- コンピューター(6)と接続可能で、原子力環境(10)内の被検査体(12)に対する超音波検査作業を行うためにツール(8)によって当該原子力環境に搬入可能な構造のフェイズドアレイ振動子装置(4)であって、当該フェイズドアレイ振動子装置は、
超音波検査作業の少なくとも一部を実施中に当該被検査体と係合する構造の係合面(66)を備えた基部(32)を有するハウジング(18)と、
各々が当該基部上にあって複数の超音波素子(26)を具備する、第1のPASA(24A)、第2のPASA(24B)、第3のPASA(24C)、第4のPASA(24D)、第5のPASA(24E)、第6のPASA(24F)から成る複数のフェイズドアレイサブアセンブリ(PASA)(24)と、
当該第1のPASAは、前記係合面に対する第1の斜角(86、88)と、第1の超音波信号(91)を被検査体の内部に出力する構造を有し、

当該第3のPASAは、前記係合面に対する第3の斜角(86、88)と、第3の超音波信号(95)を被検査体の内部に出力する構造を有し、
当該第4のPASAは、前記係合面に対する第4の斜角(86、90)と、被検査体の傷情報を含む当該第1の超音波信号の少なくとも一部の反射波を受信し、それに応答して、コンピューターが検知可能な第1の出力信号を発生する構造を有し、
当該第5のPASAは、前記係合面に対する第5の斜角(86、90)と、被検査体の傷情報を含む当該第2の超音波信号の少なくとも一部の反射波を受信し、それに応答して、コンピューターが検知可能な第2の出力信号を発生する構造を有し、
当該第6のPASAは、前記係合面に対する第6の斜角(86、90)と、被検査体の傷情報を含む当該第3の超音波信号の少なくとも一部の反射波を受信し、それに応答して、コンピューターが検知可能な第3の出力信号を発生する構造を有し、
当該第1のPASAは、被検査体の内部に向かうように当該第1の超音波信号を当該係合面の上から見て当該ハウジングからその外部に向かうほぼ第1の方向(92)に発信させるべく当該基部上に配置され、当該第2のPASAは、被検査体の内部に向かうように当該第2の超音波信号を当該係合面の上から見て当該ハウジングからその外部に向かうほぼ第2の方向(94)に発信させるべく当該基部の上に配置され、当該第1の方向と当該第2の方向は実質的に互いに反対向きであり、
当該第3のPASAは、被検査体の内部に向かうように当該第3の超音波信号を当該係合面の上から見て当該ハウジングからその外部に向かうほぼ第3の方向(96)に発信させるべく当該基部の上に配置され、当該第3の方向は当該第1の方向と当該第2の方向に対して実質的に垂直である、フェイズドアレイ振動子装置。 - 当該ハウジングはさらに、各々がくさび状の構造で当該基部上にある、第1の支台(48)、第2の支台(50)、第3の支台(54)より成る複数の支台を有し、当該第1のPASAと当該第4のPASAは当該第1の支台上にあり、当該第2のPASAと当該第5のPASAは当該第2の支台上にあり、当該第3のPASAと当該第6のPASAは当該第3の支台上にある、請求項1のフェイズドアレイ振動子装置。
