	The linear accelerator complex at the SLAC National Accelerator Laboratory has been upgraded to include LCLS-II, a new linac capable of producing beam power as high as several hundred kW with CW beam rates up to 1 MHz while maintaining existing capabilities from the copper machine. Because of these high-power beams, a new Machine Protection System with a latency of less than 100 us was designed and installed to prevent damage to the machine when a fault or beam loss is detected. The new LCLS-II MPS must work in parallel with the existing MPS from the respective sources all the way through the user hutches to provide a mechanism to reduce the beam rate or shut down operation in a beamline without impacting the neighboring beamline when a fault condition is detected. Because either beamline can use either accelerator as its source and each accelerator has different operating requirements, great care was taken in the overall system design to ensure the necessary operation can be achieved with a seamless experience for the accelerator operators. The overall system design of the LCLS-II MPS software including the ability to interact with the existing systems and the tools developed for the control room to provide the user operation experience will be described.

The linear accelerator complex at the SLAC National Accelerator Laboratory has been upgraded to include LCLS-II, a new linac capable of producing beam power as high as several hundred kW with CW beam rates up to 1 MHz while maintaining existing capabilities from the copper machine. Because of these high-power beams, a new Machine Protection System with a latency of less than 100 us was designed and installed to prevent damage to the machine when a fault or beam loss is detected. The new LCLS-II MPS must work in parallel with the existing MPS from the respective sources all the way through the user hutches to provide a mechanism to reduce the beam rate or shut down operation in a beamline without impacting the neighboring beamline when a fault condition is detected. Because either beamline can use either accelerator as its source and each accelerator has different operating requirements, great care was taken in the overall system design to ensure the necessary operation can be achieved with a seamless experience for the accelerator operators. The overall system design of the LCLS-II MPS software including the ability to interact with the existing systems and the tools developed for the control room to provide the user operation experience will be described.
