Abstract
Disclosed herein is an X-ray detector comprises: an X-ray absorption layer configured to absorb X-ray photons; an electronics layer comprising an electronics system configured to process or interpret signals generated by the X-ray photons incident on the X-ray absorption layer; and a temperature driver in the X-ray absorption layer or the electronics layer.
Claims14
A method comprising:
- setting a layer of a first material to a first temperature, wherein the layer of the first material is an X-ray absorption layer;
- setting a layer of a second material to a second temperature, wherein the layer of the second material is an electronics layer comprising an electronics system including at least one voltage comparator;
- wherein the first material and the second material have different coefficients of thermal expansion;
- bonding the layer of the first material and the layer of the second material while the layer of the first material is at the first temperature and the layer of the second material is at the second temperature;
- changing temperatures of the layer of the first material and the layer of the second material toward a third temperature while maintaining differences between relative thermal expansions of the layers to be less than 10% at all times until the layers reach the third temperature;
- wherein changing the temperatures of the layer of the first material and the layer of the second material toward the third temperature comprises using a temperature driver in the layer of the first material or the layer of the second material.
