The DIPC-Workshop on "Single Atom Ba Tagging" (SABAT 2018) will be held at the "Donostia International Physics Center" (DIPC), Donostia-San Sebastian, on July 9-10, 2018. The aim of the workshop is to review the experimental techniques needed to achieved single-atom tagging in Xe-137 double beta decays produced in a gas xenon TPC.  Currently, the most promising way to achieve Ba++ tagging is the use of Single Molecule Fluorescence Imaging. The notion, was proposed by Dave Nygren in 2017, and a first proof of concept has been carried out by the NEXT collaboration in 2018. Further progress requires a multi-disciplinary approach involving several fields.


Topics include:

* Applying Single Molecule Fluorescence Imaging to single-Ba++ ion tagging.

* Proof of principle of SMFI technique for Ba++ tagging.

* Developments of dyes for SMFI Ba++ tagging.

* SMFI Ba++ tagging in vacuum.  Molecule layers and microscopy.

* SMFI Ba++ tagging in high pressure gas. 

* Use of nano-technology to amplify signal.

* Development of Ba++ sources.

* Development of RF ``carpets’’ for Ba++ collection.

* Implementation in HPXe chambers (e.g, NEXT detector).


In the spirit of DIPC Workshops, SABAT would like to provide a friendly atmosphere to foster discussions and collaborations between leading scientists working in the various fields involved.
