TL;DR: In this article , the authors report measurements of the IQF for proton, an appropriate target for searches of dark matter candidates with a mass of approximately $1~\textrm{GeV}$$.

TL;DR: In this article , the effect of strain-induced martensitic transformation and its reversion on the microstructure evolution and localised corrosion of 2304 lean duplex stainless steel (LDSS) was investigated.

TL;DR: A high-spin level structure of the nucleus 154Tm has been established for the first time up to 6.14 MeV in this article, which is compared to other structures observed in N = 85 neighbouring nuclei.

TL;DR: In this article, the angular power spectrum of the Cosmic Microwave Background (CMB) temperature anisotropies using the data from the last Archeops flight was improved by using the 6 most sensitive photometric pixels in the CMB bands centered at 143 and 217 GHz and 20% of the sky mostly clear of foregrounds.

Abstract: Low-pressure gaseous TPCs are well suited detectors to correlate the directions of nuclear recoils to the galactic Dark Matter (DM) halo. Indeed, in addition to providing a measure of the energy deposition due to the elastic scattering of a DM particle on a nucleus in the target gas, they allow for the reconstruction of the track of the recoiling nucleus. In order to exclude the background events originating from radioactive decays on the surfaces of the detector materials within the drift volume, efforts are ongoing to precisely localize the track nuclear recoil in the drift volume along the axis perpendicular to the cathode plane. We report here the implementation of the measure of the signal induced on the cathode by the motion of the primary electrons toward the anode in a MIMAC chamber. As a validation, we performed an independent measurement of the drift velocity of the electrons in the considered gas mixture, correlating in time the cathode signal with the measure of the arrival times of the electrons on the anode.
