Service des Photons Atomes et Molécules

  Le SPAM est un Laboratoire de Recherche au sein de l'Iramis (Institut Rayonnement Matière de Saclay) rattaché à la Direction des Sciences de la Matière du CEA, dédié à la recherche fondamentale dans le domaine de l’interaction photons-matière et s’ouvrant également sur de nombreuses applications.

Le SPAM est membre du RTRA « Triangle de la Physique », du LABEX PALM et de l’IDEX Paris-Saclay. Le SPAM accueille une plateforme laser femtoseconde (SLIC) membre du réseau Européen LASERLAB et est impliqué dans 2 EQUIPEX : CILEX et ATTOLAB.

: IN PROGRESS
: The Physic at High Intensity (PHI) group of DSM/DRECAM studies the behaviour of solid density plasmas submitted to ultra-short (<60fs) and ultra-intense (1018-1019W/cm2) laser pulses.
Betatron radiation as a powerfull diagnostic for laser-plasma acceleration : Among the various parameters involved in laser-plasma acceleration mechanisms, the electrons themselves can be collected and studied.
Brief introduction to ion acceleration : Undoubtedly, the acceleration of charged particles has been one of the most active research fields in the physics of laser-matter interaction all along the last ten years.
