A Scintillating-fiber Beam Profile Monitor for the DAFNE BTF
A scintillating-fiber beam profile detector has been designed, built and tested, for the monitoring of the position and size of the electron beam of the DAFNE, the recently commissioned electron beam-test facility at the Frascati LNF. A description of the detector construction and assembly, together with the results achieved during the 2003-2004 run, are here reported.
Commissioning of the DAΦNE beam test facility
Abstract The DAΦNE Beam Test Facility (BTF) is a beam transfer line optimized for the production of electron or positron bunches, in a wide range of multiplicities and down to single-electron mode, in the energy range between 50 and 800 MeV . The typical pulse duration is 10 ns and the maximum repetition rate is 50 Hz . The facility design has been optimized for detector calibration purposes. The BTF has been successfully commissioned in February 2002 and started operation in the same year in November. The schemes of operation, the commissioning results, as well as the first users’ experience are reported here.
The Evolution of the DAPHNE control system: A History of liberation from hardware
During the DAFNE [1] commissioning and run operations the Control System [2] has been continuously evolving in order to fulfill the user requirements and the needs of a complete accelerator management. The original structure of distributed CPUs relaying to a central shared memory proved to be scalable and suitable for adding functionality ’on the fly’. After 5 years of operation, the system had reached some intrinsic limits so that we focused on an upgrade plan mainly regarding the user level and the capability of the system to connect to external resources. The re-engineering was done thinking to the maximum software reuse and the original choice of a commercial software environment for all the control applications demonstrated to be valid allowing to redesign the user level with no worries for the porting.
