[Tipp2014] Certificate of contributions to TIPP2014

Dear Sir/Madam,

To justify my trip, I need a certificate signed by the Conference's Secretary where it appears the title of my contributions to TIPP 2014:

ID 41: Characterization of a Spherical Proportional Counter in argon-based mixtures.

ID 103: Lowering the background level and the energy threshold of Micromegas x-ray detectors for axion searches.

ID 199: Axion helioscopes update: the status of CAST & IAXO

Could you provide me this certificate, please? A pdf file would be enough.

Many thanks in advance.

Yours faithfully,

Francisco Iguaz
