Test particle motion is analyzed for a matched intense charged-particle beam in a periodic focusing solenoidal magnetic field to assess the effects of beam intensity on inducing chaotic particle motion and halo formation.

The trapping of dust particles has been observed in a dc abnormal glow discharge dominated by electron attachment. A dust cloud of several tens of positively charged particles was found to form in the anode sheath region. An analysis of the experimental conditions revealed that these particles were positively charged due to emission process, in contrast to most other experiments on the levitati...
We developed an efficient synthesis of monodisperse, highly surface charged, high refractive index ZnS spherical particles by using a gel-sol method. Concentrated solutions of zinc-ammonia-NTA (nitrilotriacetic acid) were reacted with thioacetamide in the presence of gelatin which stabilized the growing particles. We dramatically increased the particle surface charge density by condensing silic...
Multiplicities of intermediate-mass fragments (IMFs), neutrons, and charged particles were measured for 112Sn 1 112Sn and 124Sn 1 124Sn at EyA 40 MeV. Significantly different scalings of the mean IMF multiplicities with neutron and charged-particle multiplicities are observed for the two reactions. These differences can be qualitatively understood in terms of fragment emission from an expandi...

Results on two-particle angular correlations for charged particles produced in pp collisions at a center-of-mass energy of 13 TeV are presented. The data were taken with the CMS detector at the LHC and correspond to an integrated luminosity of about 270 nb^{-1}. The correlations are studied over a broad range of pseudorapidity (|η|<2.4) and over the full azimuth (ϕ) as a function of charged pa...
Thir report presents a study made of the DSN charged particle calibration requirements. The ejyects of charged particles on navigation and timing systems were reviewed and it was prcposed that a system based upon the Global Positioning System satellites be used to measure the charged particle content of the ionosphere. The system would be required to measure the total electron content of the io...
We study the effect of chirp on electromagnetic (EM) pulse interaction with a charged particle. Both the one-dimensional (1D) and 3D cases are considered. It is found that, in contrast to the case of a nonchirped pulse, the charged particle energy can be changed after the interaction with a 1D EM chirped pulse. Different types of chirp and pulse envelopes are considered. In the case of small ch...
