Abstract

The KLEVER experiment aims to measure \rm BR(KL → π0 νν), supplementing the ongoing NA62 measurement of \rm BR(K+ → π+ νν), to provide new input on CKM unitarity and potentially new physics. KLEVER is undergoing continuous development, with particular efforts focused on the design of the target and the beamline. As described here, adaptations are required relative to the K12 beamline in its current format, and a series of simulations has been performed to ensure that an adequate particle flux can be achieved while simultaneously suppressing problematic backgrounds.
