Beam dynamic studies at accelerator system of gun for a self-amplified spontaneous emission free electron laser project
Yıldız, H. Duran; Porsuk, D.; Yıldız, I.; Çakır, Raşit (Elsevier, 2021)One of the important factors in high radiation generation facilities is the production of a high quality electron beam. To do that, the requirements of an optical electron source, such as current, radiation emission, etc. ... -
Binding energies of shallow donors in polar ZnO/ZnBeO quantum well
Çakır, Raşit; Yıldırım, Hasan (Elsevier, 2024)This study examines a single wurtzite ZnO/ZnBeO quantum well structure oriented in the polar c -direction. The focus is on investigating the binding energies associated with an impurity donor atom within this system. To ... -
Design and comparison of superconducting rf gun cavities and beam dynamics for linear electron accelerators
Yıldız, Hatice Duran; Porsuk, D.; Çakır, Raşit; Tugay, H. (Elsevier Science Bv, 2019)Designs and simulations of 1.4, 1.5, 1.6, and 1.8-cell SRF gun cavities are studied at a linear accelerator gun system and they are compared with each other. We obtain high power beam from high energy electron beam produced ... -

Yıldız, Hatice Duran; Çakır, Raşit; Porsuk, D. (Elsevier Science Bv, 2015)Design and simulation of a superconducting gun cavity with 31/2 cells have been studied in order to give the first push to the electron beam for the linear accelerating system at the Institute of Accelerator Technologies ... -
Donor binding energies in single ZnCdO/ZnO quantum well
Çakır, Raşit (Elsevier, 2022)The single wurtzite Zn1-xCdxO/ZnO quantum well structure in polar c-direction is studied and the binding energies of an impurity donor atom are obtained. The Schrodinger and Poisson equations are solved self consistently ... -
Intersubband transitions in nonpolar ZnO/BeMgZnO quantum wells: effects of physical dimension, concentration and donor level
Yıldırım, Hasan; Çakır, Raşit (Igdir University, 2022)Polar ve semipolar yönlerde büyütülen BeMgZnO bariyer tabakaları üzerindeki ZnO kuyu katmanlarının polarizasyon özellikleri araştırıldı. Gevşemiş ve gerilmiş bariyer katmanların durumları göz önünde bulunduruldu. ... -
Polarization effects on intersubband absorption in GaN/ZnGeN2 quantum wells
Çakır, Raşit (Igdir University, 2021)The effects of spontaneous and piezoelectric polarizations on the intersubband absorption in the GaN/ZnGeN2 quantum well are studied. Schrödinger and Poisson equations are solved self-consistently. The first order linear ...
