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.

First waveforms in NEW

NEW is alive and running! Here you can see a beautiful waveform of an alpha particle releasing its energy in argon gas at 5 bar of pressure. The large peak at 600 microsecond is the secondary scintillation signal, preceded few tens of microseconds before by the primary one. The small peaks at lower times are believed to be electrons coming from the rubidium source decay, which we have inserted in the gas as a calibration tool.

Stay tuned for the upcoming xenon run!

Cryo-recovery system completed

The last piece of the NEXT cryo-recovery system is installed in Canfranc, a protection against splashes which allows us to operate safely with xenon.
