To cope with the occupancy and radiation environment expected at the High-Luminosity LHC, the ATLAS experiment will replace its Inner Detector with an all-silicon Inner Tracker (ITk), containing pixel and strip subsystems. The strip subsystem will be built from modules, consisting of one or two n+-in-p silicon sensor(s), one or two PCB hybrid(s) containing the front-end read-out electronics, and one powerboard with high voltage, low voltage, and monitoring electronics. The sensors in the central barrel region of the detector will use a simple rectangular geometry, while those in the forward end-cap regions will use a radial geometry with a built-in stereo angle. To validate the expected performance of the ITk strip detector, a series of testbeam campaigns has been performed over several years at the DESY-II testbeam facility. Tracking was provided by EUDET telescopes, consisting of six Mimosa26 pixel planes. An additional FE-I4 pixel plane was used to provide sufficient timing resolution for the telescope. In the years 2021-2022, the focus of testbeam campaigns has been on assessing module performance post-irradiation, using the final production versions of the sensors, and most recent versions of front-end electronics. Three modules of differing geometry were built from irradiated components; a barrel SS, an end-cap R0, and an end-cap R5 type. With the R5 campaign also being the first time a "split" module design was tested at a testbeam (two sensors sharing FE electronics). Measurements of the collected charge, detection efficiency, and noise occupancy were performed on all tested modules, as well as of the tracking performance in various sensor regions. The results give confidence in the operability of the detector across its lifetime."The measurements leading to these results have been performed at the Test Beam Facility at DESY Hamburg (Germany), a member of the Helmholtz Association (HGF)".

The CLIC Tracker Detector (CLICTD) is a monolithic pixel sensor. It is fabricated in a 180 nm CMOS imaging process, modified with an additional deep low-dose n-type implant to obtain full lateral depletion. The sensor features a small collection diode, which is essential for achieving a low input capacitance. The CLICTD sensor was designed as a technology demonstrator in the context of the tracking detector studies for the Compact Linear Collider (CLIC). Its design characteristics are of broad interest beyond CLIC, for HL-LHC tracking detector upgrades. It is produced in two different pixel flavours: one with a continuous deep n-type implant, and one with a segmented n-type implant to ensure fast charge collection. The pixel matrix consists of 16 × 128 detection channels measuring 300 µm × 30 µm. Each detection channel is segmented into eight sub-pixels to reduce the amount of digital circuity while maintaining a small collection electrode pitch. This paper presents the characterisation results of the CLICTD sensor in a particle beam. The different pixel flavours are compared in detail by using the simultaneous time-over-threshold and time-of-arrival measurement functionalities. Most notably, a time resolution down to (5.8 ± 0.1) ns and a spatial resolution down to (4.6 ± 0.2) µm are measured. The hit detection efficiency is found to be well above 99.7 % for thresholds of the order of several hundred electrons.
