(a) Darkish recent with the fabricated SCD and PCD detectors; (b) Photocurrent from the fabricated SCD and PCD detectors using X-rays irradiation from Ag concentrate on less than distinctive tube voltages Together with the very same beam depth.
The X-ray detection functionality of polycrystalline CVD diamond with pulsed laser deposited carbon electrode
Darkish present-day and photocurrent are essential ways to characterize the electrical Homes on the radiation detector. Fig. 5(a) and (b) present the dark existing (Id) density and photocurrent (Ip) density per device area in the electrode pad of The 2 diamond detectors we fabricated by way of their IV curves. The photocurrent was calculated beneath X-ray radiation generated from an Ag focus on having a tube operated at 10kV and 40kV acceleration voltage with equal currents. It is actually found that the dark current is linear Together with the utilized field for that fabricated SCD detector nevertheless the PCD detector is nonlinear about The entire voltage vary measured and becomes about linear with the much larger utilized fields.
The height positions of the pulse peak spectra of both of those SCD detectors improve as being the voltage raises even though the Power resolutions make improvements to. To the fabricated SCD detector, both equally the height posture and backbone keep on being secure as soon as the bias voltage reaches 200V With all the later on remaining at approximate three.seven%. The resolution in the fabricated SCD detector is pretty much as good as that from the comparison detector when its operational voltage is scaled-down supplied its smaller sized thickness. Using the Hecht product, the gathering efficiency in the fabricated SCD detector is uncovered to be previously mentioned 97% for its optimum bias voltages, and that from the comparison detector is 1-2% lower at the same voltage.

To check the effect of bias voltage within the Electricity resolution and detector steadiness, and also to discover the optimum voltage, we utilized distinctive bias voltage for the detector. Fig. 8 shows the heartbeat peak spectra for various utilized voltages with a set time of ten min and Fig. nine reveals the corresponding relation between the voltage and also the Power resolution and place from the peaks fashioned by the 241Am α particles when using the fabricated SCD detector along with the comparison detector.
