-Took over RC duty from Markus at Friday night. Continuing physics production data taking for SIDIS experiment  (kinematics point 3 and 4). Plan for weekend is finished taking data for that kinematics point.

-Swing April 20 shift .     70.7% available beam used ; 10% beam not used due SHMS polarity and angle changing; 19.3% beam was not available

-Owl     April 21 shift.      58%  available beam used;    25% beam not used due mostly SHMS Q1 issue https://logbooks.jlab.org/entry/3564316; 17% beam was not available
-Day     April 21 shift.      80.9% available beam used; 19.1% beam was not available ; Mark Jones updated SHMS charge counter https://logbooks.jlab.org/entry/3564435 
-Swing  April 21 shift.     70.2% available beam used;  13.5% beam not used due SHMS polarity and angle changing; 16.3% beam was not available

-Owl      April 22 shift.     88.75% available beam used; 7.2% beam not used due target changing; 4.05% beam was not available

-So far for this weekend data taking is very smooth and robust so hopefully it will stay like this till Monday day when MCC planned to perform high current beam studies.
-Also we still have gaps in shift schedule so please sign up for shifts and your help will be greatly appreciated.
