Slide 2 of 7

Testing thin grazing-incidence X-ray mirrors at MSFC X-ray test beam: guide tube from X-ray source to chamber (left); detector end of closed chamber (center); and Technology Demonstration Module (TDM), stage stack, and aperture mask in opened chamber (right).


Significance: This slumped glass technique provided some of the world’s best thin grazing-angle X-ray mirror performance at the time, and was the predecessor for even better single-crystal silicon mirrors that are baselined for Lynx X-ray flagship mission concept

Project Title: Next Generation X-ray Optics: High Resolution ,Light Weight, and Low Cost

PI: Zhang, William (GSFC)

Scanning Electron Microscope (SEM) bottom view image of prototype X-ray Critical-Angle Transmission (CAT) grating


Significance: Highest-resolution X-ray grating technology; baselined for Lynx X-ray flagship mission concept

Project Title: Development of Fabrication Process for X-Ray CAT Gratings

PI: Mark Schattenburg (MIT Kavli Institute for Astrophysics and Space Research)

Slide 4 of 7

Scanning Electron Microscope (SEM) of ATHENA Transition-Edge-Sensor (TES) arrays (32×32 pixels on 250-µm pitch)


Significance: TES microcalorimeters offer energy resolution for advanced X-ray observatories such as the European ATHENA mission

Project Title: High-Resolution Imaging X-ray Spectrometer

PI: Caroline Kilbourne (GSFC)

Slide 5 of 7

Mirror bonded to metrology mount during testing with piezo cell leads visible (piezo layer is hidden on the bottom side) as part of development effort of adjustable thin X-ray mirrors


Significance: Adjustable X-ray optics are a backup technology for the Lynx large mission concept

Project Title: Adjustable X-ray Optics with Sub-Arcsecond Imaging

PI: Paul Reid (SAO)

Slide 6 of 7

A pre-master with radial grooves at high density (~6100 grooves/mm), laminar grating in single crystal Si on path to developing off-plane X-ray reflection grating


Significance: X-ray reflection gratings enable high throughput, high spectral resolving power below 2 keV, a spectral band holding major astrophysics interest

Project Title: Off-Plane Grating Arrays for Future Missions

PI: Randall McEntaffer (PSU)

Slide 7 of 7

Lab test setup with 1570-nm laser (right hand side) locked to quartz cavity (center, white)


Significance:A highly stable laser simultaneously locked to a cavity and a molecular transition at a telecom wavelength can provide a highly coherent light source for future missions

Project Title: Laser Stabilization with CO

PI: John Lipa (Stanford University)
