Video demonstrates how to use an FEL

JRM Professor Daniel Rolles and his group have published a video article in JoVE, the Journal of Visualized Experiments. They describe the key steps for performing and analyzing pump-probe experiments combining a femtosecond optical laser with a free-electron laser in order to study ultrafast photochemical reactions in gas-phase molecules. This work utilizes the CAMP instrument at FLASH, a soft x-ray free electron laser that is part of the German DESY laboratory.
