	In J-PARC MR (Main Ring), we are interested in a commercial product, XPort, a low-cost serial-LAN converter [1]. We have introduced it in two different cases. (1) Two RF-amplifiers with GPIB were introduced. We asked a company to add a XPort for remote control rather than GPIB. Serial messages of GPIB are transported to an EPICS IOC (I/O controller) over our control network. (2) We developed an electric circuit board with manual switches. An on-board FPGA chip has connections both to switches and to XPort pins. Status of switches can be read remotely as UDP messages through XPort. In both cases, messages are converted into EPICS-style records using AsyncDriver of EPICS. Implementation details and operational reports are given.

THPD10	Modular Beam Diagnostics Instrument Design for Cyclotrons	diagnostics, controls, cyclotron, EPICS	154
	N. Chaddha, R.B. Bhole, P.P. Nandy, S. Pal, S. Sahoo VECC, Kolkata, India
	The Cyclotrons at VECC, Kolkata i.e. Room Temperature Cyclotron (RTC) and Superconducting Cyclotron (SCC) comprise of internal and external beam diagnostic systems. These systems provide the beam developer with position, intensity, beam profile, a visual impression of the size & shape of ion beam, and operational control over diagnostic components like 3-finger probe, Beam Viewer probe, Deflector probe, Faraday cup, X-Y slit, Beam viewer etc. Automation of these components was initially done using customized modules for individual sub-system. An expansion of this facility and various levels of complexity demand modular design to cater easy modification and upgradation. The overall requirements are analysed and modular cards are developed based on basic functionalities like valve operation, probe/ slit/ viewer control, position read-out, interlock, aperture control of beam line and communication. A 32-bit Advanced RISC Machine (ARM) based card with embedded EPICS is chosen as the master controller and FPGA/ microcontroller is used for functional modules. The paper gives a comprehensive description of all modules and their integration with the control system.

THPD19	Drive System Control for Kolkata Superconducting Cyclotron Extraction System	controls, cyclotron, feedback, high-voltage	181
	T. Bhattacharyya, S. Bhattacharya, T. Das, C. Nandi, G.P. Pal VECC, Kolkata, India
	The K500 Superconducting Cyclotron at VECC, Kolkata uses two electrostatic deflectors, eight passive magnetic channels, one active magnetic channel and two compensating bars as its extraction elements. Except the active magnetic channel, all the other elements can be moved radially, typically by ±6 mm around a centre position. This maneuverability is due to the fact that not all the ions, spanning the operating region of the cyclotron, will have the same optimum beam extraction radius. At the end of the beam extraction channel, the beam is shaped and aligned by a pair of water cooled slit. The slit movement is pneumatically controlled as it has to be operated in high magnetic field. The computer controlled drive system can move the elements precisely. The paper will describe the drive system and its control mechanism.

THPD36	An Embedded System Based Computer Controlled Process Automation for Recovery and Purification of ^99mTc from (n, γ)⁹⁹Mo	GUI, status, cyclotron, solenoid	211

	⁹⁹Mo produced ^99mTc (t1/2=6hr, 140keV γ-ray) is the most useful radioisotope for nuclear diagnostics. High specific activity ⁹⁹Mo is supplied globally mainly by five old reactors whose routine or unscheduled maintenance shutdown causes supply irregularities that adversely affects patient management in nuclear medicine centres. ^99mTc may also be produced via ⁹⁸Mo(n,γ) in a natural MoO₃ target in reactor or by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ¹⁰⁰Mo(p,2n)^99mTc reaction in cyclotron. To meet the crisis proposals are there to produce ⁹⁹Mo by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ^99mTc directly by ¹⁰⁰Mo(p,2n)^99mTc in a cyclotron. Of the several separation methods of ^99mTc from molybdenum, the most common are adsorption column chromatography, sublimation and liquid-liquid solvent extraction. The conventional methods besides being cumbersome are often hazardous, polluting, require skilled manpower and facilities like fume hood and so are not always practically feasible for hospitals. To address these, VECC and BRIT, Kolkata have collaborated to develop an embedded system based automated ⁹⁹Mo/^99mTc generator from low specific activity ⁹⁹Mo using solvent extraction technique, supervised by a PC based GUI.
