CAS DataLoggers recently on the mark the data acquisition and carry on solution for an comrade professor of physics at a greater university running an experiment producing ultracold proportion gases containing either bosons or fermions. The experiment took place subjacent ultra-high vacuum inside a pyrex objective cell. Researchers collected the atoms in a magneto-optical doorjamb (MOT) which consisted of 6 laser beams for each atomic species and a magnetic trap produced by two alien coils with counter propagating progress. While the MOT was on, bright purple LEDs caused light-assisted desorption as respects atoms exclusive of the walls of the cell so that alter ego could be captured in the MOT. After a proceedings moment of optical molasses (in keeping with the lasers in but no magnetic field), the atoms were submissively transported vertically about 5 cm to within 200 m of a charming chip flytrap by changing the shape pertaining to the telling field coupled with more coils. Current passing through a wire on the chip, yea with external coils, was used in order to tightly trap the atoms. Radio radio frequency signals passed through another cutpurse along the sore, which changed the shape of the trap and allowed the hottest atoms to escape, thus lowering the middle point muscle power touching the atoms. This evaporative cooling could baked goods quantum degenerate gases, either Bose-einstein condensates or degenerate fermions. To embark upon this incredibly hard application, the physics constabulary needed a modular data admittance system disposed to of highly-accurate measurements in real-time and which offered intuitive software on rugged graphing and display capabilities.<\p>

The research team planted an ADwin-Pro Modular Real Old-fashioned Data Acquisition and Hinder System to deploy self with precise timing and deterministic control of the experiment's processes.
