“Teaching To the Test” Family of Fallacies

Revista Iberoamericana de Evaluación Educativa, 2017
This article explains the various meanings and ambiguities of the phrase “teaching to the test” (TttT), describes its history and use as a pejorative, and outlines the policy implications of the popular, but fallacious, belief that “high stakes” testing ...

The CALorimetric Electron Telescope (CALET) for high-energy astroparticle physics on the International Space Station

EPJ Web of Conferences, 2015
The CALorimetric Electron Telescope (CALET) is a space experiment, currently under development by Japan in collaboration with Italy and the United States, which will measure the flux of cosmic-ray electrons (and positrons) up to 20 TeV energy, of gamma ...

Detektoren mit niedrigen Triggerschwellen für die direkte Suche nach leichter Dunkler Materie mit CRESST-III

, 2017
The CRESST experiment aims to directly detect dark matter particles via recoils off nuclei in CaWO4 target crystals. CRESST-III (started 2016) is dedicated to explore the low-mass dark matter regime (O(0.1GeV/c2)).

Neutron Background Studies for the CRESST Dark Matter Experiment

, 2020
The new detection concept applied for the direct WIMP search experiment CRESST II, which enables a clear discrimination between electron recoils and nuclear recoils, will leave neutrons as the main background.

The CRESST-III low-mass WIMP detector [PDF]

, 2016
The next generation direct dark matter experiment CRESST-III has a high potential to significantly increase the sensitivity to low-mass WIMPs (mx ≲10 GeV/c2).

Analysis and modelling for CRESST-II

, 2012
The dark matter search CRESST-II completed its most recent run, Run 32, in 2011. Compared to previous runs, the quantity of data taken in this run increased significantly. In this work, Oxrop, analysis software in use within the CRESST collaboration, is upgraded to analyse this new data.

Development of new cryogenic detectors to extend the physics reach of the CRESST experiment [PDF]

, 2020
The vast presence of dark matter in the Universe is nowadays one of the biggest unresolved mysteries of science. The dark matter problem stems from cosmological and astronomical observations which, however, do not provide any information about the nature

Constraints on self-interaction cross-sections of dark matter in universal bound states from direct detection

European Physical Journal C: Particles and Fields
$$\varLambda $$ Λ -Cold Dark Matter ( $$\varLambda $$ Λ CDM) has been successful at explaining the large-scale structures in the universe but faces severe issues on smaller scales when compared to observations.

Light dark matter investigation with CRESST [PDF]

Proceedings of Neutrino Oscillation Workshop — PoS(NOW2018), 2019
Cryogenic detectors are excellent devices for rare event searches. Thanks to their low energy thresholds, these detectors are at the cutting edge for the investigations of light dark matter (DM). The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) experiment explores with high sensitivity the parameter space of low mass DM ...
