Experiments on D retention were performed at temperatures up to 400°C.<ref>F.L. Tabarés et al. ''Studies of Plasma-Lithium Interactions in TJ-II''. IAEA 2012. P5/36</ref> | |||
Also, biasing of the LLL respect to the plasma and respect to he C limiter in C3 were carried out.<ref>E. Oyarzabal et al. Proc 17<sup>th</sup> ISHW Padova, Sept 2013.</ref> | |||
Insertion of the LLL up to 3 cm into the edge was possible without any apparent damage. | |||
Biasing of the LLL to positive voltages led to improved energy and particle confinement in ECRH plasmas. | |||

In 2014, a second LLL unit has been installed in C3 to replace the former C limiter. | |||
