Our weapons, our problem: arms exports, democracy and civil society in Brazil and the UK by de Moraes, RF

“…The causal mechanism is in part explained by activities conducted by norm entrepreneurs, whose emergence is facilitated by the existence of institutions commonly found in democratic countries, especially a system of checks and balances, contested elections, and political and civil liberties. …”

Compact x-ray source based on burst-mode inverse Compton scattering at 100 kHz by Bessuille, J., Brown, P., Carbajo, S., Dolgashev, Valery A., Lin, H., Murari, K., Resta, G., Tantawi, S., Zapata, L. E., Graves, William S., Hong, Kyung-Han, Ihloff, Ernest E., Khaykovich, Boris, Nanni, Emilio Alessandro, Kaertner, Franz X., Moncton, David E.

“…At a photon energy of 12.4 keV, the predicted x-ray flux is 5×10[superscript 11]  photons/second in a 5% bandwidth and the brilliance is 2 × 10[superscript 12]  photons/(sec mm[superscript 2] mrad[superscript 2]  0.1%) in pulses with rms pulse length of 490 fs. The nominal electron beam parameters are 18 MeV kinetic energy, 10 microamp average current, 0.5 microsecond macropulse length, resulting in average electron beam power of 180 W. …”
