Research by Brett Kelly (former MED intern and UC Berkeley PhD student), Maxim Shusteff (MED), Chris Spadaccini (ENG) and colleagues at UC Berkeley was featured on a CBS news report on March 31, 2019. The news segment highlighted joint work on a 3D printing method that uses tomographic reconstruction for volumetric printing.
The hardware for the technology is inexpensive, boding well for its adoption as a commercial product. Another advantage is the reusability of materials, the speed of the process, and the fact that it builds a component all at once rather than in a layer-by-layer fashion.
LLNL's warm-electron-beam ion trap (WEBIT) has been delivered to the NASA/Goddard Space Flight Center, for use in calibrating the Resolve quantum microcalorimeter x-ray spectrometer. Resolve will be launched on the x-ray imaging and spectroscopy mission (XRISM) in 2022, and will measure x-ray emission from celestial sources across the 0.3 to 12 keV x-ray band, with a near constant-energy resolution of ~5 electron volts.
X-ray emission from highly charged ions produced in WEBIT, such as He-like oxygen and He-like neon, provides a significant improvement in accuracy over characteristic lines produced by standard x-ray tubes typically used for calibration purposes. WEBIT will be used as a calibration instrument for Resolve at different stages of assembly over the coming year.
LLNL is an investigator institution for the XRISM satellite, funded by NASA/GSFC to provide the WEBIT for calibration, support calibration measurements of the infrared blocking filter employed by Resolve, and provide laboratory astrophysics measurements using LLNL's EBIT-I and SuperEBIT between now and 2024. LLNL's Megan Eckart (PHYS) is the calibration lead for the XRISM/Resolve instrument and Gregory Brown and Natalie Hell (both PHYS) are members of the XRISM science working group and Resolve instrument team.
