent zones on the surface of the tube (12). The first conductive layer (21) is selected to provide a first electrical resistance, a first electron emission characteristic, or both, and the second conductive layer (23) is selected to provide a second electrical resistance, a second electron emission characteristic, or both. A method of making a channel electron multiplier having two or more different conductive layers is also disclosed.
