Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit

R. Wesselink1
1Demcon Multiphysics, Enschede, The Netherlands

When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... Per saperne di più

Design and Simulation of an Additive Manufactured Microwave Cavity for Compact Cold Atom Clocks

C. Affolderbach1, E. Batori1, G. Mileti1
1University of Neuchâtel, Neuchâtel, Switzerland

We present the design and performance simulations for a microwave cavity for use in novel compact cold atom atomic clocks. Design goals for such a microwave cavity are a resonance frequency at the Rubidium ground-state transition frequency of 6.835 GHz, combined with a moderate quality ... Per saperne di più
