DiscussionsDiscussions

� The source of inconsistency between GLA and Lanc models is theway of the First Charge Clocking. Michal will send details of theclocking technique to Dima next week for comparison.

� As was requested last meeting Dima is simulating 130K and 120Kfor 50MHz 0.17eV ± Unfortunately 120K did not converge and I do

not think it could happen. 130K is in progress.� Dima is running simulation for 50MHz 0.44eV with sinusoidal first

charge clocking to estimate computational time required for realclocking of the CPCCD. If it takes less than 120h (max allowed timein ScotGrid cluster) then I will run at least 0.1%, 0.4% and 0.6%.Expecting that 1.0% (= 10uS between charges) would take rest of my life to finish.

� To Lakhdar: could you run simulations for 25MHz 0.44eV 0.4% and0.6% Occupancy. Another case to understand what is wrong withGLA 50MHz clocking model.
