Description

Many astronomical observations proved that around 27 % of our universe is made up of dark matter. However, the exact nature of it has not been exactly understood. CRESST is one of several experiments dedicated to find dark matter particles through direct detection. CRESST-II detector modules based on scintillating CaWO4 crystals and operated at mK temperatures have the ability to detect light dark matter particles and to actively suppress the dominating beta/gamma backgrounds originating from natural radioactivity and cosmogenic activation. Especially for light dark matter particles generating low recoil energies, the background discrimination is more challenging. Thus, precise knowledge of the background is crucial for this regime. In this contribution, we will present the status of the Monte-Carlo studies of the electromagnetic background components observed within CRESST-II Phase 2, data taking phase of which has been finished almost a year ago. The results of these studies will be important inputs for the future phases of CRESST, like the upcoming CRESST-III Phase 1, to either detect a dark matter signal or to improve the limits for a null result. In addition, the results of the simulations can be a starting point for future detector developments towards better background suppression.
