A constant momentum mass spectrometer with a two-dimensional ion detector in conjunction with a pulsed vacuum ultraviolet laser is used for the simultaneous measurement of the translational energy distributions of many different fragments. A description of the apparatus and its performance are presented. Preliminary experimental results on the photodissociation of toluene and benzene are given.

新型的質譜儀-結合固定的離子動量、二維離子影像偵測器及脈衝式真空子外光雷射-可用來同時偵測許多分解碎片的速度分佈。本文詳細說明這新型質譜儀的特性及功能，以及其在苯及甲苯光分解上的應用。
