Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

A thermal model of an OMEGA-scale cryogenic inertial confinement fusion (ICF) target within the layering sphere of the OMEGA Cryogenic Target Positioner was created. A computational fluid dynamics code was used to calculate the temperature profile in the target. The sensitivity of the temperature profiles was modeled for variations in (1) target alignment in the layering sphere, (2) target specifications, and (3) temperature uniformity on the layering sphere’s inner surface. DT-ice non-uniformity in the target was determined by offsetting the center of the ice’s void to a position that minimized the temperature variance of the ice surface. The numerical solutions were compared to analytical solutions when available.
