Velocity map imaging: from molecules to clusters, nanoparticles and aerosols — •Michal Farnik, Viktoriya Poterya, Jozef Lengyel, Andriy Pysanenko, Pavla Svrckova, and Jaroslav Kocisek — J. Heyrovsky Institute of Physical Chemistry, ASCR, Dolejskova 3, 18223 Prague 8

We will present several experiments with large clusters and nanoparticles performed with our cluster beam (CLUB) apparatus which has recently been upgraded with velocity map imaging (VMI) system. The unique and versatile apparatus allows for various experiments besides VMI including, e.g., high resolution mass spectrometry, particle cross section measurements etc. Combination of these experiments can lead to unprecedented detailed information about the dynamics of photochemistry and photophysics even in large clusters. This will be illustrated for systems of atmospheric relevance such as hydrogen halides and freons on/in ice nanoparticles.
