We are ready for beam:

--> LH2 target is ready; TO's are watching it

--> target is now in home and so is the radiator (radiator is out of beam)

--> SHMS and HMS magnets are energized for the first kinematic setting in the J/psi experiment: https://logbooks.jlab.org/entry/3649006 , https://logbooks.jlab.org/entry/3649044

--> SHMS and HMS angles have been set: https://logbooks.jlab.org/entry/3648971 , https://logbooks.jlab.org/entry/3648968

--> The DAQ has been switched by Sylvester to COIN mode and we took a cosmic run after, it looks good; we are currently taking a run triggering on cosmics and 10 Hz from pulser

--> monitoring histograms for detectors look O.K.

--> the HMS shutter issue has been addressed; shutter is now open in preparation for beam (huts doors are closed)

A plan for the ion chambers calibrations is in place (thanks to Daniel Moser for his diligence on this): https://logbooks.jlab.org/entry/3648965 , https://logbooks.jlab.org/entry/3648987

 MCC just took us to power permit. 

They still need the "beam authorization" for C (according to the crew chief work in building 95 has been completed: https://logbooks.jlab.org/entry/3648962) 

They are now setting up Hall B (Hall D took an access for now, however: https://logbooks.jlab.org/entry/3649036).
