Direct Electron DE-12 direct detection device support¶

CMOS-based direct detection device (DDD) is a new generation of digital camera that can be used with electron microscope. We currently support DE-12 from Direct Electron which is a retractable camera with also an off-axis small scintillator-coupled light-sensitive CMOS survey camera.

The functions can be performed in version 2.2 include:

• Acquiring summed frame image thru Leginon
• Triggering raw frame saving
• Transferring raw frame images off solide-state drive of DE-12 during data collection to a network drive.
• Compiling corrected movie stack with Appion using bright and dark images acquired in Leginon
