A Fast Integrated Mobility Spectrometer (FIMS) has been developed for sub-second aerosol size distribution measurements based on the description presented in the preceding paper (Paper I). The performance of FIMS was characterized using DMA classified aerosols in the size range 15–170 nm. An excellent agreement was observed between the mean particle diameter measured by FIMS and the DMA centroi...
The Main Injector Particle Production Experiment at Fermilab uses particle beams of charged pions, kaons, proton and anti-proton with beam momenta of 5 to 90 GeV/c and thin targets spanning the periodic table from (liquid) hydrogen to uranium to measure particle production cross sections in a full acceptance spectrometer with charged particle identification for particles from 0.1 to 120 GeV/c u...
Neoclassical simulations of alpha particle density profiles in high fusion power plasmas on the Tokamak Fusion Test Reactor [Phys. Plas. 5, 1577 (1998)] are found to be in good agreement with measurements of the alpha distribution function made with a sensitive active neutral particle diagnostic. The calculations are carried out in Hamiltonian magnetic coordinates with a fast, particle-followin...
Introduction: The aim of the present study was to determine the levels of alpha particles and heavy metals contamination in the meat products consumed in Najaf, Iraq. Moreover, this study was also targeted toward comparing the results with those in the literature and making appropriate conclusion and recommendations. Material and Methods: This study determined the track of alpha particles and ...
It is proposed to use a magnetic spectrometer [1,2], located behind the Super-FRS [3] in the LEB cave, for experiments with exotic beams at low and intermediate energies (5 to 200 MeV/A) and stopped beams. For the HISPEC/DESPEC [4] experiments where exotic ions are measured in coincidence with gamma spectroscopy at the secondary target MF10, a good mass identification is necessary. This require...
Strong coupling of electromagnetic cavity fields with antiferromagnetic spin waves in hematite ($\ensuremath{\alpha}$-${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$) is achieved above room temperature. A cube placed a metallic tube and the transmission measured, using continuous-wave terahertz spectrometer. The spectra, collected as function temperature, reveal formation magnetic polaritons.
