B Why target is putting rotated on DDX experiment?

  1. Nov 28, 2016 #1
    Hello. I have a question about DDX (double-differential cross-sections) experiment.
    On DDX experiment, people are putting the target rotated about 45 degree.
    I wonder why they put the target rotated and what benefit exist because of that.
    Thank you

    Cross-section of what, in which range, with which target?

    If the incident particles are low-energetic: a larger range of phase space where the produced particles don't have to go through other material?

    If there are detectors placed at forward and back angles, you place the targets rotated at 45 degrees to minimise energy loss and to ensure that the target frame does not shadow the forward detector. It basically depends on the setup. Can you post a link to the paper?
