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. …”

Automated Engineering Design for Reusable Concrete Building Structures by Wongsittikan, Pitipat

“…The Pixelframe structural system [1] was proposed to facilitate the reusability of concrete components by implementing the existing external post-tensioning system in bridge structures and fiber reinforced system to design building beams and columns. This work presents an automated engineering design workflow for Pixelframe, including a engineering mechanics of the system that conforms to ACI 318- 19 [2] and fib Model Code 2010 [3], half-scale tests to verify the preliminary behavior of the system, and a scalable design algorithm for minimum embodied carbon designs. …”
