Accepted by the Astrophysical Journal First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles and Window Functions
"... Knowledge of the beam profiles is of critical importance for interpreting data from cosmic microwave background experiments. In this paper, we present the characterization of the inflight optical response of the WMAP satellite. The main beam intensities have been mapped to ¡ −30 dB of their peak val ..."

SEE PROFILE
, 2016
"... In this work we present for the first time experimental results of measurements of spatial solitons (nematicons) in chiral nematic liquid crystalline film. We measured the propagation of light beam at the distance of a few millimeters and the nonlinear self-focusing was observed for a light power of ..."

OBSERVATION OF BETHE-BLOCH IONIZATION USING THE BOOSTER ION PROFILE MONITOR
"... The Booster Ion Profile Monitor (BIPM) was recently (April 1998) used in a test to study the feasibility of collecting the electrons instead of the more traditional ions. These electrons and ions are created by the ionization of the residual gas in the beam pipe by the proton beam. As a consistency ..."

THE OBSERVATION OF ELECTRON BEAM SIZE VARIATION BY UTILIZING THE NONLINEARITY OF A FAST PHOTODIODE
"... In the experiment study of accelerator physics, a turn by turn monitoring of the beam profile can provide very unique information. We proposed a method which may measure a turn by turn electron beam profile through its synchrotron radiation by using a fast photodiode. Here, we utilized the nonlinear ..."
