Dear participant,

We hope that the conference has satisfied you, and has given you pleasant moments of convivial and scientific exchanges with your peers. We also hope you had a good trip home.

On behalf of the organizing committee we thank you for your participation and your involvement in this congress, we hope it has satisfied your expectations.

The local organization captured many photos during the conference. You will be able to download them via the link: TRACER 8 Pictures.

Participants’ presentations and posters are available for download via TRACER 8 Files. An email regarding your authorization or not of diffusion was sent to you at the beginning of the week. We will get back to you with the access code soon.

Once again, thank you very much and look forward to meeting you in the next Tracer conference.

Best regards

The Organizing Committee

Welcome to the 8^th International Conference on Tracers and Tracing Methods!
