MOPMN028	Automated Voltage Control in LHCb	controls, detector, experiment, status	304
	L.G. Cardoso, C. Gaspar, R. Jacobsson CERN, Geneva, Switzerland
	LHCb is one of the 4 LHC experiments. In order to ensure the safety of the detector and to maximize efficiency, LHCb needs to coordinate its own operations, in particular the voltage configuration of the different sub-detectors, according to the accelerator status. A control software has been developed for this purpose, based on the Finite State Machine toolkit and the SCADA system used for control throughout LHCb (and the other LHC experiments). This software permits to efficiently drive both the Low Voltage (LV) and High Voltage (HV) systems of the 10 different sub-detectors that constitute LHCb, setting each sub-system to the required voltage (easily configurable at run-time) based on the accelerator state. The control software is also responsible for monitoring the state of the Sub-detector voltages and adding it to the event data in the form of status-bits. Safe and yet flexible operation of the LHCb detector has been obtained and automatic actions, triggered by the state changes of the accelerator, have been implemented. This paper will detail the implementation of the voltage control software, its flexible run-time configuration and its usage in the LHCb experiment.

MOPMS036	Upgrade of the Nuclotron Extracted Beam Diagnostic Subsystem.	controls, hardware, operation, software	415
	E.V. Gorbachev, N.I. Lebedev, N.V. Pilyar, S. Romanov, T.V. Rukoyatkina, V. Volkov JINR, Dubna, Moscow Region, Russia
	The subsystem is intended for the Nuclotron extracted beam parameters measurement. Multiwire proportional chambers are used for transversal beam profiles mesurements in four points of the beam transfer line. Gas amplification values are tuned by high voltage power supplies adjustments. The extracted beam intensity is measured by means of ionization chamber, variable gain current amplifier DDPCA-300 and voltage-to-frequency converter. The data is processed by industrial PC with National Instruments DAQ modules. The client-server distributed application written in LabView environment allows operators to control hardware and obtain measurement results over TCP/IP network.

	Power Linear Induction Accelerator (LIA) for flash radiography is commissioned in Budker Institute of Nuclear Physics (BINP) in Novosibirsk. It is a facility producing pulsed electron beam with energy 2 MeV, current 1 kA and spot size less than 2 mm. Beam quality and reliability of facility are required for radiography experiments. Features and structure of distributed control system ensuring these demands are discussed. Control system hardware based on CompactPCI and PMC standards is embedded directly into power pulsed generators. CAN-BUS and Ethernet are used as interconnection protocols. Parameters and essential details for measuring equipment and control electronics produced in BINP and available COTS are presented. The first results of the control system commissioning, reliability and hardware vitality are discussed.

	High Voltage Splitter (HVS) is an equipment designed in Alba that allows a high voltage (HV) distribution (up to +7kV) from one ion pump controller up to eight ion pumps. Using it, the total number of high voltage power supplies needed in Alba's vacuum installation has decreased significantly. The current drawn by each splitter channel is measured independently inside a range from 10nA up to 10mA with 5% accuracy, those measurements are a base for vacuum pressure calculations. A relation, current-pressure depends mostly on the ion pump type, so different tools providing the full calibration flexibility have been implemented. Splitter settings, status and recorded data are accessible over a 10/100 Base-T Ethernet network, none the less a local (manual) control was implemented mostly for service purposes. The device supports also additional functions as a HV cable interlock, pressure interlock output cooperating with the facility's Equipment Protection System (EPS), programmable pressure warnings/alarms and automatic calibration process based on an external current source. This paper describes the project, functionality, implementation, installation and operation as a part of the vacuum system at Alba.
