Measurements of charge transfer efficiency in a proton-irradiated swept charge device

Proton irradiation of a swept charge device at cryogenic temperature and the subsequent annealing

A number of studies have demonstrated that a room temperature proton irradiation may not be sufficient to provide an accurate estimation of the impact of the space radiation environment on detector performance. This is a result of the relationship between defect mobility and temperature, causing the performance to vary subject to the temperature history of the device from the point at which it ...

Charge -coupled- device charge -collection efficiency and the photon- transfer technique

Relay proton transfer triggered twisted intramolecular charge transfer.

The mechanism for the dual emission of 2-(4'-N,N-dimethylaminophenyl)imidazo[4,5-c]pyridine (DMAPIP-c) in protic solvents was investigated by synthesizing and studying its analogues. Theoretical calculations were carried out to corroborate the experimental findings. The deprotonation studies suggest that the enhancement in the TICT emission of anionic forms of DMAPIP-c is limited to a protic en...

Modelling charge transfer in a radiation damaged Charge Coupled Device for Euclid

As electrons are transferred through a radiation damaged Charge Coupled Device (CCD), they may encounter traps in the silicon in which they will be captured and subsequently released. This capture and release of electrons can lead to a ‘smearing’ of the image. The dynamics of the trapping process can be described through the use of Shockley-Read-Hall theory, in which exponential time constants ...

Determination of Trimethoprim Based on Charge-Transfer Complexes Formation

A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
