< Topic >Low power low the data acquisition system for the radiation detector whose offer of operation, complete energy level and time discrimination performance of noise and offer of digital output are possible is offered.SolutionsFor the specific application for read-out which possesses the multiple channels where each has the time discriminating circuit and the energy discriminating circuit being the integrated circuit (ASIC), in order to receive the multiple signals from the semiconductor radiation detector, it is the data acquisition system which includes ASIC which is formed. This data acquisition system has furthermore, as it makes join with ASIC electrically, in order to offer the reference signal which is used for the generation of the digital output from ASIC to ASIC, being the controller which is made to join electrically vis-a-vis digital anti- analog converter (DAC) and ASIC and DAC which are formed, in order to make the reference signal ASIC OFFER, in order to command to DAC, the controller which is formed and.< Choice figure >Drawing 8【課題】低パワー低ノイズの動作、完全なエネルギーレベル及び時間弁別性能の提供並びにディジタル出力の提供が可能な放射線検出器向けのデータ収集システムを提供する。【解決手段】その各々が時間弁別回路及びエネルギー弁別回路を有する複数のチャンネルを有する読み出し用特定用途向け集積回路(ASIC)であって、半導体放射線検出器から複数の信号を受け取るように構成されたASICを含むデータ収集システムである。本データ収集システムはさらに、ASICと電気的に結合させると共にASICからのディジタル出力の生成に使用される基準信号をASICに提供するように構成されたディジタル対アナログ変換器(DAC)と、ASIC並びにDACに対して電気的に結合させた制御器であって、基準信号をASICに提供させるようにDACに指令するように構成された制御器と、を備える。【選択図】図8
