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. must be met. For this purpose, cavity beam dynamics studies of 1.4, 1.5, 1.6 and 1.8-cell SRF gun were performed. In addition, detailed studies have been made on the solenoid design and the location of the solenoid along the beam path. A design with the most optimized cavity geometry and RF fields for the gun cavity was posed. The injector system was designed for the Turkish SASE-FEL project with cavities of many different geometrical sizes. The most efficient high energy cavity system is determined as 1.6-cell cavity. The emittance value of the beam was achieved as 1.76 +/- 0.42 pi mm mrad and the beam energy reached at the end of cavity was obtained as 3.5 MeV.

Time resolved Fabry-Perot measurements of cavity temperature in pulsed QCLs Gundogdu, S.; Pisheh, H. S.; Demir, A.; Gunoven, M.; Aydinli, A.; Sirtori, C. (The Optical Society, 2018-3-5) Temperature rise during operation is a central concern of semiconductor lasers and especially difficult to measure during a pulsed operation. We present a technique for in situ time-resolved temperature measurement of quantum cascade lasers operating in a pulsed mode at similar to 9.25 mu m emission wavelength. Using a step-scan approach with 5 ns resolution, we measure the temporal evolution of the spectral density, observing longitudinal Fabry-Perot modes that correspond to different transverse modes.

CdZnTe Bulk Crystal Growth and Temperature Modeling Studies at METU-CGL Balbaşı, Özden Başar; DOĞRU, ÇİĞDEM; Kabukcuoglu, Merve; Ünal, Mustafa; Parlak, Mehmet; Turan, Raşit (2018-08-21) Cadmium Zinc Telluride (Cd1-xZnxTe) has become a crucial material for X-ray and gamma ray detection due to its wide band-gap, high atomic number and high density, which offer high efficiency and sharp spectroscopic resolution at room temperature. In addition, due to being lattice matched, it can also be used as substrate for the epitaxial growth of HgCdTe that can be used for infrared detection with high resolution. Hence, increasing the single crystal yield of CdZnTe from the grown ingot gained importance ...
Development of Nanocomposite Electrodes and Separators for Supercapacitors Aydınlı, Alptekin; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2022-2-10) Supercapacitors or electrochemical capacitors are known as one of the most promising energy storage systems for the 21st century. Having the potential to complement batteries, supercapacitors have received a lot of attention thanks to their high specific power and moderate energy densities. Supercapacitors have various application areas ranging from electric vehicles to portable systems and devices. In particular, their fast charge-discharge feature enables integration with consumer electronics, mobile devi...
Kinetic approach for the purification of nucleotides with magnetic separation Tural, Servet; Tural, Bilsen; Ece, Mehmet Sakir; Yetkin, Evren; Özkan, Necati (2014-11-01) The isolation of beta-nicotinamide adenine dinucleotide is of great importance since it is widely used in different scientific and technologic fields such as biofuel cells, sensor technology, and hydrogen production. In order to isolate beta-nicotinamide adenine dinucleotide, first 3-aminophenyboronic acid functionalized magnetic nanoparticles were prepared to serve as a magnetic solid support and subsequently they were used for reversible adsorption/desorption of beta-nicotinamide adenine dinucleotide in a...
Time resolved spectroscopy of laser induced air plasma Kurt, Mustafa; Esendemir, Akif; Department of Physics (2007) The laser beam interaction with matter and the plasma generation have been studied for many years. In some applications what is really important is to understand the composition and the temporal evolution of the species in the interested medium. In this thesis, time resolved optical spectroscopy was employed to understand the evolution of the plasma which is produced by interaction of Infrared (1.064 m) laser beam with air. In this thesis, a new technique is suggested to analyze the time evolution of laser ...
