2. Expected LOI contents:final wording of IDAG additional requests • Detector optimization: identification of the major parameters which drive the totaldetector cost and its sensitivity to variationsof these parameters. • Plans for getting the necessary R&D results totransform the design concept into a well-defined detector proposal. • Conceptual design and implementation ofthe support structures and the dead zones in the detector simulation. • Sensitivity of different detector components to machine background in the context of the beam parameter space considered in the RDR. • Calibration and alignment schemes. • Estimates of overall size, weight, andrequirements for crane coverage and shielding. • Push-pull ability with respect to technicalaspects (assembly areas needed, detector transport and connections, time scale) and maintaining the detector performance for a stable and time-efficient operation. • A statement about energy coverage,identifying the deterioration of theperformance at energies up to 1 TeVand the consequent detector upgrades.

3. Proposal of Jean-Claude, Based on a TOTAL of 12 pages • Introduction on PFA based calorimetry (1 page) • suppose the names of the mail are the good one (Kiyotomo, Felix, Imad and myself) • I would see here the R&D needed and the CALICE organization per project (who is doing what) and the expected test beam plan (Is it possible for you Felix,(as spokesperson of CALICE) to write a first draft of that part) • Mechanics (3 pages ) Resp: including (as Felix said), structure and specificity of each technology option • For ECAL Si and Scint. : Marc Anduze • For AHCAL : • For DHCAL : • VFE and FE (DIF) (1 page) Resp: • For ECAL (both Si and Scint., if Kiyotomo agrees) : Julien, Remi and Bart • For AHCAL : Ludovic and Mathias • For DHCAL : ??? (not Julie, since LAPP is not in ILD ) please Imad give us a name • DAQ (1 page) Resp Valeria (for LDA-ODR) , Vincent (for DHCAL) • TECHNOLOGY OPTIONS(1.5 page per option) • ECAL silicon – tungsten : Resp: Remi , Roman (1page, essentially on silicon wafers, long slab ASU) • ECAL scintillator – tungsten : Resp : Tohru, Kiyotomo, Satoru • HCAL sctinillator : Resp • DHCAL gas : Resp
