UV Contrast Performance and Yield Improvement of the NGMSA for Use on HWO
We will be following a plan of work that follows on from FY23 IRAD work to measure the contrast performance of next generation micro shutter arrays (NGMSAs), as well as an investigation of electrostatic repeatability issues associated with shutter open/close and manufacture shorts in the silicon structure. Our work will demonstrate not only the performance of the device but the control and manufacturability of the shutters and their blades as well as control of the light shield structure to prev...
