Band structure in /sup 148/Ce from the decay of mass separated /sup 148/La

C Chung, H I Liou, D S Brenner, F K Wohn, W B Walters, H Yamamoto, K Sistemich, R L Gill, M Shmid, G M Gowdy & R E Chrien
The $beta$ decay of $^{148}$La to levels in $^{148}$Ce has been studied at the TRISTAN ISOL facility at Brookhaven National Laboratory's High Flux Beam Reactor. A level scheme for $^{148}$Ce is presented which identifies a first excited 0$^{+}$ state at 770.16 KeV. 0$^{+}$, 2$^{+}$ and 4$^{+}$ members of the ground state band, as well as 0$^{+}_{\beta}$, 2$^{+}_{\beta}$, 4$^{+}_{\beta}$, 2$^{+}_{\gamma}$, 3^${+}_{\gamma}$ and the 1$^{-}$ and 3$^{-}$ members of an octupole band are identified.

PYTHON-based Physics Analysis Environment for LHCb

I Belyaev, A Yu Tsaregorodtsev, E De Oliveira, P Mato, G Barrand, M Frank, A Tsaregorodtsev & E De Oliveira
BENDER is the PYTHON based physics analysis application for LHCb. It combines the best features of the underlying GAUDI software architecture with the flexibility of the PYTHON scripting language and provides end-users with a friendly physics analysis oriented environment.

RF transport

Stefan Choroba
This paper deals with the techniques of transport of high-power radiofrequency (RF) power from a RF power source to the cavities of an accelerator. Since the theory of electromagnetic waves in waveguides and of waveguide components is very well explained in a number of excellent text books it will limit itself on special waveguide distributions and on a number of, although not complete list of, special problems which sometimes occur in RF power transportation systems.

An RPC-based Technical Trigger for the CMS Experiment

F Fabozzi, S Natali, C Pucci, A Ranieri, V. Panev, M Iskanius, A Colaleo, F Felli, M Abbrescia, M Bertani, T Tuuva, G Saviano, D Colonna, M Pallotta, Ignacy M Kudla, R Trentadue, A Dimitrov, A Paolozzi, P Petkov, A Grelli, B Pavlov, P Torre, R Liuzzi, B Marangelli, G Wrochna … & G Polese
In the CMS experiment, sub-detectors may send special trigger signals, called "Technical Triggers", for special purposes like test and calibration. The Resistive Plate Chambers are part of the Muon Trigger System of the experiment, but might also produce a cosmic muon trigger as Technical Trigger to be used during the commissioning to the detectors, the CMS magnet Test Cosmic Challenge and the later running of CMS. The proposed implementation is based on the development of...

High Luminosity Muon Collider Design

R B Palmer & J C Gallardo
Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadrons and electron machines. They should be regarded as complementary. Parameters are given of a 4 TeV high luminosity muon-muon collider, and of a 0.5 TeV demonstration machine. We discuss the various systems in such muon collider.

Gauges for fine and high vacuum

K Jousten
Vacuum gauges for use in accelerators have to cover about 17 decades of pressure, from 10–12 Pa to 105 Pa. In this article we describe the history, measurement mode, design, accuracy and calibration of the gauges used down to 10–5 Pa. We focus on commercially available types of gauges, i.e., mechanical gauges, piezoresistive and capacitance diaphragm gauges, thermal conductivity gauges, and spinning rotor gauges.

$\overline{p}$p elastic scattering and two-body annihilations at 6.2 GeV/c

Arne Lundby
Some recent results of a proportional- and spark-chamber experiment made at the CERN Proton Synchrotron are presented. It is shown how pp to pp compares with pp to pp at 5.0 and 6.2 GeV/c. A large difference is observed in the 90 degrees C c.m. region. Results on annihilations into pi /sup +/ pi /sup -/ and K/sup +/K/sup -/ are presented. Comparisons are made with pi p elastic data in the large-angle region. (8...
