Summary:To provide a detector configured to improve the resistance to aging due to radiation, and a detection system.SOLUTION: A detector has a unit cell array in which a plurality of unit cells are arranged. The plurality of unit cells include: a first unit cell having a first conversion element that converts incident energy lines into signal charges to be accumulated, and a first amplification transistor with a control electrode connected to the first conversion element, and configured to amplify the signal charges by the first amplification transistor for output; and a second unit cell having a second amplification transistor with a control electrode connected to a constant voltage source, and configured to output a signal corresponding to the voltage of the constant voltage source by the second amplification transistor. The first unit cell and the second unit cell are arranged in an incident region configured so that the energy lines are made incident, out of the unit cell arrays.SELECTED DRAWING: Figure 1 【課題】放射線による経年劣化への耐性を向上可能な検出器及び検出システムを提供する。【解決手段】検出器は、複数の単位セルが配列された単位セルアレイを有する。前記複数の単位セルは、入射したエネルギー線を信号電荷に変換して蓄積する第一の変換素子と、制御電極を前記第一の変換素子に接続された第一の増幅トランジスタと、を有し、前記第一の増幅トランジスタにより前記信号電荷を増幅して出力する第一の単位セルと、制御電極を定電圧源に接続された第二の増幅トランジスタを有し、前記第二の増幅トランジスタにより前記定電圧源の電圧に応じた信号を出力する第二の単位セルと、を含み、前記第一の単位セル及び前記第二の単位セルは、前記単位セルアレイのうち前記エネルギー線が入射するように構成された入射領域内に配置されている。【選択図】図1
