	The LINAC Coherent Light Source II (LCLS-II) is an upgrade of the SLAC National Accelerator Laboratory LCLS facility to a superconducting LINAC with multiple destinations at different power levels. The challenge in delivering timing to a superconducting LINAC is dictated by the stability requirements for the beam power and the 1MHz rate. A timing generator will produce patterns instead of events because of the large number of event codes required. The poster explains how the stability requirements are addressed by the design of two Graphical User Interfaces (GUI). The Allow Table GUI filters the timing pattern requests respecting the Machine Protection System (MPS) defined Power Class and the electron beam dump capacities. The Timing Pattern Generator (TPG) programs Sequence Engines to deliver the beam rate configuration requested by the user. The low level program, The TPG generates the patterns, which contains the timing information propagated to the Timing Pattern Receiver (TPR). Both are implemented with an FPGA solution and configured by EPICS. The poster shows an overall design of the high-level software solutions that meet the physics requirements for LCLS-II timing.

THPHA189	LCLS Machine Protection System High Level Interface Improvements	1885
	C. Bianchini, S. L. Hoobler SLAC, Menlo Park, California, USA
	The Linac Coherent Light Source (LCLS) is a free electron laser (FEL) facility operating at the SLAC National Accelerator Laboratory (SLAC). The LCLS Machine Protection System (MPS) contains thousands of inputs and hundreds of protection interlocks. The inputs and logic configuration are defined in SQLite database files. Real-time state information is hosted by EPICS signals. Control room operators use a Graphical User Interface (MPSGUI) to view and manage faults. The MPSGUI provides a wealth of useful information, from hardware input details to high-level logic flow, but it was difficult for operators to take advantage of this. The workflow required cross-referencing between several screens. This poster presents the greatly improved workflow and usability of the MPSGUI. The requested improvements were defined in meetings between the MPS controls team and the control room operators. The improved GUI allow operators to more quickly respond to MPS faults and diagnose problems reducing troubleshooting time by 20 percent.

The Linac Coherent Light Source (LCLS) is a free electron laser (FEL) facility operating at the SLAC National Accelerator Laboratory (SLAC). The LCLS Machine Protection System (MPS) contains thousands of inputs and hundreds of protection interlocks. The inputs and logic configuration are defined in SQLite database files.

The workflow required cross-referencing between several screens. This poster presents the greatly improved workflow and usability of the MPSGUI. The requested improvements were defined in meetings between the MPS controls team and the control room operators.
