L C L S D E S I G N S T U D Y R E P O R T Figure 14.7 Shielding and Radiationo Safety Components for the Experimental Hutches, Hall A 14.3.1 Minimum Shielding Requirements Based on the calculations that define the radiation sources the following shielding requirements have been specified: 14-12 ♦ R A D I O L O G I C A L C O N S I D E R A T G I O N S
Front End Shield: L C L S D E S I G N S T U D Y R E P O R T Lateral walls: 4.1 ft. iron plus 4.0 ft. concrete. Roof: 3.0 ft. iron plus 5.5 ft. concrete. Dump Shield: Lateral walls: 4.1 ft iron plus 4.0 ft. concrete. Front (exit) wall: 6.6 ft. iron plus 4.0 ft concrete. Back (entrance) wall: 1.6 ft. iron. Roof: 3.0 ft iron (minimum) plus 5.5 ft. concrete. Experimental Hutches Shield: Lateral walls: 2.0 ft concrete. Front and back walls: 2.0 ft concrete. Roof: 2.0 ft concrete. Local: 4 in. lead to shield down beam of the first stopper. 14.3.2 Beam Containment System SLAC’s beam containment policy requires that beam lines be designed to contain the beam, limit the incoming beam power to the beam line, and limit the beam losses to prevent excessive radiation in occupied areas [1]. The containment of the beam in its channel is achieved by implementing a system of redundant, tamper-proof, and fail-safe electronic and mechanical devices that are enforced by strict operational requirements. The BCS for the LCLS will use most, if not all, of the FFTB BCS, which is comprised of devices that limit the incoming average beam power to less than the allowed beam power (torroids of current monitors 14 and 15); devices that limit normal beam loss to 1 W (torroids 16 and 17, long ion chambers); protection collimators that ensure that errant beams do not escape containment; and devices that protect collimators, stoppers and dumps (ion chambers and flow switches). The permanent dipole magnets in the beam line that assure that the electron beam reaches the main dump are the final component of the BCS. For the LCLS, the following BCS devices will be added to the existing FFTB BCS down beam of the undulator and in the front end enclosure (Fig. 14.3). A collimator after the undulator with two ion chambers and one BTM. A collimator between the third magnet and the fourth magnet of the electron beam dump with two ion chambers and one BTM. A collimator after the last dump magnet with two ion chambers and one BTM. A beam stopper upstream of PPS stopper ST 1, which is interlocked with the x-ray intensity monitor.
