Introduction The vertical misalignment of coil fields with respect to iron fields in cyclotrons can lead to significant beam losses in the course of beam extraction. During commissioning of the Coupled Cyclotron Project at the NSCL unusually high beam losses have been observed on an extraction magnetic element of the K500 cyclotron. The beam loss was first observed on the beam current profiles ...

[18f]kf, considered as a reference standard for positron emission tomography of the skeletal system, was produced by the bombardment of enriched water ([18o]h2o>95%) with high energy protons in nrcam cyclotron. after the extraction of fluoride from enriched water as kf, and passing it through microbial filter and fine adjustment of acidity and osmolality, it was converted into an injectable for...

We report on an observation of the low-mass X–ray binary 4U1626–67 performed during the BeppoSAX Science Verification Phase. An absorption feature at ∼ 37 keV, attributable to electron cyclotron resonance, has been discovered in its pulse averaged spectrum. The inferred neutron star magnetic field strength is 3.2 · (1 + z) × 10 12 G, where z is the gravitational redshift. The feature is deep an...

We have carried out an ultrahigh-field cyclotron resonance (CR) study of p-type In1−xMnxAs films, with Mn composition x ranging from 0 to 2.5%, grown on GaAs by low-temperature molecular-beam epitaxy. Pulsed magnetic fields up to 500 T were used to make cyclotron resonance observable in these low-mobility samples. Clear CR spectra have been observed for all the samples at high fields in the meg...

[1] Titan’s dense atmosphere is thought to be an important source of pickup ions in the Saturnian magnetosphere. Cassini spacecraft measurements of the plasmas near Titan show evidence of pickup ions, yet electromagnetic ion cyclotron waves, which are direct indicators of ion pickup, have not yet been detected. Pickup ions and their associated ion cyclotron waves have been observed at Saturn’s ...

[18F]KF, considered as a reference standard for positron emission tomography of the skeletal system, was produced by the bombardment of enriched water ([18O]H2O>95%) with high energy protons in NRCAM cyclotron.

Until recently PET scanning has been available only at major universities or teaching hospitals possessing the necessary resources and expertise to operate a research PET facility. Most dedicated PET centers cost several millions of dollars, and include a cyclotron, a radiochemistry laboratory to synthesize PET radiopharmaceuticals, a multicrystal dedicated PET camera, advanced computer f...
