This is the first announcement for the "Workshop on Quality Issues in Current and Future Silicon Detectors" held at CERN, 3-4 November 2011. It would be a pleasure for us to welcome you at CERN to this event.
2. Why have a Workshop on Quality Issues in Current and Future Silicon Detectors?
In May 2001 was held the Workshop on QA Issues in Silicon Detectors. That workshop was well attended and focused primarily on the QA planning and implementation for silicon sensors to be used in the LHC experiments. It was always intended to have a “follow-up” workshop to evaluate the results of the LHC experience and look at how this could be used to improve the next generation of silicon detectors.
Although it has been 10 years since that first workshop, we just now have significant running experience with the LHC experiments and therefore the time seems appropriate to have a follow-up workshop.
The workshop will bring together experts from the LHC and other high energy physics (HEP) experiments using large silicon tracking detectors. Those involved in the design, construction, commissioning and operation of the current detectors as well as those involved in the R&D, design or construction of future detectors are invited to attend.
3.Scope of this workshop
The focus of this workshop is somewhat different than that of 10 years ago in that primary subject is not so much silicon sensors but a larger view of silicon tracking detector systems. We would like to review in detail the challenges and unexpected problems encountered in recent large silicon detector construction and operation. In this way we can help communicate the lessons learned so that this can be applied to the next generation of detectors. The main topics concerning silicon detectors we would like to examine are those believed to have had the most QA issues, namely, the sensors, the modules, the integration plus system aspects, and the cooling systems. The focus will always be on the quality issues encountered in the construction, testing, integration, commissioning and operation of the components, modules, on up to the full detector system.
There will be some presentations of a general nature on selected topics by invited speakers. The majority of presentations will concern quality related issues encountered on specific projects (usually sub-systems of an experiment). We envisage dividing the subject into the following sessions (time allocations are preliminary and could change):
Session 1: Overview, general quality issues, and non-HEP QA experience (~90 minutes, session convener: Alan Honma - CERN)
Session 2: Sensors and other critical single components (~90 minutes, session convener TBA)
Session 3: Module interconnects (wire bonding and bump-bonding) (~120 minutes, session convener: Michael Campbell - CERN)
Session 4: Modules (front-end electronics, support structures, assembly, testing) (~180 minutes, session convener: Anthony Affolder – U. Liverpool, to be confirmed)
Session 5: Integration into larger structures (e.g. ATLAS staves, CMS rods) up to the full detector system (~120 minutes, session convener TBA)
Session 6: Cooling systems (~120 minutes, session convener Paolo Petagna, CERN)
Presentations are generally by invitation only. However, contributions may be accepted if considered to be of high interest by the Programme Committee. Participants with a possible contribution should contact the chairman by email Alan Honma before September 29.
We are planning to have special topical talks on quality issues in the following areas:
NASA projects, sensor (Kazuhisa Yamamura - Hamamatsu,), wire bonding (Ian McGill – CERN), bump-bonding (Sami Vähänen – VTT), PCB fabrication (Rui de Oliveira -CERN), PCB assembly (Sylvain Kaufmann - CERN), module assembly (Thomas Fritsch - IZM), and possibly a few other topics.
5. Registration / Deadline / Collection of Presentations ("Proceedings")
We would appreciate if you could use the online registration form on the Workshop home page.
The workshop will be limited to a maximum of 80 participants. (Note: this has been increased to 100 as of Sept. 24)
There are no registration fees for the workshop. Refreshments at coffee breaks will be provided but lunches are not included. There will be a charge of 80 CHF/Person for the (optional) workshop dinner to be held Thursday evening, 3 November, in the CERN Globe. Receipts for the dinner fee will be available.
All presentations should be made available on the web. Written articles are not foreseen.
