LBL 184-Inch Synchrocyclotron Operational Improvements

Neutron flux-density and secondary-particle energy spectra at the 184-inch synchrocyclotron medical facility.

We have identified the sources of neutron production in the beam transport system of the 720-MeV helium beam used for radiation therapy at the 184-in synchrocyclotron of the Lawrence Berkeley Laboratory, and determined their magnitude. Measurements with activation detectors of differing energy response were used to unfold secondary particle spectra at various locations on the patient table. The...

Operational Performance of the Lbl 88-inch Cyclotron

The 88-Inch Cyclotron began regular operation with the ECR (Electron Cyclotron Resonance) source in January 1985. Since then about 80% of the cyclotron operating schedule has been with the ECR source. The light-ion filament source is used only for runs two or more shifts in length using proton, deuteron, 3He, or alpha beams. Occasionally the polarized ion source is used. The heavy-ion PIG sourc...

Providers now face the prospect of decreased reimbursements and financial penalties associated with quality of care metrics while suppliers must cope with product commoditization and increased scruti...

05 Original 184-189

Objective: To examine smoking habits before and during pregnancy, as well as factors associated with smoking cessation, in three European settings. Methods: Women seeking antenatal care in Ashford (UK), Minorca and Barcelona (Spain) were recruited to the Asthma Multicenter Infant Cohort Study (AMICS). Questionnaires inquiring into the smoking habits of each woman and her partner, demographic da...
