Abstract :
We present the design of two velocity spectrometers, to be used in the recently approved CKM experiment. CKMʹs main goal is the measurement of the branching ratio of K+→π+νν̄ with a precision of 10%, via decays in flight of the K+. The design of both RICH detectors is based on the SELEX Phototube RICH. We will discuss the design and the expected performance based on studies with SELEX data and Monte Carlo simulations.
