The ATLAS Pixel Detector is the innermost layer of the ATLAS tracking system and will contribute significantly to the ATLAS track and vertex reconstruction. The detector consists of identical ...sensor-chip-hybrid modules, arranged in three barrels in the centre and three disks on either side for the forward region. The position of the Pixel Detector near the interaction point requires excellent radiation hardness, mechanical and thermal robustness, good long-term stability, all combined with a low material budget. The detector layout, results from final prototyping and the status of production are presented.
The innermost part of the ATLAS (A Toroidal LHC ApparatuS) experiment at the
LHC (Large Hadron Collider) will be a pixel detector, which is presently under
construction. Once installed into the ...experimental area, access will be
extremely limited. To ensure that the integrated detector assembly operates as
expected, a fraction of the detector which includes the power supplies and
monitoring system, the optical readout, and the pixel modules themselves, has
been assembled and operated in a laboratory setting for what we refer to as
system tests. Results from these tests are presented.
Nucl.Instrum.Meth. A565 (2006) 113-118 We prove and demonstrate here for the example of the large scale pixel
detector of ATLAS that Serial Powering of pixel modules is a viable alternative
and that ...has been devised and implemented for ATLAS pixel modules using
dedicated on-chip voltage regulators and modified flex hybrids circuits. The
equivalent of a pixel ladder consisting of six serially powered pixel modules
with about 0.3Mpixels has been built and the performance with respect to noise
and threshold stability and operation failures has been studied. We believe
that Serial Powering in general will be necessary for future large scale
tracking detectors.

J.Phys. G26 (2000) 551-592 The Beyond the Standard Model Working Group discussed a variety of topics
relating to exotic searches at current and future colliders, and the
phenomenology of current ...models beyond the Standard Model. For example, various
supersymmetric (SUSY) and extra dimensions search possibilities and constraints
are presented. Fine-tuning implications of SUSY searches are derived. The
implications of Higgs (non)-discovery are discussed, as well as the program
HDECAY. The individual contributions are included seperately. Much of the
enclosed work is original, although some is reviewed.
