Artigo IPEN-doc 24129 A new 124Xe irradiation system for 123I routine production at the 30 MeV IPEN-CNEN/SP cyclotron2017 - LAPOLLI, ANDRE L.; BARCELLOS, HENRIQUE; MATSUDA, HYLTON; SUMIYA, LUIZ C. do A.; JUNQUEIRA, FERNANDO de C.Since 2001 the Nuclear and Energy Research Institute (IPEN/CNEN-SP, Brazil) has produced about 2.5 mCi/mAh of 123I weekly using a manual irradiation system fully developed by its researchers. Ultrapure 123I has been produced and distributed to hospitals and clinics where several diagnostic imaging procedures are done for thyroid, brain and cardiovascular functions. Due to the short half-life and emission of low-energy photons, this radioisotope becomes suitable for diagnosis in children. Currently IPEN researchers are involved in the development of a new fully automated irradiation system dedicated to 123I routine production employing enriched xenon gas (124Xe) as the target material. This new system consists of a target port, a water and a helium cooling system, a cryogenic system, an electric power system, a control and process monitoring unit composed of a supervisory software connected to a Programmable Logic Controller (PLC) via personal computer. In this new concept, there is no need for human interference during radioisotope production, reducing the possibility of eventual failures or incidents involving radioactive material. In this way, with this new system, a specific yield of approximately 3.5 mCi/mAh per irradiation is expected and this will meet a large part of the national demand for this important radioisotope. In the present work will be presented all the technical and constructive aspects of this new system as well as the results obtained in the irradiation of tests.Artigo IPEN-doc 24094 A simple and powerful XY-type current monitor for 30 MeV IPEN/CNEN-SP cyclotron2017 - BARCELLOS, HENRIQUE; MATSUDA, HYLTON; SUMIYA, LUIZ C. do A.; JUNQUEIRA, FERNANDO de C.; COSTA, OSVALDO L. daA water-cooled XY-type current monitor was designed and built in the Cyclotrons Laboratory of the Nuclear and Energy Research Institute (IPEN). It is a very simple design and easily adaptable to the cyclotron beam lines. Tests were done demonstrating to be an instrument of great assistance in proton beam position along beam transport line and target port. Nowadays the XY-type current monitor has been widely used in 18F-FDG routine productions, employing irradiation system which were originally designed for productions on 18 MeV cyclotron accelerator only, however, applying the XY-type current monitor the target port may be exchanged between the 30 MeV and 18 MeV cyclotrons and the observed results are in perfect agreement with expected.Artigo IPEN-doc 21021 Otimização das condições de análise CIDG e, FDG por cromatografia liquida de alta eficiência (CLAE) acoplado a detector amperométrico pulsado (DAP)2015 - CASTRO, THAIS O.M. de; MENGATTI, JAIR; MATSUDA, HYLTON; ARAUJO, ELAINE B. de; FUKUMORI, NEUZA T.O.; MATSUDA, MARGARETH M.N.Artigo IPEN-doc 08823 Sistema para avaliacao, em tempo real, da homogeneidade do feixe externo do Ciclotron Cyclone 30 do IPEN-CNEN/SP2002 - MATSUDA, H.; SCIANI, V.Artigo IPEN-doc 13235 Production of sup(123)I-MIBG at IPEN-CNEN/SP2005 - BARBOZA, M.F. de; SCIANI, V.; HERRERIAS, R.; MATSUDA, M.M.N.; FUKUMORI, N.T.O.; SUMIYA, L.C.A.; MATSUDA, H.; SOUZA, A.A.; GOES, M.M.; PIRES, J.T.; MENGATTI, J.; SILVA, C.P.G.Artigo IPEN-doc 11185 Synthesis and quality control of sup(18)F-FDG at IPEN-CNEN/SP2005 - BARBOZA, M.F.; SCIANI, V.; HERRERIAS, R.; SUMIYA, L.C.; BRUZINGA, W.; GOES, M.M.; BAMBALAS, E.; MARIALVA NETO, A.A.; SOUZA, A.A.; PIRES, J.A.; MATSUDA, H.; MENGATTI, J.; SILVA, C.P.G.Artigo IPEN-doc 07222 Parametros relevantes na irradiacao de agua enriquecida em ciclotron, visando a otimizacao e a seguranca operacional na obtencao do ion sup(18)Fsup(-)2000 - SCIANI, V.; MATSUDA, H.; LAPOLLI, A.L.; SUMIYA, L.C.A.; COSTA, O.L.; LIMA, W.
