	CODAG2 \| Space Tech.
		The main part of the CODAG experiment consists of a specially-designed vacuum chamber into which a homogeneous dust cloud is injected via two different dust dispersers.
		The third scientific instrument onboard CODAG is designed to study the optical properties of the growing dust clusters.

	CODAG - Results II (Site not responding. Last check: 2007-10-15)
		The unexpected chain-like structures of the dust aggregates, which were formed in the CODAG experiments, might be caused by the hitherto neglected Brownian rotation of the dust grains during their collisions.
		In a microgravity experiment during the Maser 8 sounding rocket flight, we observed this rotation with high spatial and high temporal resolution.
		The normalized, cumulative mass spectra of the CODAG dust aggregates for four different times.

	CODAG \| Space Technology
		CODAG will be carried out to simulate the process of dust aggregation due to pure Brownian motion of the grains, a process which theoreticians believe to be the "igniter" of the subsequent agglomeration steps.
		The parameters of the ten single experiments which will be performed by CODAG were chosen to yield basic knowledge about the physics of the aggregation in a regime relevant for astrophysics.
		Among the questions scientists hope to answer with the results of the CODAG experiments, the most prominent are how fast the agglomeration process is in reality and what the inner structures of the agglomerates are.

	CODAG: watching dust gather (September 2000) - News - PhysicsWeb
		The CODAG experiment recreated for the first time conditions in the early solar system in order to observe the dust clustering process.
		This scenario is likely to be similar to conditions in the early solar environment, in which the dust and gas nebula would have provided a shield from the ionising effects of solar radiation.
		However, the CODAG experiment did not take into account magnetic field effects, and experiments are now being devised to establish the possible role of magnetic forces in the aggregation process.

		The Cosmic Dust Aggregation Experiment (CODAG), an experimental simulation of the onset of planet formation, was successfully flown on STS-95 (October/November 1998) and on Maser 8 (May 1999).
		The main objective of the CODAG experiment was a direct observation of the Brownian motion-induced coagulation process of micron-sized dust particles.
		To overcome rapid sedimentation of the dust grains in the rarefied gas atmosphere, experiments were conducted in a long-duration microgravity environment.

	The cosmic dust aggregation experiment CODAG
		With CODAG, we intend to study the aggregational behaviour of a cloud of micron-sized dust particles due to Brownian motion of the grains.
		For a realistic simulation of the processes in the young solar system, the dust grains have to be dispersed in a rarefied gas so that mutual collisions are ballistic.
		In this paper, we present an overview of the experimental design of CODAG which was recently flown in a Get Away Special container during the STS-95 mission.

	MAN Diesel - PRESS->PRESS RELEASES->TURBOCHARGERS
		“When either the TCS-PTG or CODAG solution is used in combination with an MAN Diesel high efficiency turbocharger on the main engine, additional electrical power equivalent to 3% to 5% of main engine power can be recovered.
		The power turbine of the TCS-PTG system is connected to a gearbox, which reduces its output speed to the synchronous speed required by the TCS-PTG system generator to produce 50 Hz or 60 Hz electrical power.
		The MAN Diesel CODAG system, on the other hand, is designed to be integrated onto a diesel generator set.
