Gas Dynamics Aspects of Internal Targets

Conference paper


Based on our experience with the Indiana Cooler storage ring some aspects relevant to the design of internal polarized gas target experiments are discussed. In particular, it is pointed out that, perhaps contrary to general perception, increasing the target thickness does not necessarily lead to a proportional gain in luminosity: In our studies with cooled beams of 100 to 200 MeV, interacting with internal H2 targets, the luminosity as a function of target thickness shows a broad maximum in the range of 1014 to 1015 atoms/cm2.
