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.

The concept of a traveling-wave direct energy converter (TWDEC) to recover the energy of 14.7-MeV protons produced by D-3He fusion has been proposed. In TWDEC, the protons are velocity modulated in the modulator to form a bunched beam and then decelerated by the traveling wave excited in the decelerator. A proof-of-principle experiment of TWDEC is performed using a low-energy ion beam. Characteristics of velocity modulation and bunching are measured and compared with theory. It is demonstrated that the beam is decelerated by the traveling wave when the phase velocity and the phase of the wave are adjusted with respect to those of the bunched beam.
