	Baby Cyclotrons that made in Self-shield type have been employed for use in Medical center for the diagnosis of cancer diseases by positron emission tomography (PET) system. Here in we have done a discussion on gamma and neutron dose rates at a distance of one meter outside of the cyclotron shielding. This shield consist of Lead, polyethylene borated (10% Boron) layers from inside to outside respectively. With increasing the thickness of lead and polyethylene we will see a decrease in the gamma and neutron dose which received by the water phantom at a distance of one meter outside from the surface of the shield of the cyclotron. Note that the gamma and neutron dose at the beginning (without any shielding) was on the order of several thousand μSv per hour that by achieve to a certain amount of thickness of the shield, the dose was reduced to below of the limited level. In this study, the MCNPX Code has been used. In MCNPX Code that used the variance reduction techniques for decreasing relative errors of calculation which was a good method for this case study.

TUP09	Diagnostic Tool and Instrumentation for Handling 50 kW Beam Power	cyclotron, diagnostics, instrumentation, proton	184
	P. Antonini, E. Boratto, A. Calore, D. Campo, J. Esposito, A. Lombardi, M. Maggiore, M. Poggi, L. Pranovi INFN/LNL, Legnaro (PD), Italy
	The SPES facility is entered the commissioning phase and the 70 MeV cyclotron is delivering the proton beams at the maximum power permitted. The INFN team has developed additional beam instrumentation in order to stop the particles at different power allowing the tuning of the beamline and to check the particles losses during the transport. In particular, a beam dumper able to stop up to 55kW beam power has been constructed and tested as well as the beam loss monitor system by INFN team. Here we present the status of the beam instrumentations supplied by INFN and the results achieved during the test with the beam.

	B. Nactergal, M. Abs, S. De Neuter, W.J.G.M. Kleeven, E.K. Kral, V. Nuttens, S. Zaremba, J. van de Walle IBA, Louvain-la-Neuve, Belgium
	About 15 months ago, at IBA, we have launched the design, construction, tests and industrialization of an innovative isochronous cyclotron for PET isotope production (patent applications pending). The design has been optimized for cost effectiveness, compactness, ease of maintenance, activation reduction and high performances, with a particular emphasis on its application on market. Multiple target stations can be placed around the vacuum chamber. An innovative extraction method (patent applications pending) has been designed which allows to obtain the same extracted beam sizes and properties on the target window independent of the target position.

THP02	Planning Considerations for Radioisotope Production Cyclotron Projects - Regulatory Feedback	cyclotron, operation, controls, target	303
	A.N. Alwani CNSC, Ottawa, Canada
	Over the last ten years, there has been a significant increase in projects to build, operate or upgrade cyclotrons in Canada. This is largely driven by their increased use for the production of radioisotopes. The Canadian Nuclear Safety Commission regulates the use of nuclear energy and materials to protect health, safety, security and the environment in Canada. Its mandate includes the oversight of particle accelerators. The CNSC regulates the full life cycle of such facilities, with regulatory oversight though construction, commissioning, operation, and decommissioning activities. This paper outlines common practices for such projects, highlighting the particular aspects that should be considered in the early stages of project planning and providing examples of best practices and challenges that, if properly addressed, help ensure continued safe operation of the facility through its entire life cycle. The paper discusses the necessary elements of effective planning for such projects, touching on layout and space considerations; workload projection and maximum research capacity; shielding penetrations; cooling water circuit activity; storage of active components; management of radioactive waste from cyclotron and processing labs; construction and commissioning project management; integration of equipment safety systems and building safety systems; nuclear ventilation and filtration options; and strategies for staffing and training.
