Abstract
A novel muon detector concept for LHC was studied in a test beam. The application
of mean-timer technique to arrays of drift tubes provides the space and
time resolution needed for first level trigger and track reconstructionusing
only the drift time information. A complete study of the performance of
this new concept was done.

The performance of a small prototype chamber of the baseline project for
the muon barrel detector for CMS has been studied in a muon beam. Its efficiency
with different gases and wire diameters, the trigger possibilities and the
response in presence of a large number of electromagnetic secondaries associated

Abstract
The triggering front-end device foreseen in the CMS muon barrel chambers
is the Bunch and Track Identifier (BTI). Although the device can reasonably
be realized only with an ASIC, it can be partially implemented using FPGA
technology. Three FPGA prototypes of BTI were produced in 1995 and tested
on a muon beam during summer 1995 and spring 1996. The results of the test
are summarized in this paper.

Abstract
Three simplified prototypes of the first level trigger front-end device
for the muon barrel drift chambers of CMS were tested on a chamber prototype.
Tests were performed at several incidence angles of a muon beam and with
different magnetic field configurations.
The recorded drift-times were also used to test a full software model reproducing
the actual algorithm applied in the final ASIC being produced.
The efficiency performance of this software model and of the tested prototype
are presented in this paper.

Abstract
The development of the barrel drift chambers for the CMsS muon detector
ot the CERN Large Hadron Collider is supported by a variety of simulation
calculations, based on the GARFIELD drift chamber simulation program and
the GEANT detector simulation package. This study surveys the results influencing
the actual chamber design. The dependence of the drift cell performance
on shape and position of the cell electrodes as well as on the mechanical
tolerances is shown. The results obtained for space-time relation and spatial
resolution are in good agreement to test beam measurements on prototypes.

Abstract
The drift chambers in the barrel region of the CMS detector are exposed
to magnetic stray fields. To study the performance of the muon reconstruction
and the drift times based muon trigger, prototypes were tested under the
expected magnetic field coonditions at the H2 beam facility at CERN. The
results indicate that the overall chamber performance will not be affected.
Only the bunch crossing identification capability in the small region near
pseudorapidity 1.1, corresponding to the border of the solid angle region
covered by the barrel, will be weakened.

Abstract
The 40 MHz bunched beam set up at CERN was used in May 2003 to make a full test of the drift tubes local trigger. The test main goal was to prove that the integration of the various devices located on the chamber was adequately done both on the hardware and software side of the system. Furthermore the test provided complete information about the general performance of the trigger algorithms in terms of efficiency and noise. Data were collected with the default configuration of the trigger devices and with several alternative configurations at various incident angles. Tests on noise suppression and di-muon trigger capability were performed..

Abstract
The drift tubes based CMS barrel muon trigger, which uses self-triggering arrays of drift tubes, is able to perform the identification of the muon parent bunch crossing using a rather sophisticated algorithm. The identification is unique only if the trigger chain is correctly synchronized. Some beam test time was devoted to take data useful to investigate the synchronization of the trigger electronics with the machine clock. Possible alternatives were verified and the dependence on muon track properties was studied.
