Abstract: Emulsion detectors feature an unbeatable position resolution down to tens of nanometers for charged particles, allowing a 3D reconstruction of particle trajectories. The Laboratory for High Energy Physics of the University of Bern is one of the few laboratories in the world with an access to the core of the techniques.
I will report a general review on the emulsion detectors and their applications. Then, I will focus on the ongoing challenging R&D activity on emulsions for the AEgIS experiment at CERN aiming at the first measurement of the gravitational acceleration on antimatter. In AEgIS, the data rate from an automatic emulsion scanning system will be of the order of 1 GByte/s, which obviously requires a high performance computing solution. Recent achievements by GPUs (Graphic Processing Units) for processing will be also reported.
Bio: I played an essential role for the design and construction of the emulsion detectors for the OPERA experiment, and in 2008 I got my PhD in science at the Nagoya University in Japan. In 2008 I moved to the Laboratory for High Energy Physics (LHEP) of the University of Bern as a post-doc and became a senior staff in 2011.
In addition to the neutrino oscillation studies in OPERA and T2K, I conducted an R&D activity on emulsion hardware and I proposed emulsion detectors for several applications in the fields of medicine, geology and for the diagnosis of accelerator beam. A further intensive activity concerns the development of a fast emulsion scanning system using GPUs for the AEgIS experiment, a work that I presented at the GPU Technology Conference 2014 in San Jose on 24-27 Mar. This gave me the opportunity to be here today.
