San Francisco Art & Athletics, Inc. v. United States Olympic Committee: USOC May Enforce Its Rights in Olympic Without Proof of Confusion

In San Francisco Arts & Athletics, Inc. v. United States Olympic Committee, the United States Supreme Court held that the United States Olympic Committee (USOC) could enforce its statutory rights in the mark OLYMPIC without proving likelihood of customer confusion. Because this holding extended the USOC\u27s trademark rights beyond those engendered by the Lanham Act, the Court was compelled to subject those rights to constitutional scrutiny. The Court\u27s holding prevented San Francisco Arts & Athletics, Inc. (SFAA) from using the word OLYMPIC to promote the Gay Olympic Games. The SFAA decision will probably affect future analyses of trademark rights and constitutional issues. The Supreme Court not only construed the Amateur Sports Act in such a way that the USOC need not show confusion as to SFAA\u27s use, but also held that the USOC\u27s enforcement of its trademark right against SFAA did not violate the first amendment. Finally, since the court did not consider the USOC to be a government entity, it held that enforcing USOC\u27s OLYMPIC mark rights did not violate the fifth amendment

A Textured Silicon Calorimetric Light Detector

We apply the standard photovoltaic technique of texturing to reduce the reflectivity of silicon cryogenic calorimetric light detectors. In the case of photons with random incidence angles, absorption is compatible with the increase in surface area. For the geometrically thin detectors studied, energy resolution from athermal phonons, dominated by position dependence, is proportional to the surface-to-volume ratio. With the CaWO4 scintillating crystal used as light source, the time constants of the calorimeter should be adapted to the relatively slow light-emission times.Comment: Submitted to Journal of Applied Physic

The ν\nu-cleus experiment: A gram-scale fiducial-volume cryogenic detector for the first detection of coherent neutrino-nucleus scattering

We discuss a small-scale experiment, called $\nu$-cleus, for the first detection of coherent neutrino-nucleus scattering by probing nuclear-recoil energies down to the 10 eV-regime. The detector consists of low-threshold CaWO$_4$ and Al$_2$O$_3$ calorimeter arrays with a total mass of about 10 g and several cryogenic veto detectors operated at millikelvin temperatures. Realizing a fiducial volume and a multi-element target, the detector enables active discrimination of $\gamma$, neutron and surface backgrounds. A first prototype Al$_2$O$_3$ device, operated above ground in a setup without shielding, has achieved an energy threshold of ${\sim20}$ eV and further improvements are in reach. A sensitivity study for the detection of coherent neutrino scattering at nuclear power plants shows a unique discovery potential (5$\sigma$) within a measuring time of ${\lesssim2}$ weeks. Furthermore, a site at a thermal research reactor and the use of a radioactive neutrino source are investigated. With this technology, real-time monitoring of nuclear power plants is feasible.Comment: 14 pages, 19 figure
