Pulse height spectra from the three detectors irradiated with an 241Am α resource. The voltage on the detector was set to best value and the info was put up-processed (smoothed) to minimize the overlap. Insert: Geant four simulation on the incoming α particle spectrum.

The X-ray detection general performance of polycrystalline CVD diamond with pulsed laser deposited carbon electrode

Darkish current and photocurrent are important ways to characterize the electrical Homes of the radiation detector. Fig. five(a) and (b) exhibit the dark current (Id) density and photocurrent (Ip) density for each unit region on the electrode pad of the two diamond detectors we fabricated by using their IV curves. The photocurrent was calculated less than X-ray radiation created from an Ag target that has a tube operated at 10kV and 40kV acceleration voltage with equivalent currents. It can be witnessed that the darkish recent is linear While using the applied subject for that fabricated SCD detector though the PCD detector is nonlinear above The complete voltage selection measured and will become around linear for your larger applied fields.

It's found from Fig. 8 that for the fabricated SCD detector the peak place will increase to its highest worth while the resolution decreases to its finest benefit as voltage improves to 200V and variations minimally outside of this voltage. With the comparison detector nonetheless, the peak place and also the Vitality resolution only achieve their greatest and optimal values at 300V. This may be understood from The point that the SCD movie in our fabricated detector is barely three hundred μm thick Which of the comparison detector is five hundred μm.

If you prefer to a quotation or maybe more specifics of our products and solutions, you should leave us a message, will reply you as soon as possible.

Peak situation and backbone with the measured 241Am α spectra for various voltages applied about the fabricated SCD detector as well as comparison detector.

Outstanding development in CVD methods of diamond synthesis has built it attainable to prepare diamonds suitable for radiation detection with tailor-made Homes on regime foundation.

Also, Though the PCD detector On this work did not perform and also the fabricated SCD detector, It might be fascinating to investigate feasible methods to further improve them, like growing the grain sizing, decreasing the movie thickness, accomplishing pre-irradiation operation and possibly screening the result of various polycrystalline textures. We've been presently Functioning in these directions.

Figure 4. Temperature dependence on the CCE extracted from IBIC spectra attained by two MeV protons for various detector concentrate on locations: 6 irradiated areas and the pristine diamond space.
