The Fermilab Advance Superconducting Test Accelerator (ASTA) under development will be capable of delivering an electron beam with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 1.5 GeV beam energy in the final phase. The completed machine will be capable of sustaining an average beam power of 72 KW at the bunch charge of 3.2 nC. A robust Machine Protection System (MPS) capable of interrupting the beam within a macro-pulse and that interfaces well with new and existing controls system infrastructure is being developed to mitigate and analyze faults related to this relatively high damage potential. This paper will describe the component layers of the MPS system, including a FPGA-based Laser Pulse Controller, the Beam Loss Monitoring system design and the controls and related work done to date.

In recent years, we have packaged the Fermilab accelerator control system, Acnet, so that other instances of it can be deployed independent of the Fermilab infrastructure. This encapsulated "Acnet-in-a-Box" is installed as the detector control system at the NOvA Far Detector. NOvA is a neutrino experiment using a beam of particles produced by the Fermilab accelerators. There are two NOvA detectors: a 330 ton ‘‘Near Detector'' on the Fermilab campus and a 14000 ton ‘‘Far Detector'' 735 km away. All key tiers and aspects of Acnet are available in the NOvA instantiation, including the central device database, java Open Access Clients, erlang front-ends, application consoles, synoptic displays, data logging, and state notifications. Acnet at NOvA is used for power-supply control, monitoring position and strain gauges, environmental control, PLC supervision, relay rack monitoring, and interacting with Epics PVs instrumenting the detector's avalanche photo-diodes. We discuss the challenges of maintaining a control system in a remote location, synchronizing updates between the instances, and improvements made to Acnet as a result of our NOvA experience.
