Present and next generation of long-baseline accelerator experiments are bringing the measurement neutrino oscillations into precision era with ever-increasing statistics.One most challenging aspects achieving such measurements is developing relevant systematic uncertainties in modeling nuclear effects neutrino-nucleus interactions.To address this problem, state-of-the-art detectors being developed to extract detailed information about all particles produced fully profit from these...
The impact of reactive ion etching (RIE) induced damage on the optoelectronic properties GaN epitaxial layers and photoresponse Schottky detectors is investigated. Plasma surface in noticed which leads to a significant reduction intensity photoluminescence signal also detector devices post dry process. Electrical characterization Au/Ni/GaN diodes along with secondary mass spectroscopy results indicate that bombardment mostly confined close layer. It found current-voltage characteristics...
The performance of superconducting radio frequency (SRF) cavities is strongly influenced by various impurities within the penetration depth (~50 nm) niobium (Nb), which in turn depends on applied surface treatments. effect these treatments Nb has been explored using analytical techniques. However, results are still inadequate many aspects and sequential SRF impurity distribution not explored. present study analyzes samples, treated cavity processing techniques such as colloidal silica...

The oblate spheroidal shape is close to the commonly used elliptical rf cavity employed in accelerators. Here we solve radial and angular wave functions obtain frequencies of axisymmetric TM TE modes. We develop a semianalytic formalism calculate characteristic parameters, such as shunt impedance, higher order modes (HOMs). Our formulation applied HOM INDUS-2 ILC cavities, agreement with three-dimensional finite element calculations excellent. Using this investigate effect changing shape,...
