In context neutral antimatter, gravitational interaction high interest, potentially revealing new that violate weak equivalence principle. Here we report on a successful extension tool from atom optics—the moiré deflectometer—for acceleration slow antiprotons. setup consists two identical transmission gratings and spatially resolving emulsion detector for...

These identification used CMS.
The Resistive Plate Chambers (RPCs) are employed in the CMS Experiment at LHC as dedicated trigger system both barrel and endcap.
