The Los Alamos Neutron Science Center (LANSCE) linear accelerator drives five user facilities: Isotope Production, Proton Radiography, Ultra-Cold Neutrons, Weapons Neutron Research, and Neutron Scattering. In 2011, we started an ambitious project to refurbish key elements of the LANSCE accelerator that have become obsolete or were near end-of-life. The control system went through an upgrade process that affected different areas of LANSCE. Many improvements have been made but funding challenges and LANSCE operational commitments have delayed project deliverables. In this paper, we will discuss our upgrade choices, what we have accomplished so far, what we have learned about upgrading the existing control system and what challenges we still face.

Replacing your accelerator's timing system with a completely different architecture is not something that happens very often. Perhaps even rarer is the requirement that the replacement not interfere with the accelerator's normal operational cycle. In 2014, The Los Alamos Neutron Science Center (LANSCE) began the first phase of a multi-year rolling upgrade project which will eventually result in the complete replacement of the low-level RF system, the timing system, the industrial I/O system, the beam-synchronized data acquisition system, the fast-protect reporting system, and much of the diagnostic equipment. These projects are mostly independent of each other, with their own installation schedules, priorities, and time-lines. All of them, however, must interface with the timing system. This paper will focus on the timing system replacement project, its conversion from a centralized discrete signal distribution system to a more distributed event-driven system, and the challenges faced by having to interface with both the old and new equipment until the upgrade is completed.

  Meeting for users of the Micro Research Finland timing system to share experiences and future needs. We will be having a presentation on the latest products from MRF ' including new VME hardware and active delay drift compensation. We also are soliciting your contributions on interesting things you are doing with your timing system. If you have a paper in the Timing and Synchronization track, this would be an excellent opportunity to give a more technical presentation about your poster or your talk. Additional tutorial: This year we are also considering a 'beginners tutorial' session which will probably be held Tuesday morning after the keynote talk. The idea would be to cover the basic steps for getting started such as: - Initializing the event generator - Setting up a simple sequence - Initializing the event receiver - Setting up a pulser
