The perspective to build large accelerators based on high gradient superconducting cavities posed a number of new problems that have been mainly addressed in the preparation of the TESLA project. In this paper I briefly discuss the TESLA Collaboration contributions to the state of the art of the SRF technology and how they have been at the basis of the cold choice for the International Linear C...

44 JPT • MARCH 2012 Editor’s note: This is the fifth in a series of articles on the great challenges facing the oil and gas industry as outlined by the SPE Research and Development (R&D) Committee. The R&D challenges comprise broad upstream business needs: increasing recovery factors, in-situ molecular manipulation, carbon capture and sequestration, produced water management, higher resolution ...

Main findings: • Level-based R&D tax credits are subject to a serious deadweight loss. • Increment-based R&D tax credits are not subject to that deadweight loss, but have their own deficiencies. • The bulk of the empirical evidence concludes that there is no crowding-out but also little additionality. • R&D tax incentives have the advantage of being neutral, less costly to administer, and more ...

In this article we consider asymptotics for the spectral function of Schrödinger operators on real line. Let $P\\colon L^2(\\mathbb{R})\\to L^2(\\mathbb{R})$ have form $$ P:=-\\frac{d^2}{dx^2}+W, where $W$ is a self-adjoint first order differential operator with certain modified almost periodic structure. We show that kernel projector, $\\mathbf{1}{(-\\infty,\\lambda^2]}(P)$ has full asymptotic...

The Department of Energy has the responsibility to address the energy, environmental, and nuclear security challenges that face our nation. In support of this mission, it operates national laboratories and scientific user facilities, performs basic and applied research and engineering, and works to assure reliable energy delivery and to maintain our nuclear deterrence capabilities. Despite ubiq...

Recent results on the particle detector R&D for new accelerators are reviewed. Different approaches for the muon systems, hadronic and electromagnetic calorimeters, particle identification devices, and central trackers are discussed. Main emphasis is made on the detectors for the International Linear Collider and Super B-factory. A detailed description of a novel photodetector, a so called Sili...
