S11LLC08	Non-Destructive Fast Data Taking System of Beam Profile and Momentum Spread in KEK-PS	synchrotron, acceleration, electron, injection	399
	T. Kawakubo, T. Adachi, Y. Ajima, E. Kadokura KEK, Ibaraki, Japan T. Ishida Mitsubishi Electric Corporation, Tokyo, Japan
	A mountain view of beam profiles in a synchrotron ring can be taken without any beam destruction by collecting charged particles produced by the circulating beam hitting residual gas in the ring to a sensor. When a rectangular Micro Channel Plate with multi-anodes or lined-up electron multipliers is used as the sensor, the profiles can be measured within one acceleration period, even if the beam intensity is very low and the ring is kept in a high vacuum. We describe this non-destructive profile monitor (NDPM) as well as the momentum spread measurement system by a combination of two sets of NDPM.

S13MMI07	X-Window for Process Control in a Mixed Hardware Environment	controls, network, cryogenics, hardware	471
	M.R. Clausen, K. Rehlich DESY, Hamburg, Germany
	X-Window is a common standard for display purposes on the current workstations. The possibility to create more than one window on a single screen enables the operators to gain more information about the process. Multiple windows from different control systems using mixed hardware is one of the problems this paper will describe. The experience shows that X-Window is a standard per definition, but not in any case. But it is an excellent tool to separate data-acquisition and display from each other over long distances using different types of hardware and software for communications and display. Our experience with X-Window displays for the cryogenic control system and the vacuum control system at HERA on DEC and SUN hardware will be described.

When a rectangular Micro Channel Plate with multi-anodes or lined-up electron multipliers is used as the sensor, the profiles can be measured within one acceleration period, even if the beam intensity is very low and the ring is kept in a high vacuum.

Control protocol provides a normalized access procedure for equipment of the same kind from a control system. Modelisation and the subsequent identification of functionalities with their parameters, variables and attributes have now been carried out at CERN for representative families of devices. ISO specifications, such as the ASN.1 metalanguage for data structure representation and MMS definitions and services have, to some extent, been introduced in the design for generality and compatibility with external world. The final product of this design is totally independent of the control systems and permits object oriented implementations in any controls frame. The present paper describes the different phases of the project with a short overview of the various implementations under development at CERN.
