Workplace : ORSAY
Date of publication : Friday, November 13, 2020
Type of Contract : FTC Scientist
Contract Period : 24 months
Expected date of employment : 1 February 2021
Proportion of work : Full time
Remuneration : Between 2728€ and 3145€ gross per month depending on experience.
Desired level of education : PhD
Experience required : Indifferent


The postdoctoral researcher will be part of the gravitational wave team (responsible Nicolas Leroy, leroy@lal.in2p3.fr) within the astrophysics, astroparticle and cosmology department (A2C). She/He will work on experimental setup to generate frequency dependent squeezing. This R&D is part of the Advanced Virgo project to improve its sensitivity.


The postdoctoral fellow will work on:
- Improving the present system available in the lab to generate squeezed light (frequency independent)
- Testing the system under vacuum (10-6 mbar)
- Coupling the source to a 50m filtering cavity (already available)
- Characterizing the whole system
- Preparing next step which will use coupled filter cavities
- Publishing the different steps


Training and/or professional experience in realization of optical system is required. Training in feedback control (PDH, …) is desirable. Having knowledge in nonlinear optic could be helpful.
We will study candidature even just after a PhD.
The postdoctoral fellow will need to work collaboratively with a team including researchers and engineers. She/He will need also aptitude to work alone on specific subjects. Work will .
be done inside an international collaboration with short periods abroad (mainly Italy and Japan).

Work Context

The Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a UMR under the supervision of the CNRS (IN2P3), the University of Paris-Saclay and the University of Paris is located on the campus of the University of Paris -Saclay in Orsay. The laboratory is located on the campus of the Université Paris-Sud, Université Paris-Saclay in Orsay. The campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
IJCLab was born in 2020 from the merger of five units (CSNSM, IMNC, IPN, LAL, LPT). The staff is made up of nearly 560 permanent (340 engineers, technicians and administrators and 220 researchers and teacher-researchers) and approximately 200 non-permanent including 120 doctoral students. The research themes of the laboratory are nuclear physics, high energy physics, theoretical physics, astroparticles, astrophysics and cosmology, particle accelerators, energy and the environment and health. IJCLab has very significant technical capacities (around 280 IT) in all the major fields required to design, develop / implement the experimental devices necessary for its scientific activity, as well as the design, development and use of instruments. .
The work will be done within the framework of international collaboration called Qfilter between France and Japan. In France it includes IP2I (Lyon) and LKB (Paris) laboratories.

Constraints and risks

Short periods of travel within France and abroad should be expected
Work in clean rooms and class 4 lasers
