	For controlling all the equipment and services required for operating the 10 MeV baby cyclotron and optimizing various parameters, an extensive control system is used. Most of the control systems are located in the control room which is situated outside the biological shield. The control console in the control room has switches for all the power supplies like main magnet, radio frequency system, vacuum system, ion-source, deflector, etc. Several Programmable Logic Controllers (PLC's) which are located near the equipment control the whole system. A technique of Supervisory Control and Data Acquisition (SCADA) is presented to monitor, control, and log actions of the PLC's on a PC through use of I/O communication interface coupled with an Open Process Control/Object Linking and Embedding [OLE] for Process Control (OPC) Server/Client architecture. In order to monitor and control different part of system, OPC data is then linked to a National Instruments (NI) LabVIEW. In this paper, details of the architecture and insight into applicability to other systems are presented.

	N.V. Avreline, W. Gyles, R.L. Watt ACSI, Richmond, B.C., Canada
	A new magnetic field mapper was designed and built to provide increased accuracy of cyclotron magnetic field measurements. This mapper was designed for mapping the magnetic fields of TR-19, TR-24, and TR-30 cyclotron magnets manufactured by Advanced Cyclotron Systems Inc. A Group3 MPT-141 Hall Probe (HP) with measurement range from 2 G to 21 kG was used in the mapper’s design. The analogue monitor output was used to allow fast reading of the Hall voltage. Use of a fast ADC NI9239 module and error reduction algorithms, based on a polynomial regression method, allowed the reduction of noise to 0.2 G. The HP arm was made as a carbon fibre foam sandwich. This rigid structure kept the HP arm in a flat plane within 0.1 mm. In order to measure the high gradient field, the design of this mapper provided high resolution of HP arm angle within 0.0005° and of radial position within 25 μm. A set of National Instrument interfaces connected through a network to a desktop computer were used as a base of control and data acquisition systems. The mapper was successfully used to map TR-19 and TR-24 cyclotron magnets.

	In this work, we present a new combined system which produces FDG and NaF in separate runs. The needed for synthesis this radiopharmaceuticals are obtained by bombardment of highly enriched water with proton. The aim is development of routine systems to use with baby cyclotrons. In this study, the various chemical steps and required reagents as well as different reagent delivery methods has been investigated. This evaluation has been done with purpose of optimizing the performance of a conceptually simple device integrated into a fully automated synthesis procedure for radiosynthesis of FDG and NaF. In this system, we have used AVR microcontroller to control the process and LabVIEW software for monitoring the operation of system. Furthermore, Geiger Muller counters have been used to determine the activity to insure the accuracy of the systems operation.
