Electron Bombarded, Back-Illuminated CCD Sensors . ... EBCCD PERFORMANCE: EBS Gain . ... To the first order, the signal gain in the EBCCD is proportional to the kinetic energy of the photoelectrons prior to their impinging on the CCD back surface. ... To obtain EBS gain in the active material, it is necessary for the photoelectron to enter the pixel from the back surface of the CCD -- away from the gate structures that dissipate the electron energy. ... The EBCCD EBS gain was tested using two methods. ...

... Supernova explosion   in a binary is treated as an instantaneous mass loss of the exploding star. ... In this case, the eccentricity and semi-major axis of the binary after the explosion can be straightforwardly calculated (Boersma, 1961[ 21 ]). ... Then, the transition to a new system barycenter frame is made (at this point the spatial velocity of the new center of mass of the binary is computed), . ... During the CE stage, an effective spiral-in   of the binary components occurs. ...
