Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension eliminates the gravitational sag for trapped atoms. These advantages motivated numerous initiatives to adapt operate experimental setups microgravity platforms. We describe design payload, motivations choices, capabilities Bose-Einstein Condensate Cold Atom Laboratory (BECCAL), a NASA-DLR collaboration. BECCAL builds heritage...
A Residue Number System (RNS) represents integers through a set of residues obtained by integer division using predefined pairwise coprime moduli. RNS is well-known for enabling efficient carry-free arithmetic and representing large numbers with multiple shorter numerical values. By incorporating additional moduli, the system can be extended into an over-determined Redundant (RRNS), introducing redundancy that facilitates detection correction bit errors.

Abstract Custom experiment setups in physics often require control electronics to execute actions and measurements on a small time scale. When further constraints limit the experiment's environment, for example when is inside sounding rocket, conventional network systems will not suffice those because of weight, heat or budget limitations. This paper proposes architecture with resolution less than 1 ns over pair plastic fibers while using low-cost commercial hardware. The comparison copper...
Field-programmable gate arrays (FPGAs) in space applications come with the drawback of radiation effects, which inevitably will occur devices small process size. This also applies to electronics Bose Einstein Condensate and Cold Atom Laboratory (BECCAL) apparatus, is planned operate on International Space Station for several years. A total more than 100 FPGAs distributed setup be used high-precision control specialized sensors actuators at nanosecond scale. Due large amount BECCAL,...
