Type of contract

Traineeship contract for a period of 2 months within the EGO Optics laboratory in the Interferometer Technology Department.


The Virgo Interferometer is the most sensitive gravitational-wave (GW) detector in Europe. It is a 3km laser interferometer located near Pisa, Italy. The European Gravitational Observatory (EGO, www.ego-gw.it) is the laboratory hosting and operating Virgo. Since the first GW detection in 2015, Virgo and the two LIGO interferometers in the USA have jointly detected several GW signals, opening the new era of GW astronomy.

A 1-year-long observation run (“O3”) was concluded in March 2020. The next observation run should start mid-2022: in the meantime, all detectors are being upgraded and work is ongoing to improve their performance, building on experience gained during the O3 run.

One of the most important upgrades of Advanced Virgo before next observing run consists in the integration of a frequency dependent squeezing for a broadband quantum noise reduction in the detector sensitivity.

In parallel, Virgo researchers are also developing an alternative and more compact setup capable to produce frequency dependent squeezing by exploiting the EPR (Einstein Podolsky Rosen) quantum entanglement. This tabletop experiment is currently under design and it will be soon installed in the R&D squeezing lab at EGO.

During this internship, the student will participate to the installation and will be in charge to align and test the optical elements that will be installed on the bench.

This will include measurements of the performances of a Mach Zehnder interferometer, a Second Harmonic Generation cavity, an OPO cavity, two balanced Homodyne Detectors and possibly measure squeezing.

Participation to the possible publication of the results will be part of the internship work.


Applicants should be at the end of their first year of study in optics or physics. English required. Good attitude to experimental work is mandatory, familiarity with control systems and related hardware/software will be an asset. European citizenship, no criminal convictions.

Place of work

EGO – European Gravitational Observatory – Via Edoardo Amaldi cap 56021 Loc. Santo Stefano a Macerata – Cascina (Pisa) Italy. Given the lack of public transport to reach EGO, a driving license and a personal vehicle are strongly recommended.

Further information

For the whole duration of the traineeship, EGO will pay a gross monthly wage of 500,00 euro and offer the lunch service at its canteen during working days to the student.
