METU-Defocusing beam line project and beam optics studies

2017-07-31
METU-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, nuclear and medical applications. Turkish Atomic Energy Authority (TAEA) has a 30MeV proton cyclotron at Proton Accelerator Facility (PAF) mainly for radioisotope production and an R&D room for other applications. The proton beam current is variable between 0.1µA to 1.2mA and the beam size is small. METU-DBL, which is being installed in the R&D room, will enlarge the beam size with three quadrupole magnets and reduce the proton flux with scattering foils and collimators in order to have a suitable irradiation area according to ESA ESCC No. 25100 standard. The beam optics studies and particle tracking studies have been performed and will be presented here. Also, the beam parameters have been measured with a beam viewer in the R&D room and the results will be reported. Construction of the METU-DBL preliminary test setup, with two quadrupole magnets, a collimator and a long flight path to allow the beam to blow up, as well as supporting sub-systems, has been completed and the first tests will be performed in October 2017.

Performing The First Single Event Effect Tests using The METU Defocusing Beamline Project
Demirköz, Melahat Bilge (2018-12-27)
METU-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, nuclear and other applications. Turkish Atomic Energy Authority (TAEA) has a cyclotron which can accelerate protons up to 30 MeV kinetic energy at the Proton Accelerator Facility (PAF) mainly for radioisotope production and for research and development (R&D) purposes. In the facility, the stable proton beam current is variable between 0.1 µA to 1.2 mA and the beam size is nearly 1 cm x 1 cm. METU-DBL pre-...
Terahertz (>0.3THz) active imaging systems
İdikut, Fırat; Altan, Hakan; Department of Physics (2016)
Imaging systems based on terahertz waves are becoming an integral part of commercial and military screening applications. In this thesis, the prototype of active scan THz imaging system was constructed for detection of concealed objects at standoff distance longer than 5m. The system was mounted on a platform that can adjust in height, tilt and azimuthal angle. The methods of generation and detection of THz signal are based on Schottky diode rectifiers and Schottky diode mixers. The wavelength of the contin...
Quantum Transport Mode in Graphene Nanoribbon Based Transistor
Hedayat, Sayed Norollah; Ahmadi, Mohammad Taghi; Sedghi, Hassan; Goudarzi, Hadi; Moradi, Shahram (American Scientific Publishers, 2017-09-01)
Graphene has incredible carrier transport property with high application opportunity at single molecule level, which composes it as promising materials on nano electronic application. In order to develop the new device such as graphene nanoribbon transistor, Carbon Nanotube Field Effect Transistor (CNTFET) and nanowire based devices, it is essential to investigate the quantum limit in low dimensional systems. In this paper transmission coefficient of the schottky structure in the graphene based transistor i...
Computational analysis of a solar vortex
Mohiuddin, Abdullah; Uzgören, Eray; Sustainable Environment and Energy Systems (2015-3)
This thesis investigates power generation opportunities by considering computational analysis of an experimental setup which is initially proposed to mimic dust devils in a controlled environment. The concept relies on buoyancy effect over a heated plate surrounded by vertical thin plates or vanes. Once the heated air starts rising, vertical vanes help surrounding air to flow inwards in a direction tangential to the vortex core to introduce swirl to the flow. Present study focuses on the computational fluid...
