Hi all, I have added a short discussion about so-called "Tube tails" into the BGMN site. Please see http://www.bgmn.de/device.html#tubetails I cite from this site: >Since the time of our first usage of fundamental parameters profile model, >our measurements are disturbed by so-called "tube tails". Tube tails mean: >A small part of the X-rays emitted by the tube originates not inside the >focus, but up to 1...2cm sideways of the focus. This means 1...2mm equitorial >broadening towards both sides of the optical focus. This tube tails may >totally disturb the profile shapes calculated by fundamental parameters. If someone has experience with those tube tails, too: Please told us. Maybe, tube tails will be discussed in this mailing list. Sincerely Yours J. Bergmann
