DIRECT DETERMINATION OF THE WEAK CHARGE OF THE PROTON VIA PARITY-VIOLATING ELECTRON SCATTERING
… News, VA. A longitudinally polarized electron beam was scattered by a liquid hydrogen target. The spin direction of the electron beam was switched between left and right helicity states. The cross section under both of the electron states were measured to form the parity-violating asymmetry. An …

Measurements and characterization of intra-fractional prostate motion during SBRT treatment of prostate cancer on cyberknife for optimizing image-guided dose delivery
… movements of translations and rotations, the beams can be corrected before beam-on dose delivery. For larger magnitudes of prostate movements that exceed the limits of beam corrections, treatment was automatically halted to allow re-establishing the target alignment before resuming the …

Development and optimization of reconfigurable planar lenses and reflectors
… reflectarray was fabricated, obtaining beam steering from −10º to 30º in azimuth and from −20º to 20º in elevation. In the array lens, communicating the input and output layers in the guided-wave approach requires extra layers, more complex structures or increased element spacing. This …
