The circuit is powered up to I_PNO + a current margin (I_DELTA). I_PNO is considered as the maximum current which can be used for the operation after the commissioning. During the HWC a current margin will be added for this test. Depending on the I_PNO level, training quenches of the dipole magnets may occur. Even if the test is considered as failed, each system (PC, QPS, magnet...) must be analysed before launching another test run.
After each test resulting in a quench, the MP3 will decide on continuation of the tests, not only taking into account the objective to be reached, but also speed of the training, and the currents reached in the other sectors.
If the I_PNO+I_DELTA current level is reached, an EE is provoked from the plateau.
During this test, the performance of each equipment must be checked
