## Abstract

Far-infrared detectors for future cooled space telescopes require ultra-sensitive detectors with optical noise equivalent powers of order 0.2 aW/\\sqrt Hz. This performance has already been demonstrated in arrays of transition edge sensors. A critical step is demonstrating a method of fabrication and assembly that maintains the performance but that is extendable to create large-scale arrays suitable, for example, for application in dispersive spectrometers where it may be advantageous to fabricate the array from smaller sub-arrays. Critical here are the methods of assembly and metrology that maintain the required tolerances on the spatial alignment of the components in order to maintain overall performance. These are discussed and demonstrated.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
