	Particle accelerators are complex machines with fast and high power absorption peaks. Power quality is a critical aspect for correct operation. External and internal disturbances can have significant repercussions causing beam losses or severe perturbations. Mastering the load and understanding how network disturbances propagate across the network is a crucial step for developing the grid model and realizing the limits of the existing installations. Despite the fact that several off-the-shelf solutions for real time data acquisition are available, an in-house FPGA based solution was developed to create a distributed measurement system. The system can measure power and power quality on demand as well as acquire raw current and voltage data on a defined trigger, similar to a distributed oscilloscope. In addition, the system allows recording many digital signals from the high voltage switchgear enabling electrical perturbations to be easily correlated with the state of the network. The result is a scalable system with fully customizable software, written specifically for this purpose. The system prototype has been in service for two years and full-scale deployment is currently ongoing.

TUPHA209	MEDICIS High Level Control Application	953
	C. Charrondière, K. Develle, T. Stora CERN, Geneva, Switzerland
	CERN MEDICIS is a research facility that will make radioisotopes for medical applications using the primary proton beam at ISOLDE. It will start operating later in 2017. The high level application for the new beam line is responsible for the control of various equipment, such as power supplies, Faraday cups and scanners, as well as the monitoring of environmental parameters such as the vacuum level. It is characterized by a single user friendly interface to facilitate the operators tasks. In this paper we provide arguments for the chosen solution and give the latest update on the status of the project.

THPHA134	Ground Vibration Monitoring at CERN as Part of the International Seismic Network	1695
	C. Charrondière, M. Cabon, K. Develle, M. Guinchard CERN, Geneva, Switzerland
	The civil engineering activities in the framework of the High Luminosity LHC project, the Geneva GEothermie 2020 and the continuous monitoring of the LHC civil infrastructures triggered the need for the installation of a seismic network at CERN. A 24 bits data acquisition system has been deployed in 3 places at CERN: ATLAS, CMS and the Prévessin site. The system is sending all the raw data to the Swiss Seismological Service and performs FFT on the fly to be stored in the LHC database. The system has shown a good sensitivity of 10^-16 (m/s)2/Hz at 1 Hz.
