this decision with the Crew Chief and communicated with the PDL Baltzell in this regard. As a result, today's Swing shift and tomorrow's Owl and Day shifts are canceled; however, tomorrow's Swing shifters are on standby. I will communicate this info directly
to the corresponding shift takers. Given the counting house will be unattended, the beamline expert Paysuk was contacted to ramp down the Torus and Solenoid fields.<u></u><u></u></span></p>
