WP9: TA4 – Trans-national Access to CLIO
Provision of access to the following infrastructure(s): CLIO
Description of the infrastructure
The Centre Laser Infrarouge d’Orsay (CLIO) is a light source operated as a user facility. CLIO is part of the Laboratoire de Chimie Physique (LCP) of the Université Paris-Sud which operates also the 9 MeV accelerator ELYSE dedicated to photo-chemical investigations to form a service platform delivering electrons.
The CLIO infrared laser facility is a linac based free-electron laser delivering tunable and powerful infrared radiation in short pulses. Its tuning range spans from 3 to 150 μm. A new undulator is under development for further extension toward the THz spectral range. Complementary, Optical Parametric Oscillator (OPO) systems are also available at the CLIO facility, backing up the FEL for short wavelength operation (2-8 μm) and providing tunable visible light for non-linear experiment of SFG (sum frequency generation) or kinetics involving pump-probe operation with different colours.
The time structure of CLIO is composed of 10 μs long trains of pulses (“micropulse”), each “micropulse” being usually a few picoseconds long. In addition, the two-colour-operation of CLIO is almost unique in the world:
- Spectral range: 3 to 150µm
- Polarisation: linear
- Relative spectral weight: 0.2 to 2%
- Macropulse lenght: 1 to 9µs (tunable)
- Micropulse: 0.3 to 5ps
- Peak Power: 10 to 300MW
- Average power: 2 to 0.5 W (25Hz, 16ns micropulse distance)
- Two-colour operation: tested up to 30µm
Most of the permanent beamlines (SFG, IRMPD, AFMIR) are operated by researchers (beam line scientists) who support external users during their experiment. The general purpose room is managed by the FEL team, which is in charge of users bringing their own set-up.

|Services currently offered by the infrastructure||The optical beam is brought to eight user laboratories. five of which are available for users :
Modality of access & application procedure
|Modality of access||Calls for proposal:
|Outreach to new users||Beamline data sheets are also available on wayforlight.eu (Find more information here: infrastructure CLIO@wayforlight.eu and CLIO email@example.com)
Outreach activities to attract new users to CLIO will be harmonised with “WP2 – NA1 – User tools for access and data management” as well as “WP3 – NA2 – Dissemination & Training”, respectively.
|Review procedure||Project proposals re submitted to a peer-review panel, which selects the projects on the exclusive criterion of scientific merit giving priority to users coming from countries without infrared FEL.
The Program Committee is composed of four external scientific experts.
