Presentation Transcript

  1. X-ray induced molecular fragmentation LCLSII – New Instruments Workshop March 2012 Vladimir Petrovic, Phil Bucksbaum PULSE Institute, Stanford University

  2. X-ray induced molecular fragmentation • Science focus: Capture the correlated motion of ions in molecules during intra-molecular dynamics • Science pay-off opportunity: A unique probe of molecules, complements other methods. S2 S1 S0 CI (S0/S1) c-Z-c HT c-Z-t HT 1,3-cyclohexadiene (CHD) t-Z-t HT 1,3,5-hexatriene (HT)

  3. X-ray induced molecular fragmentation Source requirements: <0.5 eV Transform-limited x-rays tunable to the vicinity of absorption edges of C, N, O, or other elements present in the sample. Synchronization to the laser that excites the dynamics. Instrument requirements: Ion VMI; fluorescence detection; sample alignment is also desirable. Expand capabilities of the excitation laser (shorter wavelength, shaping). Ion-ion and electron-ion coincidences (higher data acquisition rates).
