#AthenaNuggets: Balancing on the Edge: Detecting X-rays with Transition Edge Sensors
In the AthenaNugget #21, Simon Bandler talks about the temperature sensor technology of the X-IFU instrument, called a transition-edge sensor (TES). Simon explains how a TES works as well as how the team developing the X-IFU sensors has been making progress in the past decade to achieve the required exquisite energy resolution of the instrument.
