    keyword=Scattering chamber cleaned adn we are cleared to start target switch work.

    We went in to the hall with David from Radcon. Lasers were locked out. Helium
    cooling jet turned off. Over was already lowered to room temperature. David cleaned
    (vacuumed) the scattering chamber and did swipes. After he brought the swipes back to Radcon lab and checked, he informed us that we can do the target switch work
    without Radcon coverage.
