Abstract
NIST developed MKID arrays based on TiN/Ti multilayers have been successfully deployed, but the 1/f knee of 1 Hz limits their use in some applications. We have created hybrid TiN-Al MKIDs that combine the low TLS noise of the TiN-Si interface with the high sensitivity and 1/f-noise free Al inductors. These hybrid MKIDs have been designed for the photon loadings of the CCAT-prime Project. A sub-array of devices was fabricated, and initial measurements will be shown that indicate that the devices are photon noise limited at the expected loading, with a 1/f knee below 0.1 Hz.
