Peter Sonderegger, in memoriam

Peter was the first supervisor of J.J. Gomez-Cadenas when he worked as a student at CERN. He was a great physicist, mentor and friend.

Run II results

The first results of energy resolution and tracking for the Run II of NEW are here! We get an energy resolution of 5.5% FWHM at the energy of the krypton peak and very nice tracks of electron-positron pairs, which mimic the neutrinoless double beta decay signal, featuring two nice blobs of energy at the end!





First NEW results

In the recent NEXT Collaboration Meeting the first results from NEW have been presented! The detector is in very good shape, the sensors are working with very similar performance and the first spectra and tracks have been obtained! A warm thank you to all the people who have made possible this great achievement with a lot of effort and struggle!

Here you can see one of our first reconstructed electron tracks, where the higher energy deposition at the end of the trajectory is clearly visible.

Stay tuned for more!

Krypton waveforms in the first NEW xenon run

The NEXT experiment has achieved a major milestone with the start of the xenon run in the NEW detector. The program foresees an initial calibration run with krypton followed by further calibrations with other radioactive sources.

Here you can see an example of krypton signals observed today, seen by the silicon photomultipliers (SiPM) of the tracking plane and by the photomultipliers (PMT) of the energy plane.
