PI: Dr Joanna Renshaw
The PANAMA facility, based in the Scottish Centre for the Application of Plasma Accelerators (SCAPA) will provide state-of-the-art characterization and testing capabilities for nuclear materials from across the nuclear sector, from new build and fuel development and manufacture, to decommissioning, waste management and geological disposal.

Capabilities being developed at PANAMA include:

  • X-ray and γ-ray Computed Tomography (X-CT/γ-CT)
  • γ-radiography imaging
  • X-ray Absorption Spectroscopy (XAS)
  • X-ray Diffraction
  • Time-resolved diffraction & spectroscopy
  • Radiation damage (particle beams, including protons and 4He ions)
  • Pump-probe on radiation damage combining particle beams with diffraction / spectroscopy / imaging.

Laser-driven plasma accelerators derive their energy from a high intensity laser (generally a Ti:sapphire laser) that irradiates a low density plasma target with femtosecond light pulses. The light pulses produce a density wake in plasma thus separating the charge to produce accelerating fields 1000 times stronger than possible in conventional accelerators. The resulting self-injected electrons form ultra-short duration bunches, which can directly produce THz radiation, X-rays or gamma rays up to 10 MeV or through interacting with a secondary target or counter-propagating laser beam produce 100s MeV photons. Radiation produced in laser-plasma interactions include: electrons, muons, protons, neutrons and light ion beams, and electromagnetic radiation pulses from the IR to gamma rays. 

The SCAPA facility uses two state of-the-art Ti:sapphire lasers: a 40 TW (1.4 J, 35 fs; at 10 Hz) and a 350 TW (8.75 J, 25 fs; at 5 Hz) system, to generate: 

Radiation pulses:
  • High brightness THz and infra-red radiation; 
  • Partially coherent betatron (plasma wiggler) radiation in the X-ray to γ-ray (10s of MeV) range;
  • Coherent radiation from a free-electron laser (FEL) in the VUV- X-ray (sub-nm) range.
Particle beams:
  • Monoenergetic electron beams of energy 100 MeV – 4 GeV;
  • Proton and light ion beams of energy up to 100 MeV/c.

At the PANAMA beamline, these SCAPA capabilities will be exploited for advanced materials characterization. The high energy range of the produced X- and γ-rays (100s of keV to MeV) can penetrate very dense (or very large) materials for detailed imaging of such materials. Additionally, the ultrashort duration of the high intensity hard X-ray pulses (e.g. 7-20 keV) can be utilized for time-resolved diffraction and spectroscopy at ultrashort timescales. Perhaps most important, the flexibility of the X- and γ-rays produced and the possibility to (nearly) simultaneously produce particle beams enables combining imaging, spectroscopy or diffraction with radiation damage on the same sample to enable in-situ real-time observations of the precise mechanism of damage relevant to the nuclear energy sectors, including structural materials, waste matrices, and cladding. 

A new dedicated active lab will also enable safe manipulations of radioactive samples, including subsequent analysis at the PANAMA beamline.
 

PANAMA is currently scheduled to be available for access by external users from early 2021 (for the X-CT in the first instance). Please do reach out to the PANAMA team, to start discussing access, at any point.

 

 

NNUF funded user access scheme for PANAMA

As a first step, please email pieter.bots@strath.ac.uk to contact PANAMA for a discussion about the practical feasibility of your proposed research project. Then, you will need to complete a simple NNUF application form. When doing so, please upload an email exchange between you and a member of staff at PANAMA, confirming the feasibility of your proposed research. Please see the access page of this website for more detail about the NNUF funded user access scheme.
