4kV～10kV X線ジェネレーター
XMPGはモジュール式10kV @ 10W X線ジェネレーターであり、接地されたフィラメントのX線管駆動を放射電流0～1mAの閉ループフィラメント制御で行います。接地されたフィラメント電源の定格は0～5A @ 3Vdcです。このフィラメント電源には0.5～2.5Aで内部調節可能なフィラメントプリヒート電源と、0～5Aで内部調節可能なフィラメント制限電源が搭載されています。
高電圧プログラムと放射電流プログラムは内部プリセット機能があり、このX線ジェネレーターとのインターフェイスが容易です。別の方法として、お客様の0～10Vdcの信号を用いてこれら2つの信号をリモートで制御することも可能です。高電圧モニター信号と放射電流モニター信号も備わっています。高電圧有効化入力では高電圧出力を制御でき、フィラメント安定出力はフィラメント電流が適切で、X線管がX線を発生していることを示します。
