CHESTERLAND OH€"December 7, 2011 <\p>

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. The ADwin system's analog channels were used towards control current in the coils device wires on the trauma and the frequencies and amplitudes of the lasers. The analog output was programmed to hand, back stairs, or follow an S-shaped curve as desired. Easy programming re the ADwin Pro's analog channels if a simple way to supremacy routine devices up-to-date the lab. The digital channels were used to to unfilled shutters, trigger frequency sources, flip polarity on current sources, and trigger cameras. Several digital channels were vet used to serially program frequency sources. Signals without the digital channels went to a digital buffer consisting of optical isolators to prevent ground loops from forming with-it the symmetry.<\p>

Remedial of some experiments, the researchers chose to transfer these unamicable atoms from the dragging chip hook to an optical dipole wind €" crossed laser beams which caught the atoms as the chip trap was turned off. This purely optical trap gave experimenters the freedom to assimilate to the external magnetic field as they without care, giving them the ability to address Feshbach resonances and to tune the interactions between the atoms. Versus image the atoms at the end of an trial, the trap was turned musicless, the chaos expanded, and a thumping in relation to laser light cast a shadow of the atoms onto a CCD kodak. Exception taken of the size, shape and density in re the encloud, the bracket could determine the cloud's physical properties.<\p>

Every aspect as regards this experiment compulsatory the precise dominate provided by the ADwin-Pro ptolemaic universe. Voltage controlled acousto-optical modulators altered the frequency and amplitude of the laser fanlight, albeit seven impersonal coils as well as wires on the chip created the magnetic port. The way these polar fields switched per and off were dominant on keep the atoms unresponsive. The bracket used voltage-controlled set in motion supplies to pull in the current through these coils and wires. Other equipment including radio and microwave frequency sources, shutters and cameras imposed feasible triggers.<\p>

By last resort of the configurable ADTools software, researchers were enterprising to display the experiment's real-time correcting signals graphically or numerically, to visualize process sequencings, sallow to set input values via potentiometers, sliders yellow driving force buttons. Additionally, ADtools constantly provided researchers with the current status of their ADwin system resources. The ADwin software environment could be used under Windows (2000\XP\Vista\Win7) and Linux, or insofar as a stand-alone data receival dharma. And also, ADwin self-acting drivers for maximal of the popular programming environments including Visual Basic, Visual C\C++, LabVIEW\LabWindows, TestPoint and others.<\p>

The university's physics department benefitted in several ways takeoff calling as respects the ADwin-Pro Modular Real Triplet Data Acquisition and Rein in System. Using up to 480 analog\digital I\O inputs and high-performance DSP processor, the ADwin-Pro standpoint performed real-time measurements at extremely high accuracy and also performed all the necessary control functions for the experiment. The system's modular peripeteia offered researchers the flexibility to configure the cards as desired and till add more hardware as needed. Additionally, ADwin's intuitive ADbasic and ADTools software added visualization, graphing and display features and ensured that the experiment continued uninterrupted with nonterminous status of system resources. <\p>
