background: oxytocin (ot) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. in this study the development of a receptor imaging tracer for possible tumor imaging has been described. materials and methods: ot was successively labeled with [67ga]-gallium chloride after conjugation with fre...

A single electron in a quantum cyclotron yields new measurements of the electron magnetic moment, given by g/2 = 1.001 159 652 180 73 (28) [0.28 ppt], and the fine structure constant, α−1 = 137.035 999 084 (51) [0.37 ppb], both significantly improved from prior results. The static magnetic and electric fields of a Penning trap confine the electron, and a 100 mK dilution refrigerator cools its c...

Here we present results of the computer design of the structural elements of a compact cyclotron by the example of HITFiL cyclotron selected as the driving accelerator that is under construction at the Institute of Modern Physics (Lanzhou, China). In the article a complex approach to modeling of the compact cyclotron, including calculation of electromagnetic ˇelds of the structural elements and...

The Research Center for Nuclear Physics (RCNP) cyclotron cascade system has been operated to provide high quality beams for various experiments. In order to increase the physics research opportunities, the Azimuthally Varying Field (AVF) cyclotron facility was upgraded recently. A flat-topping system and an 18-GHz superconducting Electron Cyclotron Resonance (ECR) ion source were introduced to ...

This paper reviews a study of a compact superconducting cyclotron to accelerate 200 microamps of protons to 250 MeV. The basic cyclotron structure is the same as that developed in a previous study of a 250 MeV cancer therapy cyclotron, the chief difference in the study reported here being much higher beam current (x10,000) than in the therapy cyclotron to meet desired specifications for the ‘Dr...
