Powering Group of Circuit
Doubts and proposals of the procedure reviewing team
(Gianluigi, Rob, Sandrine, Matteo, Boris)
Ref document: LHC-MPP-HCP-071
• PGC.1 Study the electromagnetic coupling between circuits, devoting special attention to the QPS detectors. This group of tests is done at powering subsector level.
• PGC.2 Validation the performance of the DFB and current leads when all the circuits of one DFB are powered as well as the long term behaviour, at sector level, by using an overall current profile representative of a machine operation configuration. It is also a last check of the superconducting splices. – The PGC1 and PGC2 tests should be performed with all the circuits ramping at the
acceleration and ramp rates achieved during the commissioning. These will possibly match the nominal acceleration and ramp rates.
• PGC.3 Validation the squeeze functions of the machine.• PGC.4 Final machine validation by powering all sectors in
unison

• This test is performed in order to verify any electromagnetic coupling among circuits.
• The list of QPS that triggered should be determined and the QPS signals should be verified in order to understand whether a quench occurred.
• Is it necessary to do it taken into account that the following tests should allow to verify that as well.

• The fast power abort of the superconducting dipole will produce a fast power abort of all the circuits in the corresponding powering sub-sector. – Test performed to verify the correct
operation of the GPM? These tests are likely no more necessary because there is already a test at 0/I_min_op current during the PIC Global protection mechanism test during the HW commissioning of each circuit
– Verification of the electromagnetic coupling among the circuits sharing the same DFB?. The list of QPS that triggered should be determined and the QPS signals should be verified in order to understand whether a quench occurred. How many circuits can be coupled?

• To be performed in the matching sections containing cryostats that have several main circuits fed by a DFB. These are those fed from a DFBL (it is considered that they belong to the same cryostat) or by a DFBM that contain more than one main circuit (e.g. D2Q4 or D4Q5 cryostats). However all the circuits of the matching section are included in the test.
• The circuit going through the slow abort has to be specified for each matching section. In case it is a MQM/MQY circuit, the power permit must be removed only in one of the converters leaving the other ON. Why that?
• Do we need such test?• List of parameters to be recorded: The list of

• ABP working on it (S. Fartoukh and M. Giovannozzi) – first draft in within following weeks.
• Once upon a time there was a MTF step/field called MPP OK for each circuit which, once filled as “ok”, determined the start of the powering test of that circuit.
• Those MTF field are still there, but largest part empty. Accessing MTF is heavy if done per circuit!
• This year: MP3_OK sequence requiring an MP3 expert signature and an automatic fill of MTF field.
AOB: MP3 OK for powering
