Christophe Blondel and Cyril Drag join LPP

Toutes les versions de cet article : [English] [français]

Christophe Blondel and Cyril Drag, respectively research director and research fellow (HDR) at the CNRS, formerly at the Aimé-Cotton laboratory (UMR CNRS 9188 in Orsay), officially joined the LPP on October 1, 2017. Since 2013, their team has been coordinating the SiPhoRE ANR project to demonstrate the interest and feasibility of magnetically controlled fusion of photodetached D0 injectors [1] (also supported by Eurofusion through FR-FCM). Since 2015, they have been collaborating with Olivier Guaitella and Jean-Paul Booth on laser diagnostic experiments in plasmas, during which they have incidentally found a way (reflexes of spectroscopists not extinguished !) to swallow the spectrum of atomic oxygen levels and measure an isotopic displacement that was previously only known by calculation [2]. Their installation in Palaiseau will make it possible to extend this collaboration to other LPP teams.
