The upgrade of the ALICE TPC with GEMs and continuous readout
/ ALICE TPC Collaboration
The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we describe the design of new readout chambers and front-end electronics, which are driven by the goals of the experiment. [...]

SAMPA Chip: the New 32 Channels ASIC for the ALICE TPC and MCH Upgrades
/ Adolfsson, J (Lund U.) ; Pabon, A Ayala (Sao Paulo U.) ; Bregant, M (Sao Paulo U.) ; Britton, C (Oak Ridge) ; Brulin, G (Orsay, IPN) ; Carvalho, D (Sao Paulo U.) ; Chambert, V (Orsay, IPN) ; Chinellato, D (Campinas State U.) ; Espagnon, B (Orsay, IPN) ; Herrera, H D Hernandez (Sao Paulo U.) et al.
This paper presents the test results of the second prototype of SAMPA, the ASIC designed for the upgrade of read-out front end electronics of the ALICE Time Projection Chamber (TPC) and Muon Chamber (MCH). SAMPA is made in a 130 nm CMOS technology with 1.25 V nominal voltage supply and provides 32 channels, with selectable input polarity, and three possible combinations of shaping time and sensitivity.

Ctr.) ; Albrecht, T (Karlsruhe U., EKP) ; Alemany-Fernandez, R (CERN) ; Allmendinger, T (Karlsruhe U., EKP) ; Allport, P P (Liverpool U.) ; Amaldi, U (INFN, Milan Bicocca ; Milan Bicocca U.) ; Amapane, N (INFN, Turin ; Turin U.) et al.
/DELPHI
The hadronic part of the electron structure function F2e has been measured for the first time, using e+e− data collected by the DELPHI experiment at LEP, at centre-of-mass energies of s=91.2–209.5 GeV . The data analysis is simpler than that of the measurement of the photon structure function. [...]
