Harmonic Slip-Stacking

Slip-stacking is a particle acceleration technique used at Fermilab to increase Main Injector intensity by combining two beams at the cost of longitudinal beam quality.In a conventional beam line, a single beam is typically accelerated and delivered to the experimental area without combining it with another beam

Development of a colinear Second-Harmonic Orthogonal Polarization (SHOP) interferometer for electron areal density measurements in Magnetically Insulated Transmission Lines (MITLs)

Experimental measurements of low density plasmas forming in Magnetically Insulated Transmission Line (MITL) regions are desired to improve our understanding of current loss and power flow. Therefore, a new optical interferometer diagnostic was commissioned via this LDRD project. To measure the expected 10 13 - 10 17 cm -3 electron densities inside the 0.5 - 6 mm Anode-Cathode (A-K) gaps, a colinear SHOP interferometer diagnostic was constructed. The diagnostic was initially fielded on the University of New Mexico (UNM) Helicon-Cathode (HelCat) plasma device which provided a highly repeatable and well understood plasma source for which the colinear SHOP interferometer’s functionality could be verified and measured. Utilizing the highly repeatable plasma source and shot averaging, the interferometer was able to achieve an areal density sensitivity of 1×10 14 cm -2 . This work at UNM lead to a Review of Scientific Instruments (RSI) publication [20], DOI:10.1063/5.0101687. After the diagnostic’s capability was proven at UNM, the colinear SHOP interferometer was commissioned for use on the Sandia National Laboratories (SNL) Mykonos accelerator. Here, it provided the first temporal areal density measurements of plasma formation in a parallel plate MITL. The diagnostic was able to achieve a single shot (no multi-shot averaging like at UNM) areal density sensitivity of 1×10 15 cm -2 along a ~ 2mm probing path length, which provided adequate capability to conduct fundamental physics research of MITL plasma formation. CHICAGO and ALEGRA simulations support the diagnostics experimental findings. More experimental and computational work will continue, likely leading to another publication(s). The smaller scale Mykonos accelerator work has also provided justification that the colinear SHOP interferometer is a capable diagnostic for measuring plasma areal densities in the inner MITL and convolute regions of larger TW-class accelerators like SNL’s Z machine.

TCF Base Commercialization Enabling Final Report: Lab Making Advanced Technology Commercialization Harmonized (MATCH) Prize

The Lab MATCH prize, funded by the Office of Technology Commercialization through the Technology Commercialization Fund, was designed to accelerate the commercialization of national laboratory intellectual property (IP) by incentivizing for-profit companies and startups to license lab IP aiming to enable more affordable, available, reliable and secure energy solutions. The Lab MATCH prize program offers both technical and commercial benefits, aligning with the Department of Energy's (DOE) mission to advance energy solutions through innovation, commercialization, and market-ready deployment. In summary, the Lab MATCH Prize promotes DOE's objectives by marrying technical innovation with commercialization expertise, resulting in scalable, market-ready solutions that strengthen the U.S. economy, advance energy technologies, and reaffirm U.S. leadership in energy innovation.
