Outer Tracker Conceptual Design § 2 types of “p. T” modules § At intermediate radii, pixel-strip (PS) modules § At larger radii, strip-strip (2 S) modules § § 3 types of sensors § 2 S AC coupled 5 cm long strip sensor with 90 µm pitch § PS AC coupled 2. 5 cm long strip sensor with 100 µm pitch § PS DC coupled macro-pixel sensor 1. 5 mm long with 100 µm pitch § 320 µm thick n-in-p baseline sensors with deep diffusion 200 µm active thickness Binary readout chip to deal with substantially larger data volume due to increased channel count and inclusion of trigger information § “CBC” 130 nm CMOS § FE ASICs flip-chip bump-bonded § Powered with point-of-load DC-DC converters Director's Progress Review -- Outer Tracker K. Ecklund, 2015 September 17 6

Material compared to present tracker • • • Silicon & ASICS similar Barrel is integrated design; present tracker has two independent volumes DC-DC conversion and CO 2 cooling reduce material Overall attention to material in design: modules, routing of services Largest reduction in barrel-endcap region where services sit However, must remain vigilant as design progresses.
