Postdoctoral Appointee - Developing MEMS Based Ultrafast X-ray Optics

A postdoc position is immediately available at the Advanced Photon Source of Argonne National Laboratory. The postdoctoral appointee will develop ultrafast microscale photonics and MEMS (microelectromechanical systems) devices for X-ray optics at synchrotron radiation sources. Some background of the project is given in the publications listed below. The idea is to make highly nonlinear MEMS-based oscillators driven by the storage-ring RF signals to fulfill the function of manipulating X-ray pulses. More specific responsibilities include MEMS design and simulation, testing and characterization of the devices, and designing and executing time-resolved X-ray experiments with MEMS-based X-ray optics.

We are seeking highly motivated candidates to drive the project in an independent manner while interacting closely with senior members of the research group. The term of the positions is typically two years, with the possibility to renew for the 3rd year, contingent on the project process and availability of funds.
