A New RF System for the ORIC

IEEE Transactions on Nuclear Science, 1973
The Oak Ridge Isochronous Cyclotron RF system has been converted from an RCA 6949 power amplifier to an RCA 4648 power amplifier. The primary incentive was to reduce tube replacement cost; however, improved system performance and reliability were also realized.

Achievement and measurement of the ORIC magnetic field

Nuclear Instruments and Methods, 1962
The magnetic field for ORIC is achieved by means of conventional main coils requiring 1 MW at maximum energy and internal coils with a power capability of another megawatt. The internal coils include ten pairs of circular trimming coils for shaping the radial gradient, a pair of valley coils in each of three sectors for changing the flutter, and three ...

ORIC RF System - Preparation for HHIRF

IEEE Transactions on Nuclear Science, 1977
The integration of the Oak Ridge Isochronous Cyclotron (ORIC) into the Holifield Heavy Ion Research Facility (HHIRF) requires several RF system modifications to permit injection of ion beams from the 25 MV tandem electrostatic accelerator into ORIC. A new dee eliminates structural interference with the injected beam path and provides an opportunity to ...

The Oric High-Resolution Spectrograph Facility

IEEE Transactions on Nuclear Science, 1966
The installation of a broad-range spectrograph system at ORIC has now been completed. The system consists of a beam analyzing magnet, two triplet quadrupole magnets, and the spectrograph magnet. These magnets are operated as a compound system to obtain optimum energy resolution.

Detection of oriC-Independent Replication in Escherichia coli Cells

2017
In bacteria, replication of the chromosome is normally initiated following the binding of DnaA proteins to the oriC region. However, under certain circumstances, replication can also be initiated independent of the oriC/DnaA system. This is the case, for example, in Escherichia coli cells lacking RNase HI (rnha mutants) or type 1A topoisomerase ...
