José Maneira

Professor (FCUL) / Researcher ( LIP Lisboa )





I graduated in Physics at Faculdade de Ciências da Universidade de Lisboa (FCUL) in 1995, and started my Master's then. I did the Master's thesis in Neutrino Physics, working in Italy, at the Istituto Nazionale di Fisica Nucleare (INFN) Milano. My supervisors were Amélia Maio (FCUL), Gianpaolo Bellini and Emanuela Meroni (INFN), and I worked on the simulations for the design of the Borexino solar neutrino experiment, at the Gran Sasso national labs in Italy (LNGS).

I followed it for a PhD with further work on Borexino at Milano, now on the design and construction of various calibration systems. My supervisors were Amélia Maio (FCUL), Gianpaolo Bellini and Sandra Malvezzi (INFN), and I discussed the thesis at FCUL in January 2002.

For my first Post-Doc I continued on solar neutrino physics, at Queen's University, in Kingston (Canada). I worked in the Sudbury Neutrino Observatory (SNO), under the supervision of Aksel Hallin and Mark Chen, mainly on the optical calibration of the SNO detector, but also on the neutrino oscillation analysis. I also worked on double-beta-decay sensitivity studies, and signed the 2004 SNO+ LOI to SNOLAB.

Wanting to expand my Particle Physics range, I started working in High Energy Physics at the ATLAS experiment, at the Large Hadron Collider (LHC), CERN, when I moved back to Portugal in late 2004. My main activities were in the commissioning of the TileCal hadronic calorimeter, developing a calo-standalone reconstruction algorithm for cosmic muons. When the LHC turned on, my main Physics analysis was the search for the Higgs to bb decay in associated production with a vector boson. I co-supervised two PhD thesis on these two subjects.

At the same time, with the support of Amélia Maio and a dedicated FCT project grant, I continued to work on SNO, starting a small group at LIP, focusing on optical calibration and neutrino oscillation analysis, the main subjects of a PhD thesis I also co-supervised. The group expanded when activity in SNO+ increased, and 3 LIP people participated in the first SNO+ collaboration meeting in Kingston in 2007. With the long-standing LIP expertise on optical fibers, we proposed, designed and built a large part of the SNO+ PMT calibration system, based on >100 optical fibers mounted on the detector (installation finished in 2016). With the technical skills of the LIP mechanical workshop and detector labs, in Coimbra, we adapted the SNO design to SNO+, and built the mechanical apparatus to insert calibration sources inside SNO+.

The SNO+ group has further expanded since 2013, SNO+ has started taking data, and my main current research focus is on the commissining of SNO+ with the preliminary water data, and preparing the upcoming measurements of double beta decay with Tellurium-loaded liquid scintillator.
