ATLAS Working Group on Front-end Links
Mandate
Aims and objectives
The aim of the working group is to coordinate the development and
testing of optical link components within the ATLAS experiment with
the objectives of minimizing the number of technologies adopted for
the final link solutions and the associated R&D. Emphasis will be placed
on promoting :
- commonality between the SCT and Pixels
for radiation hard 40-80 Mbit/s links
- commonality between LAr, tiles and muon
trigger for radiation tolerant Gbit/s links
The use of commercially available products will be sought wherever
feasible in order to be cost effective.
Fully off-detector links (ROD to ROB) will not be explicitly included
in the activities of the working group as the technical requirements
and timescales are less demanding. However, as there are many common
issues, those working on ROD-ROB links will participate in the working
group to promote the exchange of information and experience.
The primary responsibility for the work will remain with the
sub-detector systems, but the group will help to coordinate :
- specification of requirements
- information on the availability of suitable components
- radiation tests
- evaluation of commercial products
- provision and sharing of test equipment
- a common laboratory for infrastructure
- installation of fibres and connectors at ATLAS
- contacts with industry
- contacts with other experiments
- estimations of costs
- general dissemination of information (via WWW).
Membership
Participation in the group is open to all those working on ATLAS optical
links; the working group will include at a minimum :
- The working group coordinators
- One representative for each of the interested systems [1]
- The CERN 'link' person
- The electronics coordinators.
Reporting
Formally, the group will report to the electronics coordinators but will
also report to other bodies as appropriate (subdetector systems, EB etc.)
