	LCLS is a facility for generation of very short duration, highly intense x-ray pulses which requires an extremely reliable photocathode electron source. In order to maintain high up-time (>95%) for the experimenters, operations rely on a maintenance program for active laser components as well as on built-in redundancy in case of failure. To accomplish this, a duplicate laser system was installed, allowing for quick swap between the active system and the spare in the event of a malfunction or for planned maintenance. As an added bonus, this redundant system provides additional possibilities for science as both laser systems can also be run to the cathode simultaneously to create multiple particle bunches. Diagnostics were put in place to maintain both special and temporal overlap and allow for the fast switching between systems by operations personnel while still remaining within the safety envelope. This was done for both the primary UV drive laser as well as the secondary IR "heater" laser. This paper describes the installation challenges and design architecture for this backup laser system.

MOPGF037	Upgrades to Control Room Knobs at Slac National Accelerator Laboratory	177

	For years, accelerator operators at the SLAC National Accelerator Laboratory (SLAC) have favored hardware knobs in the control room for accelerator tuning. Hardware knobs provide a tactile, intuitive, and efficient means of adjusting devices. The evolution of separate control systems for different accelerator facilities at SLAC has resulted in multiple flavors of knob hardware and software. To improve efficiency, space usage, and ease of use, the knob systems have been upgraded and integrated.

For years, accelerator operators at the SLAC National Accelerator Laboratory (SLAC) have favored hardware knobs in the control room for accelerator tuning. Hardware knobs provide a tactile, intuitive, and efficient means of adjusting devices. The evolution of separate control systems for different accelerator facilities at SLAC has resulted in multiple flavors of knob hardware and software.
