Megjegyzések:	The Einstein Telescope (ET) is a proposed next-generation, underground gravitational-wave detector to be based in Europe. It will provide about an order of magnitude sensitivity increase with respect to the currently operating detectors and, also extend the observation band targeting frequencies as low as 3 Hz. One of the first decisions that needs to be made is about the future ET site following an in-depth site characterization. Site evaluation and selection is a complicated process, which takes into account science, financial, political, and socio-economic criteria. In this paper, we provide an overview of the site-selection criteria for ET, provide a formalism to evaluate the direct impact of environmental noise on ET sensitivity, and outline the necessary elements of a site-characterization campaign.

Megjegyzések:	Preparations of remeasurement of the Eötvös-Pekár-Fekete (EPF) experiment for the Weak Equivalence Principle were reported in [4]. Here we give a brief overview of the gravity field bias and try to estimate its possible effect on the EPF experiment. We report our first test results in the solar gravity field with Cu-Au and Al-Au pairs. The estimated errors were at level 2?10??, the same accuracy that was obtained by EPF. We also found that angular positions of the balances showed good correlation with bandpass-filtered air pressure variations hence Wiener filtering may significantly reduce this correlated noise. We did not detect any deviation from the equivalence principle considering the estimated measurement error.

Megjegyzések:	Between 1906 and 1908 Roland (Loránd) Eötvös and his colleagues Dezső Pekár and Jenő Fekete made measurements with revolutionary precision (the EPF measurement) for validating the equivalence of gravitational and inertial mass. Almost 80 years later, in 1986, Ephraim Fischbach and his colleagues reanalyzed the results of the EPF measurement and discovered a correlation between the small violations and some atomic parameter. Finally they were unable to reproduce this correlation experimentally, but there is still no valid explanation of these differences in the EPF results. Our analysis of the EPF experiment pointed to a possible bias that justifies repeating the tests under better conditions and using modern new technology. Planning and preliminary measurements started at July of 2017. Participants are from Wigner Research Centre for Physics of the Hungarian Academy of Sciences, Department of Geodesy and Surveying of Budapest University of Technology and Economics (BME), Society for the Unity of Science and Technology (SUST), and the Department of Control Engineering and Information Technology of BME in cooperation with other organizations, departments and experts. After more than one year of thoughtful preparation, in December 2018 preliminary tests have been started in a controlled and undisturbed environment of the Jánossy Underground Physics Laboratory at KFKI, 30 meters below ground level. This paper gives a brief overview of the basic physics, history, preparations and present status of the new experiments. Another good reason for repeating the EPF measurements is that 2019 ? as the 100th anniversary of Eötvös's death ? is referred as "Eötvös year".
