Someday you will get to play with those electrons!

Razib Obaid is a project scientist at the Linac Coherent Light Source (LCLS) at SLAC in California. LCLS is one of 7 free electron lasers in the collaboration. The facility takes X-ray snapshots of atoms and molecules at work, providing atomic resolution detail on ultrafast timescales to reveal fundamental processes in materials, technology and living things. Its snapshots can be strung together into “molecular movies” that show chemical reactions as they happen.

In Razib’s #LightSourceSelfie, he takes you into the Near Experimental Hall and describes the stunning equipment that is used to undertake the experiments, the science it enables and the possibilities for new science with the upgrade to LCLSII. Razib says, “The best thing about working at a light source is the ability as a user to tap into the enormous scientific resources and experience that exists among the staff and scientists. Not to mention the state of the art instrumentation that you have access to, to realise your science. To my younger self, I would say, keep studying quantum mechanics, someday you will get to play with those electrons.”
