“…3. The differences in the curves arise from the module being operated in undepleted and over-depleted modes, where = 370 V. The noise occupancy as a function of the threshold is fit with an error function; the shape describes the distribution well with a minimal non-Gaussian tail in the noise spectrum [3]. The signalto-noise ratio yields values of 30 to 35 for a sensor bias voltage of 400 V [1].…”

“…In the barrel region, they are straight with 14 rectangular modules, whereas in the endcap region the geometry makes the modules differently sized and shaped. Drawings of a stave and a petal with their components are shown in Figure 5 [8,9]. The assembly is simplified for mass production, with the modules glued on a bus tape which is co-cured on a carbon core structure.…”

While the LHC at CERN is ramping up luminosity after the discovery of the Higgs Boson in the ATLAS and CMS experiments in 2012, upgrades to the LHC and experiments are planned. The major upgrade is foreseen for 2024, with a roughly tenfold increase in luminosity, resulting in corresponding increases in particle rates and radiation doses. In ATLAS the entire Inner Detector will be replaced for Phase-II running with an all-silicon system. This paper concentrates on the strip part. Its layout foresees low-mass and modular yet highly integrated double-sided structures for the barrel and forward region. The design features conceptually simple modules made from electronic hybrids glued directly onto the silicon. Modules will then be assembled on both sides of large carbon-core structures with integrated cooling and electrical services.

“…From the resulting S-curve, all characteristics of each channel, such as noise, are determined in a fit. The readout is done with the full testing setup [10]: the module is connected to HSIO ("High Speed Input Output") board developed by the ITk collaboration [11], and read out with a root program called SCTDAQ developed at Rutherford Appleton Laboratory (RAL) [12]. One can confirm the expected good correlation between the inter-strip capacitance and the noise for the different structures [13,14], which demonstrates that the inter-strip capacitance measurements, with all-neighbors considered, are a proper test to estimate the noise behavior of the different EPA layouts [15].…”

a b s t r a c t A proposal to fabricate large area strip sensors with integrated, or embedded, pitch adapters is presented for the End-cap part of the Inner Tracker in the ATLAS experiment. To implement the embedded pitch adapters, a second metal layer is used in the sensor fabrication, for signal routing to the ASICs. Sensors with different embedded pitch adapters have been fabricated in order to optimize the design and technology. Inter-strip capacitance, noise, pick-up, cross-talk, signal efficiency, and fabrication yield have been taken into account in their design and fabrication. Inter-strip capacitance tests taking into account all channel neighbors reveal the important differences between the various designs considered. These tests have been correlated with noise figures obtained in full assembled modules, showing that the tests performed on the bare sensors are a valid tool to estimate the final noise in the full module. The full modules have been subjected to test beam experiments in order to evaluate the incidence of cross-talk, pick-up, and signal loss. The detailed analysis shows no indication of cross-talk or pick-up as no additional hits can be observed in any channel not being hit by the beam above 170 mV threshold, and the signal in those channels is always below 1% of the signal recorded in the channel being hit, above 100 mV threshold. First results on irradiated mini-sensors with embedded pitch adapters do not show any change in the interstrip capacitance measurements with only the first neighbors connected.
