Seminar: From neutrinos to large clusters

Alfredo Galindo-Uribarri, Oak Ridge National Laboratory / University of Tennessee, Knoxville.


HRIBF was the premier ISOL facility for the production of high quality and purity radioactive ion beams until April 2012; since then we are currently going through a transitional period.

Utilizing infrastructure associated with HRIBF has allowed us to perform other class of experiments such as developing analytical techniques to detect impurity trace levels of uranium and thorium in the high purity materials required for ultra low background experiments (e.g. neutrinoless double beta decay).

We have done an experimental study on the production of large negative ion copper clusters. We further explored the potential application of copper clusters, utilizing the energy-and-mass-selected copper cluster to create nanoscale pores in a layer of graphene.

I will also discuss our efforts using Accelerator Mass Spectroscopy in the search for doubly charged negative atomic ions.

The Physics Division at ORNL

is exploring key opportunities for neutrino physics and supporting the formation of an experimental program at the intersection of particle, nuclear, and astrophysics. 

The Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) of ORNL are two very powerful neutrino sources that open new physics opportunities.

I will review some of the current activities taking place at ORNL including The Precision Oscillation and Spectrum Experiment, or PROSPECT, which is soon to be deployed at HFIR.
