Characterization of CHRAC for thermal compensation of optics surface defects

European Gravitational Observatory

Internship 5 months Cascina, Italy

Uploaded 23 Dec 2018

Job Description

The Virgo interferometer is the most sensitive gravitational-wave detector in Europe. To achieve the required sensitivity, adaptive optics are used to maximise the smoothness of the mirrors. The basic principle of thermal compensation consists of changing the mirror shape by heating it up in specific points, correcting the unwanted defects. A new system of thermal compensation, which has been developed in collaboration between the Optics Group and the Virgo Pisa Group is the Central Heating Residual Aberration Correction (CHRAC).

The student will be in charge of setting up the CHRAC and carrying out some tests to validate its functioning. She/he will have the opportunity to work on various aspects of the fields: mainly optics, but also to collaborate with the electronics and mechanics groups at EGO. 

For the whole duration of the internship, EGO will pay a gross monthly wage of 500,00 euro, the accommodation and the lunch at its canteen during working days.

Interested candidates are invited to fill in the Internship Application Form and send it, together with the CV, to [email protected]

Person Specification

Applicants should be in their last years of study in optics or physics. The work will be at a level of Master thesis (equivalent to thesis for "laurea specialistica" in Italian). 

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.
