Suits Group


Femto Lab

In the Suits Group femtolab, we are implementing the strong field ionization-induced Coulomb explosion of small molecules using a Wyvern 1000 (KM Labs) providing 3 mJ/pulse output with femtosecond temporal width. In this lab, we use the multimass coincidence detection method developed by the Wen Li group [1]. Using this method we are able to reconstruct the three dimensional ion distribution by matching ion events obtained from a photomultiplier tube (PMT) connected to a high speed digitizer and a fast-frame CMOS camera. The effort is currently led by post-doc Graham Cooper and graduate student Tahereh Alavi.
