| Research Abstract |
A new crossed molecular beam apparatus with a high-resolution ion imaging detector is described. Two pulsed supersonic molecular beams are crossed at the right angle in a vacuum of 10^<-7> Torr. The collision region is irradiated with a tunable laser pulse that ionizes the scattered particles state-selectively. The generated ions are accelerated by stacked electrodes in a two-dimensional (2D) space focusing mode that increases velocity resolution of the apparatus. A cylindrical hexapole deflector placed in the middle of the time-of-flight mass spectrometer compensates the center-of-mass velocity of the ions and directs them to the center of the 2D imaging detector. Real-time image processing of a CCD camera signal eliminates the blurring of the imaging detector. The performance of the apparatus was examined by observing the inelastic scattering of NO + Ar at the collision energy of 66 meV.The observed multiple rainbow peaks clearly demonstrate high performance of the apparatus.
