Response of scCVD Diamond Under Sub-Bandgap Irradiations Measured by the CAPTAN Readout System
نویسنده
چکیده
The radiation hardness of diamonds makes them a strong candidate to replace the inner most part of the CMS tracking detector. Polycrystalline diamond has been shown to regain some its CCD under sub-bandgap irradiations due to the depolarization of the diamond sensor. Monocrystalline diamonds that have suffered proton radiation damage exhibit a similar CCD reduction due to polarization. This study shows that monocrystalline diamond sensors can benefit from sub-bandgap irradiations in a similar manner observed in the depolarization effect seen in polycrystalline diamond sensors.

Introduction: Three physical conditions caused an external beam designated as a small field. The first is the loss of lateral charged particle equilibrium. The second is the effect of collimators on the primary photon source occlusion. The third condition is the size of the detector which is large compared to the field size. The most obvious perturbation effects in last condit...

In order to improve photocatalytic activities of the pure anatase TiO2 under UV and visible light irradiations, a novel and efficient N-doped TiO2 photocatalyst was prepared by sol-gel method. N-doped titania is prepared using the various nitrogen sources such as: triethylamine, N,N,N’,N’-tetramethylethane-1,2-diamine, ethyldiamine, 1,2-phenylenediamine, propanolamine, and...
متن کاملGeneration and transport of photoexcited electrons in single-crystal diamond
We report time-dependent photocurrent and transport measurements of sub-bandgap photoexcited carriers in nitrogen-rich type Ib , single-crystal diamond. Transient carrier dynamics are characteristic of trapping conduction with long charge storage lifetimes of 3 hours. By measuring the photoexcited Hall effect, we confirm that the charge carriers are electrons and by varying the excitation energ...

We have fabricated diamond-like silicon photonic crystals through a sequential silica/silicon chemical vapor deposition (CVD) process from the corresponding polymer templates photopatterned by holographic lithography. Core-shell morphology is revealed due to the partial backfilling of the interstitial pores. To model the shell formation and investigate its effect to the bandgap properties, we d...

Background: This study investigated the effects of some important meteorological parameters and filler type compounds on phytotoxicity of captan in peach trees in the north of Iran. Captan is a phthalimide fungicide which has frequently been used in northern regions of Iran to control certain plant diseases. This fungicide has caused intense phytotoxicity in peach trees which was first observ...
