Very intense neutrino beams and large detectors will be needed in order to enable the discovery of CP violation leptonic sector. We propose use proton linac European Spallation Source currently under construction Lund, Sweden deliver, parallel with spallation neutron production, a very intense, cost effective high performance beam. The baseline program for is that it fully operational at 5 MW average power by 2022, producing 2 GeV 2.86 ms long pulses rate 14 Hz. Our proposal upgrade 10 28...
Abstract Objectives Hyams proposed a histological grading system for esthesioneuroblastoma in which grade I tumors have an excellent prognosis and IV are uniformly fatal. The predated advanced craniofacial techniques, extensive use of immunohistochemistry, the recognition sinonasal undifferentiated carcinoma (SNUC) as distinct entity. Therefore we aimed to determine whether classification is useful predicting outcome SNUC. Study Design A retrospective review cases from 1970 1999. Methods...
The LHC is currently operating with a proton energy of 4 TeV and ${\ensuremath{\beta}}^{*}$ functions at the ATLAS CMS interaction points 0.6 m. This close to design value 7 (${\ensuremath{\beta}}^{*}=0.55\text{ }\text{ }\mathrm{m}$) represented challenge for various aspects machine operation. In particular, huge effort was put into optics commissioning an unprecedented peak $\ensuremath{\beta}$ beating around 7% achieved in high hadron collider.
Optics stability during all phases of operation is crucial for the LHC. Tools and procedures have been developed rapid checks beta beating, dispersion, linear coupling, as well prompt optics corrections. Important errors different beam commissioning were observed locally corrected using segment-by-segment technique. The most relevant corrections at injection corroborated with dedicated magnetic measurements.
The European Spallation Source (ESS), currently under construction in Lund, Sweden, is a research center that will provide, by 2023, the world’s most powerful neutron source. average power of proton linac be 5 MW. Pulsing this at higher frequency make it possible to raise total beam 10 MW produce, parallel with spallation production, very intense neutrino Super Beam about 0.4 GeV mean energy. This allow searching for leptonic CP violation second oscillation maximum where sensitivity 3 times...
An AC dipole is a magnet which produces sinusoidally oscillating field and excites coherent transverse beam oscillations in synchrotron. By observing this driven oscillation, the linear optical parameters can be directly measured at locations of position monitors. The induced by an will generate phase space ellipse differs from that free oscillations. If not properly accounted for, difference lead to misinterpretations actual parameters, for instance, 6% or more cases Tevatron, RHIC, LHC....
The European Spallation Source, ESS, uses a linear accelerator to bombard the tungsten target with high intensity protons beam for producing intense beams of neutrons. nominal average power linac is 5 MW peak at 125 MW. During last year ESS cost was re-evaluated, and meet budget few modifications were introduced design. One major changes reduction final energy from 2.5 GeV 2.0 therefore current increased accordingly compensate lower energy. As result designed objective by taking higher risk....

Radio-on-fiber (ROF) access systems have been studied as an excellent approach for future DSRC (dedicated short range communications) infrastructure in ITS. The paper addresses the system utilizing radio-on-fiber technique with possibility of soft hand-over or zone-diversity between adjacent radio zones by centralized control. A reduction method is proposed to compensate intermodulation distortion (IMD) due nonlinearity E/O converters and RF amplifiers. IMD improvement about 20-25 dB can be...
