Description

The Einstein Telescope has begun to transition from ‘concept’ to ‘project’ – meaning the tricky work of integrating the many essential technologies, currently still in R&D, into one coherent detector design. Over the last two years, intensive efforts have resulted in new optical layouts, informed by basic optical requirements towards the sensitivity and controllability of each interferometer, but also by constraints from the wider subsystems of ET (e.g. suspensions, cryogenics and vacuum), and mechanical and civil engineering needs for the underground facility.

In this talk, and accompanying poster (#44), we share the current baseline designs for ET’s optical layouts and the thought processes behind it.
