 Built-in self test of high speed analog-to-digital converters / Santin, Edinei (CERN) ; Oliveira, Luis B (Nova U., Lisboa) ; Goes, Joao (Nova U., Lisboa) Signals found in nature need to be converted to the digital domain through analog-to-digital converters (ADCs) to be processed by digital means [1]. [...] 2019. - 7 p.

 The Tracker End-cap Pixel detector for CMS Phase-2 upgrade / Del Burgo, Riccardo (Zurich U.) /CMS Collaboration After the high-luminosity upgrade of the LHC (HL-LHC), the instantaneous luminosity will increase to unprecedented values of $5-7 \times10^{34}\,\mathrm{cm^{-2}s^{-1}}$. In order to cope with these conditions the whole CMS silicon tracker detector will be replaced. [...] CMS-CR-2019-146.- Geneva : CERN, 2019 - 7 p. Fulltext: PDF;

 The hunt for sub-GeV dark matter at neutrino facilities: a survey of past and present experiments / Buonocore, Luca (U. Naples (main) ; INFN, Naples ; U. Zurich (main)) ; deNiverville, Patrick (CERN ; INFN, Milan) ; Frugiuele, Claudia (IBS, Daejeon ; Los Alamos) We survey the sensitivity of past and present neutrino experiments to MeV-GeV scale dark matter, and find that these experiments possess novel sensitivity that has not yet fully explored.
