The phases of the RF throughout the SLC accelerator complex play an important part not only in the energy and energy spread of the beams at the end of the liiac, but also in the production process of both electrons and positrons. Proper machine operation requires that certain phase relationships be maintained between the RF systems of the electron source, the electron and positron damping rings...
The Iranian Light Source Facility (ILSF) project is the first large scale accelerator facility which is currently under planning in Iran. On the basis of the present design, circumference of the 3 GeV storage ring is 528 m. Beam current and natural beam emittance are 400 mA and 0.477 nm.rad, respectively. Some prototype accelerator components such as high power solid state radio frequency ampli...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
Application of Local Area Networks to Accelerator Control Systems at the Stanford Linear Accelerator
Criticality concerns, decay heat management and radioactive waste handling are perceived as the primary, unsatisfactorily resolved technological problems of nuclear reactors. They all originate from very specific features of a fission phenomenon: self-sustained chain reaction in fissile materials, very strong radioactivity of fission products and very long half-life of some of the radioactive f...
A control system applying reconfigurable computers has been designed and built for the active alignment system of ATF at KEK. The system measures the relative position of accelerator components with a high precision allowing remote correction of the misalignments. A control system that acquires the data and permits the position control was developed. The system was built using reconfigurable lo...
Several years ago, the AGS controls group was given the task of developing software for the RHIC accelerator. Like the AGS, the RHIC control system needs to control and monitor equipment distributed around a relatively large geographic area. A local area network connects this equipment to a collection of UNIX workstations in a central control room. Similar software had been developed for the AG...
The latest addltion to our distributed accelerator control and monitoring system is described which achieves parallel contrcl of multilevel fbncti.ons, multisector access as well as continuous updating of over a00 analog signals. The limitations of the preceding system are compared with the advantages of this larger network. Interface hardware and diagnostic software for the computers is also d...
The Canadian Light Source (CLS) is a 2.9 GeV synchrotron that recently went into service. This paper presents some of the choices made in the design of this facility control system, and lessons learned from the CLS project. Some of the more novel technology choices in the design of the CLS include: (1) fully open source based operating system (RTEMS and Linux); (2) extensive use of fibreoptics ...
