Abstract
The Terahertz Intensity Mapper (TIM) aims to investigate star formation trends in dust-obscured galaxies during the peak of cosmic star formation by measuring the redshifted 157.7 μm line of singly ionized carbon ([CII]). TIM utilizes two long-slit grating spectrometers, each equipped with an array of horn-coupled aluminum kinetic inductance detectors (KIDs). Designs aimed for a 50-micron uniform boss height in our hornblock arrays, but measurements show non-uniformity in these heights. Sonnet simulations, considering different boss heights and IDC parameters, reveal insights into the impact of various boss heights on the resonance frequencies of the KIDs. Anticipating these frequencies lets us strategically adjust detector designs for optimal performance, compensating for non-ideal boss heights on the array. We will present the study's findings and implications for optimizing KID performance.
