Thoughts about an R&D collaboration on Detector Mechanics and Cooling

Forum on Tracking Detector Mechanics 2019, Cornell University Burkhard Schmidt, Experimental Physics Department, CERNJune 20, 2019

2 About R&D collaborations

Most R&D collaborations have been a great success and have been well received Some Feedback from the ESPPU meeting in Granada, May 13-16, 2019:

CERN

RD Projects

Good examples of coordination towards common goals

RD42 – Diamond detectors

RD50 – Silicon radiation hard devices

RD51 – Micropattern gas detectorsRD53 – Pixel readout chip for ATLAS and CMS...and several others in the pastIn general, large collaborations of interacting institutes.Good model, butFocus can be lost and people just “keep going” regular reassessment important.Resources always a problem – especially people.CERN is central, but support needed from other labs and agencies

International R&D program offer

Gather worldwide expertise in all aspects and provide visible framework for institutions

HEP involved in innovation and various experimental programs, but also

material science and device producers

Develop/provide access to common tools (sharing cost and work)

Modelling, ex. TCAD (RD50)

Characterization,

ex. TCT technique (RD50), source (laser/particles), test benches, readout systemsPossibility of common order of samplesCommon test protocols, documentation, data bases of results and beam test infrastructuresWork structure and coordinationTo limit duplication (dead-ends) and share work per areasCan include non HEP developmentsex. medical imaging in RD18 (Crystal Clear)Collaboration Boards can streamline activities and make recommendations while preserving diversity approachWide dissemination of knowledge and approved resultsPublications, conferences, dedicated workshops, schools

Large network for exchange of information

Active environment for training and to create new expertise

RD51: 400 members, 90 institutes in 29 countries institutes

Typical HEP program timeline (R&D in blue)

R&D timescale is ≃ 10 years, approved experimental programs are natural drivers for techniques and resources, technology innovation can suffer cycle/migration effects

Given the encouraging feedback in general, we should think how to organize ourselves best to carry out R&D on Detector Mechanics.Positive Aspects of an R&D collaboration:

It will act as facilitator to carry out common research plans and activities. It simplifies in the exchange of students between participating institutes.It will help to get prepared and organized for ‘what comes next’The regular reviewing process is generally appreciated by the Funding Agencies and might

help the participating institutes to get resources. B

etter dissemination of knowledge and results

Still, we should not overlook that an R&D collaboration comes

not for

free:

It

requires work to prepare the proposal for approval by the CERN Research BoardSome colleagues (who must be identified) need to take time to lead the effort It will take resources to coordinate the work of the different research lines We should be sure that at he end the community benefits from it!The organizational model could follow closely the one of RD50 and RD51.We could also benefit from existing MoUs for these collaborations.5 Comments regarding R&D on Detector Mechanics

The execution of the R&D Programme is subject to the General Conditions applicable to Experiments at CERNThe

General Conditions define the representation of the parties involved in the R&D Programme and the basic documents that govern its execution.They set out in general terms the organisation of the Collaboration, CERN’s obligations as Host Laboratory and the obligations of the Collaborating Institutions. They also address the questions of liability and dispute resolution, as well as matters related to intellectual property.

The General Conditions are an integral part of the MoU

of any R&D collaboration.

A

n

R&D Proposal

has to be submitted to the LHCC, followed by a

detailed review of the scientific merits, the technological feasibility and estimates of the resources needed.For approval, the LHCC has to recommended the Proposal to the CERN Research Board.6 General comments regarding R&D collaborations

If we plan to go ahead we should decide soon so that the collaboration could be shaped in autumn.The timing is good: also the preparation of proposals for ‘AIDA next’ has been launched (deadline: March 17, 2020).

The exact relation between the ‘AIDA next’ and an R&D collaboration needs to be well understood; they can complement each other. With an R&D collaboration we are not dependent on the EU decision process and retain more flexibility. The typical duration of an R&D programme is 5 years with the possibility of renewal. Institutes desiring to contribute to such an R&D initiative with an appropriate research plan and some resources and infrastructure would be welcome.

The initiative to form an R&D collaboration is in general well received at CERN.

0. Should we go ahead ? In case we agree to go ahead:What should be the scope of such an R&D collaboration on Detector Mechanics ?

Should other research lines be added ?What should be the granularity of the research lines ?Who would be interested to join such an R&D collaboration, and with which main research interest We should form a small team of people to prepare a proposal

Who would be willing to help and contribute?

Some Questions

BACkup10

R&D has multiple dimensions

Technologies can apply to different detectors with specific engineering developments and with several variants depending on beam conditions, experiment configurations and performance goals*

Trend toward monolithic devices also tend to blur the usual boundaries with ancillary components

R&D programs can be organized with focus on technology innovation, detector application, experiments/beam condition requirements - Ancillary components are good candidates for cross-detector/experiment developments

Planning R&D for future

experiments

Identifying a series of R&D programs with appropriate balance of orientations and defined timelines seems efficient to provide wide variety of required detectors while minimizing duplication of effort

Costs tend to increase with complexity of devices and need for several iterations

Order of few MCHF M&S for new devices to enter a first experiment

ex. 65 nm ASIC development cost is high for large chips, becoming comparable to production cost

ex. LGADs + electronics developments cost also become close to detector cost

Feeling from actors that more funding for innovation could have enabled devices with improved performance and/or lower cost for HL-LHC; plausible ex. more radiation tolerant Crystals, SiPMs, CMOS sensors with fast readout…Resources are in the hand of contributing institutionsEstimating efforts needed/invested is not easy with sometime defections that can impact schedulesMore formal agreements in R&D phases could helpCERN strategic R&D program proposal for future experiments, a “cluster” approach (re-)align detectors and technologies (program and experimental concepts to be selected), identify common ancillary component developments and include magnets and software8 Work Packages https://cds.cern.ch/record/2649646 Presentation of Didier Contardo
