The PRobe far-Infrared Mission for Astrophysics (PRIMA) is a future cryogenic space observatory that will revolutionize study of evolving galaxies and forming planetary systems with highly-sensitive far-infrared (far-IR) imaging and spectroscopy. PRIMA’s spectrometer, the Far-InfraRed Enhanced Survey Spectrometer (FIRESS), will deploy kilo-pixel aluminum kinetic inductance detector (KID) arrays covering wavelengths from 24-235 μm. Here we present optical characterization of a prototype FIRESS array operating at 25 μm. We employ a blackbody modulation technique to measure the detector responsivity, and discuss methods for reducing 1/f noise from the multi-tone readout electronics. We measure an NEP below 3.5 × 10−20 W/ √ Hz at 10 Hz accross the array, which exceeds the requirement to be limited by the astrophysical background limit for PRIMA’s FIRESS spectrometer. We discuss limitations of the multi-tone readout and compare results to measurements with a single-tone readout system.

The Probe far-Infrared Mission for Astrophysics (PRIMA) is a proposed space observatory which will use arrays of thousands of kinetic inductance detectors (KIDs) to perform low- and moderate-resolution spectroscopy throughout the far-infrared. The detectors must have noise equivalent powers (NEPs) at or below 1×10−19 W Hz−1/2 to be subdominant to noise from sky backgrounds and thermal noise from PRIMA’s cryogenically cooled primary mirror. Using a Radio Frequency System on a Chip for multitone readout, we measure the NEPs of detectors on a flight-like array designed to observe at a wavelength of 210 μm. We find that 92% of the KIDs measured have an NEP below 1 × 10−19 W Hz−1/2 at a noise frequency of 10 Hz.
