The Dark Energy Survey openParDESclosePar is currently the pre-eminent optical-near-IR survey for cosmology. DES uses four probes to study the physical nature of dark energy comma including clusters of galaxies. To unlock the full potential of DES clusters comma we require precise information of the galaxy-richness to halo-mass scaling relation comma i.e. its slope comma normalisation comma and scatter. Of these comma the least well known is the scatter. Therefore comma one of the highest priorities for DES is to improve measurements of the scatter openParand its evolutionclosePar. For this comma X-ray observations of a statistically complete sample are essential openPararchival comma including serendipitous comma observations are insufficientclosePar. We propose XMM observations openPartotaling 283ksclosePar of 14 DES clusters comma to complete a sample of 40 of the richest clusters in DES
