                          Acknowledgment
 

The science programme on LISA has so far included:


+    dynamics of energy redistribution in solid water


+    infrared photo-desorption of small molecules form ice surfaces


+    surface diffusion on ice surfaces

Flexibility to couple instruments    (e.g. FTIR + QMS)

  Rotation + XYZ stages for sample manipulation
 
 
Future for AstroScience at FELIX

Selective IR/THz experiments at FELs
are needed to understand:


The nature of IR/THz modes
Dynamics in ices
 
Energy relaxation in ices
 Diffusion, reaction, desorption
  The physics and chemistry of the interstellar medium
 
Funding


The existing apparatus LISA largely meets constraints of the laboratory astrochemistry community who are interested in thin icy films. Potential upgrades include:

5 keV electron gun
 
Additional independent dosing line(s)
 
Single trigger process for sample illumination and shot-by-shot pulse energy measurement and recording near sample.
 
Improved QMS (pulse counting rather than analogue) or TOF

If you have other needs then please contact Sergio Ioppolo.



 
New collaborations from AstroScience and Catalysis are Welcome

Financial support is available from:
FLUENCE (for UK users new to FELIX)
Laserlab Europe & CaLIPSOplus (for EU users)
