| Popis: |
A 1.5 to 1.9 GeV synchrotron light sources is being built at LBL. The vacuum system is designed to permit all synchrotron photons on the median plane to escape the electron channel and go into an antechamber through a 10 mm high slot. This slot offers effective RF isolation between the electron duct and the antechamber. All unused synchrotron photons within a few mrad of the median plane will be stopped by 96 nearly horizontal absorbers located in the antechamber. The gas, generated by the photons hitting the absorbers, will be directed down to reactive titanium surfaces.Twelve 10 meter long vessels constitute the vauum chambers for all the lattice magnets. Each chamber will be machined from two thick plates of 5083‐H321 aluminum and welded at the perimeter. The nominal wall thickness of the vaccum chamber is 40 mm, which makes it possible to machine a flange into the chamber without the use of welding. |
