This paper presents the SAMPA, an ASIC designed for the upgrade of read-out front end electronics of the ALICE Time Projection Chamber (TPC) and Muon Chambers (MCH). SAMPA is made in a 130 nm CMOS technology with 1.25 V nominal voltage supply and includes 32 channels, with selectable input polarity, and five possible combinations of shaping time and sensitivity.

/ALICE
With the continuous scaling of the CMOS technology, the CMOS circuits are considered to be more tolerant to Single event Latchup (SEL) effects due to the reduction in the supply voltages. This paper reports the results from SEL testing performed on the first two prototypes for the new readout ASIC (SAMPA). [...]

Neutron-induced fission cross section of (nat)Pb and (209)Bi from threshold to 1 GeV: An improved parametrization
/ Tarrio, D (Santiago de Compostela U.) ; Tassan-Got, L (Orsay, IPN) ; Audouin, L (Orsay, IPN) ; Berthier, B (Orsay, IPN) ; Duran, I (Santiago de Compostela U.) ; Ferrant, L (Orsay, IPN) ; Isaev, S (Orsay, IPN) ; Le Naour, C (Orsay, IPN) ; Paradela, C (Santiago de Compostela U.) ; Stephan, C (Orsay, IPN) et al.
Neutron-induced fission cross sections for (nat)Pb and (209)Bi were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n\_TOF) facility. The experiment, using neutrons from threshold up to 1 GeV, provides the first results for these nuclei above 200 MeV. [...]

Pygmy Gamow-Teller resonance in the N=50 region: New evidence from staggering of β -delayed neutron-emission probabilities
/ Verney, D (Orsay, IPN) ; Testov, D (Orsay, IPN ; Dubna, JINR) ; Ibrahim, F (Orsay, IPN) ; Penionzhkevich, Yu (Dubna, JINR ; Moscow Phys. Eng. Inst.) ; Roussière, B (Orsay, IPN) ; Smirnov, V (Dubna, JINR) ; Didierjean, F (Strasbourg, IPHC) ; Flanagan, K (U. Manchester) ; Franchoo, S (Orsay, IPN) ; Kuznetsova, E (Dubna, JINR) et al.
We report on the β-delayed neutron emission probability (P1n) measurements of the Ga82,83,84 (N=51,52,53) precursors performed in one single experiment using the He3 neutron-counter TETRA at the ALTO facility in Orsay. Altogether our results for the three A=82,83, and 84 Ga precursors point towards a sizable P1n staggering in the N=50 region, similar to the one already observed just after the N=28 shell closure in the K isotopes chain, hinting at a similar mechanism.
