Generic Detector R&D for an Electron Ion Collider Advisory Committee meeting January 13-14, 2014 T. Ludlam NSAC 2013 Subcommittee Report on Scientific Facilities: “The Subcommittee ranks an EIC as Absolutely Central in its ability to contribute to world-leading science in the next decade.” “There are outstanding R&D issues that remain to be addressed in order to achieve performance metrics.... Both laboratories are actively addressing R&D issues and are making good progress.” A Charge to NSAC to initiate a Long Range Plan process later this year seems imminent.

EIC Generic Detector R&D Program Establish a peer reviewed program of R&D to enable EIC experiments Program initiated January 2011 with first call for proposals. This is the fifth bi-annual meeting of the Advisory Committee. 28 proposals received. 11 activities funded to date.

An Evolving R&D Effort  We are seeing R&D encompassing current leading-edge detector technology that is of interest broadly for NP, HEP, Medical, etc.  Growing involvement by consortia of universities and national labs: Much work needs to be done on each class of detector technique to identify appropriate technologies through simulation, prototyping, etc. Such consortia are the first step toward building scientific collaborations that can successfully mount EIC experiments.  Several activities share common interests in specific technologies (e.g. GEMSs, Si PMs)  There is a healthy, growing overlap with related R&D efforts for RHIC, CEBAF, and HEP experiments. Looking ahead, we need to consider how best to focus these factors on the specific needs of an EIC program, optimizing the impact of available funds.

Early Emphasis on Simulation Tools Simulation studies to understand the specific technical requirements for EIC experiments: Maximize acceptance and efficiency for each golden measurement while minimizing machine backgrounds, and backgrounds from other physics processes. Software packages include Monte Carlo generators specially developed for e-p and e- A collisions at EIC energies. Detector simulation packages: impact of detector responses on physics observables… EicRoot framework, based on Fair Root Fast smearing generator Long-term support and maintenance of these programs, essential for the design and implementation of EIC detectors, requires a sustained effort. Plans are in progress.
