	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules of 500-terawatt ultraviolet laser energy. The energy, temperatures and pressures capable of being generated allow scientists the ability to generate conditions similar to the center of the sun and explore physics of planetary interiors, supernovae, black holes and thermonuclear burn. NIF has transitioned to a 24x7 operational facility and in the past year significant focus has been placed on increasing the volume of experimental shots capable of being conducted so as to satisfy the demand from the wide range of user groups. The goal for the current fiscal year is a shot rate of 300 (> 50% increase over the previous year), increasing to a sustainable rate of 400 the year after. The primary focus areas to achieve these increases are; making more shot time available, improvements in experiment scheduling, and reducing the duration of a shot cycle. This paper will discuss the control system improvements implemented and planned to reduce the shot cycle duration and the systematic approaches taken to identify and prioritize them.

MOPGF099	Upgraded Control System for LHC Beam-Based Collimator Alignment	software, controls, GUI, software-architecture	306

	In the Large Hadron Collider (LHC), over 100 movable collimators are connected to a three-tier control system which moves them to the required settings throughout the operational cycle from injection to collision energy. A dedicated control system was developed to align the collimators to the beam during machine commissioning periods and hence determine operational settings for the active run. During Long Shutdown 1, the control system was upgraded to allow beam-based alignments to be performed using embedded beam position monitors in 18 newly installed collimators as well as beam loss monitors. This paper presents the new collimation controls architecture for LHC Run II along with several modifications in the Java-based application layer.
