Conditions Around the Proton Beam Window of the Spallation Neutron Source
- ORNL
A proton beam window separates regions with different vacuum conditions in the last part of the path of the proton beam. Very near to the window an instrumentation box for beam diagnostics is going to be located. All components comprising the proton beam window assembly are going to be located in a box, which has to be serviced regularly through a channel perpendicular to the direction of the beam (2mA 1 GeV protons). Due to the strong effects of the proton window, the engineering design of this part of the target facility requires detailed calculations of the heating and dose distributions for beam on and off conditions as a function of the materials for the window and the shielding of the instrumentation box. A summary of the results, relevant to decisions to be taken regarding the design and operation of the facility, are presented.
