Experimental High Energy Physics Summer School For High Schools

Experimental High Energy Physics Summer School for High Schools, (Liseler \.{I}\c{c}in Deneysel Y\"{u}ksek Enerji Fizi\u{g}i Yaz Okulu - lidyef2018) was held between 9-16 September 2018 at Bo\u{g}azi\c{c}i University, Turkey, with financial support from T\"{U}B\.{I}TAK under the 4004 grant 118B491. Out of nearly 700 (11th and 12th grade) applicants, 30 had been selected from all around Turkey. Students were introduced to the fundamentals of high energy physics and performed experiments that demonstrated the techniques of this field, such as a salad-bowl electrostatic accelerator, and a cloud chamber. Here we report on the planning, implementation and the outcomes of the school that can serve as a template for similar activities in the future.Comment: 9 pages, 10 figures, TFD 34 conference proceedin

Beam Diagnostics for Low Energy Proton Beam

An 800 MHz Radio Frequency Quadrupole (RFQ) is being designed for obtaining 2MeV protons at KAHVELab. The beam originating from the ion source has to match the RFQ via an optimised Low Energy Beam Transport (LEBT) line. LEBT line consists of two solenoids, a beam diagnostic box in between, and two steerers. The solenoids will be utilised to focus the divergent beam coming from the microwave discharge ion source to the RFQ.The steerers will be deployed to direct the beam into the RFQ. The diagnostics are aimed to measure the proton beam’s current, profile as well as the beam emittance upstream of the RFQ. The measurement box is designed and ready for production. The prototype for the Faraday cup is produced, for the scintillator screen will be home-built, and for the pepper pot plate is being manufactured. In this talk, the magnetic field measurements of the steerers, the electromagnetic simulation and the assembly of the FC and design code of the emittance measurement will be presented.This study is supported by TUBITAK Project no: 119M77

Monitoring Akkuyu nuclear reactor using antineutrino flux measurement

We present a simulation-based study for monitoring Akkuyu nuclear power plant's activity using antineutrino flux originating from the reactor core. A gadolinium-doped water Cherenkov detector was designed and optimization studies were performed using the Geant4 simulation toolkit. It was found that the bottom (or top) face of the target should be instrumented by six 10-inch-diameter photomultiplier tubes with photon detection efficiency of about 35% and the optimum Gd concentration was found to be about 0.3%-0.5%. The first study on the design of a monitoring detector facility for Akkuyu nuclear power plant is discussed in this paper

A meta-analysis of LHC results

We report the preliminary results of a meta-analysis conducted to examine possible biases in the uncertainty values published in papers by ATLAS and CMS experiments. We have performed this analysis using two independent techniques; a vectoral analysis of the vector graphics files and a bitmap analysis of the raster graphic files of the exclusion plots from various physics searches. In both procedures, the aim is to compute the percentages of the data points scattered within 1-sigma and 2-sigma bands of the plots and verify whether the measured percentages agree with statistical norms assuming unbiased estimations of the uncertainties.We report the preliminary results of a meta-analysis conducted to examine possible biases in the uncertainty values published in papers by ATLAS and CMS experiments.

Design, Simulation And Construction Of A Delay Wire Chamber

Delay wire chamber (DWC) is a relatively inexpensive gaseous detector that enables tracking of charged particles with high resolution. Here, design and simulation of a DWC that is suitable for beam diagnostics measurements at low-energy accelerators are described. We report on the mechanical construction of such a chamber at the Kandilli Detector, Accelerator and Instrumentation Laboratory, and the tests performed with cosmic muons and radioactive sources
