Since restoration of the user machine time in 2013, the approved beam time have been regularly implemented as scheduled. Currently, the 1.3 GeV Booster STorage (BST) ring has been well utilized to generate the high energy gamma-rays as before the disaster. The high energy gamma-rays were produced via Bremsstrahlung by inserting an internal target wire to the beam orbit after the beam acceleration. Since the user machine time was recovered, there were some improvements so far, i.e. realignment of synchrotron magnets, orbit correction in energy ramping process by updating the control of power supplies for steering magnets etc., which brought an increase of the beam current in the maximum energy. Present operational status and recent progress of beam performance in the BST ring are reported.
