THPHA075 | FPGA-based BPM Data Acquisition for LCLS-II | 1560 |
|
||
The LCLS-II facility currently under construction at SLAC will be capable of delivering an electron beam at a rate of up to almost 1MHz. The BPM system (and other diagnostics) are required to acquire time-stamped readings for each individual bunch. The high rate mandates that the processing algorithms as well as data exchange with other high-performance systems such as MPS (machine-protection system) or bunch-length monitors are implemented with FPGA technology. Our BPM-processing firmware builds on top of the SLAC "common-platform" [*] and integrates tightly with core services provided by the platform such as timing, data-buffering and communication channels.

THPHA189 | LCLS Machine Protection System High Level Interface Improvements | 1885 |
|
||
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. | ||
