Two types of post-solitons were observed. We found that unlike the ions, which are expelled from the centre of post-soliton, electrons oscillate around the centre of a post-soliton and the resultant poloidal electric vector field behaves like an oscillating electric dipole. The toroidal magnetic field also oscillates along with electrons. On the timescale of ��� −1, where ��� is the ion plasma frequency, protons have evolved into multi-shell structures due to Coulomb explosion in the post-soliton. The polarization of the postsoliton is found to be different from that of the driver laser beam PB - JACoW CP - Geneva, Switzerland SP - 138 EP - 140 KW - ion KW - laser KW - plasma KW - electron KW - proton DA - 2018/02 PY - 2018 SN - 978-3-95450-199-1 DO - 10.18429/JACoW-SAP2017-TUDH3 UR - http://jacow.org/sap2017/papers/tudh3.pdf ER -
