Disclosed is an X-ray sensor having an active detector region including detector diodes on its surface. The X-ray sensor further includes a junction termination surrounding the surface region including the detector diodes. The junction termination includes a guard arranged closest to the end of the surface region, a field stop outside the guard and at least two field limiting rings, FLRs arranged between the guard and the field stop. A first FLR is arranged at a distance Δfrom the guard selected from the interval [4 μm; 12 μm], a second FLR is arranged at a distance Δfrom the first FLR selected from the interval [6.5 μm; 14 μm], and wherein the distance Δis larger than the distance Δ. The proposed technology also provides a method for constructing such an X-ray sensor and an X-ray imaging system including an X-ray detector system that includes such X-ray sensor.

X-ray sensor having a field limiting ring configuration

An X-ray sensor () having an active detector region including a plurality of detector diodes () arranged on a surface region () of the X-ray sensor (), a junction termination () surrounding the surface area () including the plurality of detector diodes (), the junction termination () including a guard () arranged closest to the end of the surface region (), a field stop () arranged outside the guard () and a number N of field limiting rings, FLRs () arranged between the guard () and the field stop (), wherein each of the FLRs () are placed at positions selected so that distances between different FLRs () and between the guard and the first FLR lie within an effective area, the effective area being bounded by the lines &#x3b1;=(10+1.3&#xd7;(n&#x2212;1)) &#x3bc;m and &#x3b2;=(5+1.05&#xd7;(n&#x2212;1)) &#x3bc;m.

X-ray sensor, method for constructing an x-ray sensor and an x-ray imaging system comprising such an x-ray sensor

There is provided an x-ray sensor () comprising an active detector region including a plurality of detector diodes () at a first side of the sensor, and a common junction termination () at a second opposite side of the sensor. Normally, this implies that the junction termination () is moved from the top side where the active detector area is located to the bottom side of the sensor, allowing for full utilization of the active detector area at the top side with detector diodes to the very edge of the sensor.
