Title:
高密度電子なだれチャンバー変換器を使用する撮像システム
Document Type and Number:
Japanese Patent JP3728700
Kind Code:
B2
Abstract:
An imaging system module comprising: a pair of high density avalanche chamber converters (11, 12) each including alternate layers (15, 16) of conducting and non-conducting material and an array of holes (17) extending through the alternate layers (15, 16), the first converter (11) having conducting elements (18) extending parallel to each other to form a first cathode on or adjacent to a face of the converter (11) and the second converter (11) having conducting elements (19) extending parallel to each other in a direction orthogonal to the conducting elements (18) to form a second cathode on or adjacent to a face of the second converter (12), and an anode (21) formed by parallel conducting elements between the first and second cathodes (18, 19). Radiation incident upon either converter (11, 12) produces an avalanche of charged particles which are attracted towards the anode (21) and the incidence of a charged particle on the anode (21) causes a current pulse in both the first and second cathodes (18, 19).
