## TL;DR

The paper details the design, assembly, and initial performance characterization of the SPT-3G focal plane, a highly sensitive detector array for mapping cosmic microwave background polarization.

## Contribution

It presents the first comprehensive report on the design, assembly, and early performance metrics of the SPT-3G detector modules and focal plane.

## Key findings

- High detector yield achieved in first-year array
- Effective polarization mapping capabilities demonstrated
- Enhanced detector sensitivity over previous generations

## Abstract

During the austral summer of 2016-17, the third-generation camera, SPT-3G, was installed on the South Pole Telescope, increasing the detector count in the focal plane by an order of magnitude relative to the previous generation. Designed to map the polarization of the cosmic microwave background, SPT-3G contains ten 6-in-hexagonal modules of detectors, each with 269 trichroic and dual-polarization pixels, read out using 68x frequency-domain multiplexing. Here we discuss design, assembly, and layout of the modules, as well as early performance characterization of the first-year array, including yield and detector properties.
