Opis:: We present the preliminary results on direct photon interferometry measurements in Au+Au collisions at square root sNN = 62.4 GeV and 200 GeV using the STAR (solenoidal tracker at RHIC) detector. Photons are reconstructed via e+/e- conversions in STAR Time Projection Chamber (TPC) and energy deposited by photons in STAR Barrel Electromagnetic Calorimeter (BEMC). The two-photon correlations are measured using (1) both photons measured with BEMC; (2) one photon from conversions and the other measured with BEMC. Both the methodologies and the possible constraints in the correlation function measurements are discussed.

Opis:: Repeated magnetic flux surface measurements confirmed the existence of closed and nested flux surfaces, but also revealed the existence of magnetic error fields. The simultaneous application of two radio frequency systems for plasma heating operating at 28 GHz and 2.45 GHz, respectively, allowed to reach otherwise non-accessible plasma regimes in WEGA due to synergetic effects. These regimes are characterized by over-dense plasmas at 0.5 T operation by means of electron Bernstein wave heating and the existence of supra-thermal electrons associated with soft X-ray and gamma-rays. The thermal electron diffusion coefficient was determined in the electron Bernstein wave heated plasma regime. Additionally, results from turbulence studies in low density plasmas in the vicinity of magnetic islands are presented.

Opis:: Abstract A hydrodynamics + hadronic rescattering model is used to simulate Au+Au collisions at 200 GeV and a Cooper-Frye method is adopted for hadronization. The effect of hadronic rescattering on elliptic flow V2 in 20 40% Au+Au collisions at 200 GeV has been investigated. It is found that the hadronic rescattering can suppress elliptic flow V2 and makes an asymmetric system in momentum space tend to be less anisotropic. The suppression effect becomes weak with increasing transverse momentum. In addition, the effect of hadronic rescattering on transverse momentum spectra and anisotropy of hadronic coordinate space is presented.
