    991. //Introduction, notes and actions//: KL/All
    1010 * **KL/RB:** Take a look at the Bingham et al paper on laser-driven accelerator for medicine
    … …  
    1414 * See slides.  Discussion of possible causes of instablility observed.  Agreed that helping get the best from the paper was of interest to the capture group.  The capture people were "up-for" helping with the understanding of the instablilities.

    16 3. //Updates on the particle generation//: **HT**
     163. //[raw-attachment:180620_HTL.pdf Updates on the particle generation (2 micron thin foil)]//: **HT**
    1717 * Improved simulations presented.  Issue of banding discussed.
    1818 * Discussion of boundary effects and types of boundary that had been assumed.
    … …

    21214. //Updates on VSim simulations//: **TSD**
     22 * [raw-attachment:LhARA_Capture_18Jun20_TSD.ppsx Second simulation of the lens]
    2223 * See slides.  N_e increased, other parameters adjusted.  Plasma oscillations still observed, but, the effective length of the plasma has been stablisised.
    2324 * Suggest to increase field to 0.1T.= in an attempt to stabilise the lateral oscillations.  Noted that this will cause length of plasma to reduce.
