Radiation Protection Aspects in the Design of the Linac Coherent Light Source II
Santana, Mario.
Since 2009, the Linac Coherent Light Source at the SLAC National Accelerator Laboratory produces ultra-fast, ultra-bright X-ray pulses with which atoms and molecules can be visualized as they move, hence revealing the mechanics of chemistry and revolutionizing the research in fields ranging from biology to energy sciences. LCLS-II is a sister vicinal facility with new features that will be soon constructed to address the surging demand of FEL beams. In this paper we summarize the radiatio... Show Full Abstract
Since 2009, the Linac Coherent Light Source at the SLAC National Accelerator Laboratory produces ultra-fast, ultra-bright X-ray pulses with which atoms and molecules can be visualized as they move, hence revealing the mechanics of chemistry and revolutionizing the research in fields ranging from biology to energy sciences. LCLS-II is a sister vicinal facility with new features that will be soon constructed to address the surging demand of FEL beams. In this paper we summarize the radiation protection scheme for LCLS-II and we describe diverse challenges and the adopted solutions. In particular we present the access modes of LCLS-II that allow simultaneous operation with LCLS. Monte Carlo simulations have been used to design beam components like stoppers and to define the thickness of walls. Also, by carefully analyzing the contributors to the residual dose, the shielding of the main dumps has been optimized to meet engineering constraints while allowing access after short cool down.
