X-SORTER\: X-ray Survey Of meRging clusTErs in Redmapper

We propose a firstlook survey of twelve galaxy clusters that, based on opticalselection criteria and archival Xray data of similarly selected clusters, arevery likely to be bimodal merging clusters capable of constraining dark matterproperties. The candidates have \\ge2\\sigma RASS excesses but otherwise havenot been studied with Xrays. By locating the Xray peak(s) well enough todetermine if they have separated from the galaxies, the survey has the potentialto discover new laboratories to probe the nature of dark matter. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
