Unfolding algorithms and tests using RooUnfold

Tim Adye
The RooUnfold package provides a common framework to evaluate and use different unfolding algorithms, side-by-side. It currently provides implementations or interfaces for the Iterative Bayes, Singular Value Decomposition, and TUnfold methods, as well as bin-by-bin and matrix inversion reference methods. Common tools provide covariance matrix evaluation and multi-dimensional unfolding. A test suite allows comparisons of the performance of the algorithms under different truth and measurement models. Here I outline the package, the unfolding methods, and...

High Brightness Proton Beams for LHC: Needs and Means

Michael Benedikt & R Garoby
Experiments [1, 2] have proven that the LHC injector chain can deliver a proton beam with the nominal characteristics (bunch intensity Nb=1.15E11 protons per bunch (ppb) in normalised rms transverse emittances of 3.5 mm.mrad), but cannot reach the ultimate performance (1.7E11 ppb in the same emittances). Moreover, in the longer term, an even higher beam brightness is required by all methods considered for increasing the LHC luminosity beyond the present ultimate level. Improvements and/or new...

The decay of neutron deficient /sup 117,119m+g/, /sup 121m+g/Cs Low lying level structure in /sup 117,119,121/Xe nuclei

A Knipper, Claude Serre, J Genevey, A Charvet, J Crawford & G Marguier
The decays of neutron-deficient /sup 117/Cs, /sup 119m+g/Cs, /sup 121m +g/Cs have been investigated. Systematics of low-lying energy levels, both in cesium and xenon nuclei are presented. (13 refs).

Dealing with distributed intelligence in monitoring and control systems

R A McLaren
The European Hybrid Spectrometer is built up of many individual detectors, each having widely varying monitoring and control requirements. With the advent of cheap microprocessor systems a shift from the concept of a single monitoring and control computer to that of distributed intelligent controllers has been economically feasible. A detector designer can now thoroughly test and debug a complete monitoring and control system on a local, dedicated micro-computer, while during operation, the central computer can...

Beam-beam interactions

Werner Herr
One of the most severe limitations in high intensity particle colliders is the beam-beam interaction, i.e. the perturbation of the beams as they cross the opposing beam. This introduction to beam-beam effects concentrates on a description of the phenomena that are present in modern colliding beams facilities.

High-Resolution Time-to-Digital Converter in Field Programmable Gate Array

V Izzo, R Lomoro, A Aloisio, S Loffredo, P Branchini, R Giordano & R Cicalese
Two high-resolution time-interval measuring systems implemented in a SRAM-based FPGA device are presented. The two methods ought to be used for time interpolation within the system clock cycle. We designed and built a PCB hosting a Virtex-5 Xilinx FPGA. We exploited high stability oscillators to test the two different architectures. In the first method, dedicated carry lines are used to perform fine time measurement, while in the second one a differential tapped delay line is...
