The SLAC Linear Coherent Light Source (LCLS) is the world’s first hard X-ray free electron laser. It opened the door to revolutionary experiments in atomic and molecular dynamics. A major upgrade (LCLS-II) is now underway. A 4 GeV superconducting electron linear accelerator will be installed in the LCLS tunnel, enabling an increase in the repetition rate from 120 to 1 million pulses per second.
As previously was the case for LCLS, a new generation of detectors needs to be developed to exploit the new capabilities of LCLS-II. Currently available large area forward scattering detectors for soft x-rays are still scientific CCDs, with limited dynamic range and frame readout rate. To address the demands of new experiments, we started a new R&D project: FLORA, the Fermilab-LCLS CMOS 3D-integRated detector with Autogain. Building on more than a decade of experience in similar detector development and taking advantage of the recent advances in CMOS imaging sensors and 3D interconnects, we intend to provide a very high frame readout detector with very low noise and high maximum signal suitable for LCLS-II. Challenges and current status will be presented.
