  • The short-range wakefield between two parallel conducting plates generated by a sub-relativistic beam bunch has been solved analytically by the image charge method in time domain. Comparing with the traditional modal analysis in frequency domain, this algorithm simplifies the mathematics and reveals in greater details the physics of electromagnetic field generation, propagation, reflection and causality. The calculated results have an excellent agreement with MAFIA and ABC1 simulations in all range of beam velocities.

  • Los Alamos National Laboratory (LANL) is in the process of adding Long Range Alpha Detector (LRAD) technology to its established Green Is Clean (GIC) program. GIC material includes waste and material for recycle generated in radiological controlled areas (RCAs) that have been actively segregated as ''clean'' (i.e., nonradioactive) through the use of waste generator acceptable knowledge (AK). Properly segregated GIC material has a high probability of being free of radioactive contamination. LANL GIC operations provide a verification check on the AK-based determination for low-density and certain high-density items.
  • Independent component analysis (ICA) is a powerful blind source separation (BSS) method. Compared to the typical BSS method, principal component analysis (PCA), which is the BSS foundation of the well known model independent analysis (MIA), ICA is more robust to noise, coupling, and nonlinearity. ICA of turn-by-turn beam position data has been used to measure the transverse betatron phase and amplitude functions, dispersion function, linear coupling, sextupole strength, and nonlinear beam dynamics. We apply ICA in a new way to slices along the bunch and discuss the source signals identified as betatron motion and longitudinal beam structure.
