Characterization of an ultra-stable monolithic cavity for ADV

Type of contract
Traineeship contract for a period of 4-6 months within the EGO Optics laboratory, funded by the EGO Consortium.

Description
The EGO Consortium (European Gravitational Observatory) is responsible for the operation of the detector and is also involved in the design and construction of Advanced Virgo. In particular, EGO will realize the input optics system for AdV.
In this frame, we need to study the properties of the Reference Cavity (RFC) that enters in the laser stabilization loop as long term reference. The RFC is an ultra stable, high finesse, monolithic cavity placed under vacuum just before the input of the interferometer.
The RFC is a 30 cm long triangular cavity made of ULE chosen for its excellent thermal stability. It has a finesse of about 30 000 and a visibility of 80%.
During this internship, we propose to make the full characterization of this cavity to check its compliance with AdV requirements. It would consist in measuring the losses and the finesse for different input polarizations. We also propose to measure the influence of some environmental noise on the cavity such as vibration by making some seismic noise injection. This will require locking a laser on the cavity using the Pound-Drever-Hall technique.

Requirements
Applicants should have a university degree in optics or physics. English required.

Non linear analysis for noise characterization for ADV

Type of contract
Traineeship contract for a period of 4-6 months within the Data and Noise Analysis group, funded by the EGO Consortium.

Description
The EGO Consortium (European Gravitational Observatory) is responsible for the operation of the detector and is also involved in the design and construction of Advanced Virgo and its noise characterization.
The preparation for noise detector analysis is fundamental also in this preliminary phase.
In this frame, we propose an internship to work on data analysis for the noise characterization of the future detector on real and simulated data.
In the past scientific runs we found non linear coupling in the interferometer which make the noise analysis difficult. It is important to develop and test new algorithms for the non linear analysis which will be used for Advanced Detectors characterization.
The work will be done on real data of past scientific runs where there was evidence of non linear coupling and on ad hoc simulated data.

Requirements
Applicants should have a university degree in astrophysics, physics or computer science with experience on signal processing or telecommunications engineering. English required.
