Using the ORBIT code we study the sensitivity of electron cloud properties with respect to different proton beam profiles, the secondary electron yield (SEY) parameter, and the proton loss rate. Our model uses a cold proton bunch to generate primary

We present experimental data from the Los Alamos Proton Storage Ring (PSR) showing long-lived linac microbunch structure during beam storage with no rf bunching. Analysis of the experimental data and particle-in-cell simulations of the experiments in

We present studies of space-charge-induced beam profile broadening at high intensities in the Proton Storage Ring (PSR) at Los Alamos National Laboratory. We investigate the profile broadening through detailed particle-in-cell simulations of several

Fermilab is working on the design of an 8 GeV superconducting RF H-linac called the Proton Driver. The energy of H-beam will be an order of magnitude higher than the existing ones. This brings up a number of technical challenges to transport and inje

The energy gain and motion of electrons can quantitatively describe the mechanism of electron multipacting in a long-bunched proton machine. Strong multipacting usually happens around the bunches' tails due to the high energy of electrons when they h

Constitutive activation of Ras or Ras-mediated signaling pathways is one of the initial steps during tumorigenesis that promotes neoplastic transformation. Recently it was reported that in Ha-Ras overexpressing MDCK cells the tight junction proteins

Electron cloud is still an unsettled issue for the high intensity SNS storage ring. Studies are undergoing, especially on the electron multipacting condition, beam instability threshold, electron density and the electron dose on the wall. It has been

Monte Carlo simulations of 800-MeV proton beam spills in common shielding materials show that neutron dose equivalent rates in the forward direction can be characterized by a Moyer Model-like formula. Particle transport codes were used to determine t
