  1. Design Study For The Storage Ring of Turkish Light Source Zafer Nergiz NigdeUniversity

  2. Introduction • The goals of the storage ring suggested after LSUM-2012 (Light Source User Meeting) • 3 GeV electron beam energy • Low emittance; below 1 nm rad • Short circumference; below 500 m • A new ring is designed according to the suggestions in user meeting • Linear and nonlinear effects are investigated • The radiation properties are investigated. • Effects of theundulatorstothebeamdynamic is investigated.

  3. Layout of theLightsource The machine consist of mainly three part: Injector, booster ring and storage ring. The radiation properties are strongly depend on the storage ring parameters. Booster and Storage ring is designed. Zafer Nergiz| NigdeUniversity

  4. Storage Ring • The storage ring is composed with 20 main cells • Main cell consists of 4 bending magnets and 4 different type 16 quadrupol magnets. • The circumference is 477 m • Natural horizontal emittance is 0.51 nm rad. • The number of straight section is 20 Zafer Nergiz | NigdeUniversity

  5. BeamParameters The working point is chosen where the third order resonance driving terms and tune shifts are as small as possible. 7families of sextupol are used to correct chromaticity and to compensate nonlinearities. The length of straight sections is 5 m. The bending magnets are 1.5m length and the magnetic field in the bending magnets is 0.52 T. Theadvantage is lowrfpowerrequirment.

  8. Nonlinear Beam Dynamics: Tracking According to MADX simulation the shape deformation of phase ellipse start x=1.2cm and y=1 cm Phase space tracking in the horizontal and vertical plane at the center of straight section (1000turn) Zafer Nergiz | Nigde University

  9. Nonlinear Beam Dynamics: Dynamic aperture The dynamic aperture is the stable transverse area for the particle safely without getting defused or lost. a) Dynamical aperture for different momentum offset without magnet error (%3, %0 , %-3) b) Effects of magnet errors to the dynamical aperture (1024 turn) Zafer Nergiz | Nigde University

  10. NonlinearBeam Dynamics: FMA Frequency Map Analysis (FMA) is a numerical method which is a possible way to understand the effect of resonance to the dynamic aperture. Diffusion rate of frequency map analyses from tracking results. (the colors are for log10(Dnx+Dny)) (1024 turn). Zafer Nergiz| Nigde University

  15. Conclusions Low emittance storage ring is designed. It is reached to 0.51 nm rademittance with 477 m ring circumference Nonlinear effects arealso investigated. Effects of the ID’s to the beam are acceptable values. It is planned to complete the machine report including main sub-systems up to mid of next year in parallel to the scientific case report.
