Insights from Swift J0243.6+6124 during its 2017-2018 outburst Serim, Muhammed Miraç; Dönmez, Çağatay Kerem; Serim, Danjela; Ducci, Lorenzo; Baykal, Altan; Santangelo, Andrea (2024-06-06)
NA65(DsTau): study of tau neutrino production in p-A interactions Güler, Ali Murat (2024-03-22) The DsTau (NA65) experiment at CERN was proposed to measure an inclusive differential cross-section of Ds production in p-A interactions. As this process is a main source of tau neutrino production, its study is necessary ...
The SND@LHC experiment at CERN Güler, Ali Murat (2024-03-22) SND@LHC is proposed to exploit the high flux of energetic neutrinos of all flavours from the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < η < 8.4, complementary to all the other experiments at the LHC. The ...
On the conditions of applicability of commonly used modification of a fluid model for glow discharge Kudryavtsev, A.; Rafatov, İsmail; Yuan, C. (2024-01-01) The reliability of a numerical model is determined by its the least accurately known component. Such a component in fluid models of glow discharges is the description of electrons, which are far from equilibrium. This is e...
NA65(DsTau): study of tau neutrino production in p-A interactions Yuksel, Emin; Güler, Ali Murat (2023-12-14) The DsTau experiment at CERN-SPS has been proposed to measure an inclusive differential cross-section of a Ds" role="presentation">Ds production with a consecutive decay to tau lepton in p-A interactions. A precise mea...
EFFECT OF DIFFERENT MODELLING APPROACHES FOR SIMULATION OF ATMOSPHERIC PRESSURE GLOW DISCHARGES IN HELIUM EYLENCEOĞLU, ENDER; Rafatov, İsmail; Islamov, Gubad; YEŞİL, CİHAN (2023-08-31)
EFFECT OF THE CATHODE SURFACE TEMPERATURE ON THE CATHODE FALL LAYER PARAMETERS EYLENCEOĞLU, ENDER; Islamov, Gubad; Rafatov, İsmail (2023-08-31)
The effect of SiNx:H stoichiometry on electrical and chemical passivation of Al2O3/SiNx:H stack layer on p-type silicon wafers Canar, Hasan Hüseyin; Bektaş, Gence; Keçeci, Ahmet Emin; Asav, Hasan; Bütüner, Sümeyye Koçak; Arlkan, Bülent; Turan, Raşit (2023-06-27) In this paper, we report on the influence of SiNx:H stoichiometry on Al2O3/SiNx:H passivation stacks. We analyze the fabricated dielectric layers with four methods: FTIR, C-V, PCD and EQE. SiNx:H with a lower refractive in...
Silicon heterojunction solar cell efficiency improvement with wide optical band gap amorphous silicon carbide emitter Salimi, Arghavan; Dönerçark, Ergi; Koç, Mehmet; Turan, Raşit (2023-06-27) Boron doped hydrogenated amorphous silicon carbide (a-SiC:H) thin films are deposited by using 13.56 MHz plasma enhanced chemical vapor deposition as an emitter layer for SHJ solar cells. By changing different deposition p...
Optimization of front and rear surface dielectric passivation layers for ion implanted PERC solar cells Bektaş, Gence; Canar, Hasan Hüseyin; Keçeci, Ahmet Emin; Asav, Hasan; Seyrek, Selin; Bütüner, Sümeyye Koçak; Turan, Raşit (2023-06-27) Ion implantation is an alternative doping method providing a controlled emitter profile and manufacturing simplicity for PERC solar cells. SiNx:H and SiOxNy:H layers deposited by the PECVD system are common dielectric laye...
VULNERABILITY OF ECONOMIC SECTORS TO GEOMAGNETIC STORMS AND MITIGATION STRATEGIES Demirköz, Melahat Bilge; Karagöz, G.; Kadloǧlu, Y.K.; Sözeri, H. (2023-04-21) Solar storms and CMEs increase the amount of radiation that reaches the Earth and can perturb the magnetic shielding of the Earth. K and Kp indices quantify this perturbation by using magnetometers calibrated accordingly t...
Evaluation of performance of an active terahertz imaging system for concealed face recognition Yıldırım, İhsan Ozan; Doğru, Şebnem; ŞAHİN, ASAF BEHZAT; Altan, Hakan (2023-01-01) One of the most important problems encountered by face recognition systems is occlusions. Especially with the COVID-19 pandemic, recognition of masked faces has been attracting interest. There are proposed visible spectrum...
Nanosecond Laser-Induced Micro-Modifications in Bulk of Crystal Silicon Kadan, Viktor; Pavlova, Svitlana; Bek, Alpan; Aydin, Yavuz; Blonskyi, Ivan; Pavlov, Ihor (2023-01-01) 3D modifications of crystalline Si (c-Si) by nano-, pico-, or femtosecond lasers at 1550 nm-wavelength are under intensive studies nowadays due to the wide range of potential applications in photonics and optoelectronics [...
Propagation of Laguerre-Gaussian Modes at Millimeter-wave through Scattering Media Dogru, Sebnem; Altan, Hakan; ŞAHİN, ASAF BEHZAT (2023-01-01) This work consists of the generation of free-space Laguerre-Gaussian (LG) modes at millimeter-wave frequencies by use of a 3D-printed spiral phase plate and measuring the transmission capability of LG beams with respect to...
Fast and sensitive MMW imaging system with up-conversion readout working in the NIR Zone Kurup, Arun Ramachandra; Rozban, Daniel; Kopeika, Natan S.; Yitzhaky, Yitzhak; Altan, Hakan; Abramovich, Amir (2023-01-01) Focal plane arrays (FPA) constructed using glow discharge detectors (GDD) as the pixel elements proved to be an inexpensive methodology for generating MMW (millimeter wave)/THz (terahertz) images. In the abnormal glow mode...
