Yellow ring is cryostable. The month of May will be used to optimize the performance of the accelerators in preparation for the resumption of research using colliding beams of gold ions.
Refrigerator clean up is complete.
Cooling down refrigerator to operating temperature. The graph below indicates an unusual pulsing event at the exact time of the RHIC sweeps. The frequency bandwidth of the filter of this signal is 2.7 to 3.2 hertz. Solar activity is at a minimum including x-ray emissions and magnetometer indications on a global scale are low. This may indicate the startup of the RHIC operation using gold ions.
