Info for Gemini users

Details

Ideally, proposed experiments should be based on one of layouts described under Gemini’s setups (below). Significant deviations from these layouts must be agreed with the Experimental Operations manager prior to submission.

 

Dual beam setup Long focus setup for gas target interactions Short focus setup for solid target interactions
The experimental access slot will be preceded by a set-up period to allow CLF staff to build up the optical layout and carry out diagnostic testing as far as possible in the time available. All non-standard diagnostics and potential hazards must be discussed and agreed with the Experimental Operations manager prior to proposal submission. Equipment that is brought to CLF by the user group must be delivered to site in good time, to ensure adequate time for safety assessments and integration into the experiment. To ensure reliability of the system, we may require up to 50% of a day each week, preferably Mondays, to carry out maintenance and optimise performance. All lost hours will be compensated by providing operational support during out-of-office hours.
The proposal application must be accompanied by a completed CLF experimental pack (below), which lists the requirements for laser parameters, Target Fabrication, experimental gases and diagnostics.
CLF experimental pack for principal investigators
At the end of the document, we request that you provide some details of the proposed experiment, with a sketch of the required beam and diagnostic layouts. This will be very useful for CLF staff, and will help them to understand the technicalities that might not be included in the scientific case because of lack of space.

FAQ

Who can apply to use the facility?

Researchers from universities, national labs and international institutions can all apply to use the facility. Experimental proposals must undergo a competitive peer review, where priority is given to experiments that advance fundamental science and technology. Industrial scientists can apply for peer review access in partnership with academics, or access the facility directly via the proprietary access mechanism. Please contact the Industrial Partnerships team [Link to Industry] for further information.

What experiments are typically performed there?

Laser driven particle acceleration, ultrafast X-ray generation, laser plasma interactions, warm dense matter studies, radiation pressure and relativistic plasma physics, astrophysical simulations.

What are the main capabilities?

Dual beam operation with 40fs pulses of up to 15J. Intensities exceeding 1021W/cm2, high temporal and spatial contrast.

Are there any costs involved in using the facility?

If the proposal is accepted, academic users are often granted access free of charge. Industrial or commercial users may be subject to access fees.

How long does it take to get beam time after submitting a proposal?

There are biannual deadlines for proposal submission, after which there is a review period which can take between two to three months. Experiments are then scheduled to take place between six to 12 months after having been selected.

Are there any training or support services for new users?

Yes, there is support through multiple planning meetings ahead of the experiment, hands on support throughout the experiment, and laser safety training for the Gemini users.
