On 20 February, a book entitled Les dentelles noires de l’Etna was published, written by Jean Lautier-Gaud, a member of the LTE staff. In it, he recounts an experiment carried out by an LTE research team.

In this novel, Jean Lautier-Gaud recounts the scientific and human adventure in which he participated to install a quantum gravimeter at ‘Dentelles noires’, the observatory station located closest to the craters of Mount Etna. This sensor, based on the work of the LTE’s Atomic Interferometry and Inertial Sensors team, is used to study and monitor volcanoes. The author discusses the project and the novel.

« My thesis with Arnaud Landragin at LTE focused on developing a compact quantum gravimeter for field measurements within the Atomic Interferometry and Inertial Sensors team. In 2014, we published a major result paving the way for the use of these instruments outside laboratories.

The technologies developed by the team were transferred by the CNRS to the start-up Muquans, which turned them into a commercial product, enabling one of these sensors to be installed on Mount Etna, an expedition in which I personally took part.

I ended up writing a book on the subject, in which I revisit the human and scientific adventure of climbing. Popular science on the subjects of metrology, quantum sensors and geophysics features prominently in the book. The novel was released on 20 February in bookshops, published by Transboréal.

Today, the deployment of quantum gravimeters in the field continues, notably as part of the EQUIP-G project, supported by the CNRS and led by the LTE. »
