Overall

- I have installed PLACET code in Manchester afs machine. It worked properly and I have run example file of ilc. Further learning will carry on.

- I have got ABCI code worked on my laptop and Ieyasu pc. I learned to create input file and done with TESLA identical cell structure.

- I drew TTF-style power coupler in MWS and simulated with 9 cells and 4.5 cells. These simulations were done with varying mesh size.

- I have run 9 identical cells and 9 cells structure with ERLP-style coupler again. I found that my simulation was wrong in geometry creation. I have defined coupler materials as vacuum and united with the cavity, but in reality and in Dr. G. Burt simulation the coupler materials was defined as PEC and didn’t unite with the cavity.

- I have installed VM Player for SAGE math code on my laptop, but I have problem downloading SAGE code file. The file size is too big.
