Agenda:
1)	Looking for best optimization of ASTRA parameters for 100pC charge case.

Results:
1)	Changed the booster gradient from 20 MV/m (ASTRA optimized case for 100pC) to     4 MV/m (9.6 MeV energy after the booster instead of 23.6 MeV) and there is a difference in projected emittance from 0.173 to 0.129 mm mrad. But the gun gradient was instead of 60.58 MV/m  60 MV/m (repeat the simulations for 60MV/m)

Next steps:
What is to be done?	By whom?	Until when?	Done on	
Check the BSA number in the plot for Imain and booster gradient optimization 	Dmitriy Malyutin			
Find out what are the physical reasons for these two minima of parameters. Make a plot for full optimization of parameters (gun phase etc.)	Dmitriy Malyutin, Grygorii Vashchenko			
Not critical but to be checked the gun gradient influence on the optimization parameters (change from 60 MV/m to 60.8 MV/m (same momentum value that we measure usually))	Dmitriy Malyutin
