    Abstract. In this paper, we consider the star operations for (graded) affine Hecke algebras which preserve certain natural filtrations. We show that, up to inner conjugation, there are only two such star operations for the graded Hecke algebra: the first, denoted ⋆, corresponds to the usual star operation from reductive p-adic groups, and the second, denoted • can be regarded as the analogue of the compact star operation of a real group considered by [ALTV]. We explain how the star operation • appears naturally in the Iwahori- spherical setting of p-adic groups via the endomorphism algebras of Bernstein projectives. We also prove certain results about the signature of •-invariant forms and, in particular, about •-unitary simple modules.

    Abstract The semiconductor tracker (SCT) is one of the tracking systems for charged particles in the ATLAS detector. It consists of 4088 silicon strip sensor modules.During Run 2 (2015–2018) the Large Hadron Collider delivered an integrated luminosity of 156 fb -1 to the ATLAS experiment at a centre-of-mass proton-proton collision energy of 13 TeV. The instantaneous luminosity and pile-up conditions were far in excess of those assumed in the original design of the SCT detector.Due to improvements to the data acquisition system, the SCT operated stably throughout Run 2.It was available for 99.9% of the integrated luminosity and achieved a data-quality efficiency of 99.85%.Detailed studies have been made of the leakage current in SCT modules and the evolution of the full depletion voltage, which are used to study the impact of radiation damage to the modules.
