1. INTRODUCTION

The main quadrupole circuit of the Inner Triplet system has a particular powering

configuration. It is composed of four magnets in series (two MQXA and two MQXB) and three

nested power converters.

RQX

RTQX2

RTQX1 FWDFWT

Q1 Q2a Q2b Q3

Main quadrupole circuit of the Inner Triplet system in sector 56

This Hardware Commissioning Procedure describes the test sequence, test parameters

and data analysis for the powering test of the LHC inner triplet magnets. The particular

electrical configuration of these magnets (nested power converters) makes this powering

procedure more complex than those for the other LHC superconducting circuits.

The powering procedure should include all the different combinations of the power converters

to assure proper powering for the magnets.

The powering sequence for commissioning of the inner triplet is graphically represented in

chapter 3. As can be seen, the three converters are brought to different current levels in the

following order:

All converters disconnected from the magnets

PIC1 for the three converters in simulation mode- 3 heater discharges into dummy

loads

QPS Individual System Tests

PCC part 1 with RQX and RTQX2

PIC2 for RQX, RTQX1 and RTQX2 (I_MIN_OP) – 1 heater discharge

RQX alone: PLI2 (I_INTERM_1) and PLI3 (I_INTERM_2)

RQX and RTQX2 together: PLI2 (I_INTERM_1), PLI3 (I_INTERM_2) – 1 heater

discharge

RQX and RTQX2 together: PNO (I_PNO)

PCC part 2: with all power converters (RQX, RTQX1 and RTQX2)

RQX, RTQX1 and RTQX2 together: PNO (I_PNO)

This procedure assumes that all previous commissioning steps were successfully

completed and that the circuits have been approved for powering. In addition, the basic

cryogenic conditions, summarised by the CRYO_MAINTAIN and CRYO_START interlock signals,

must be kept stable.

In order to avoid unnecessary quench heater discharge, the FGC of the power

converters has been modified such that the discharge request signal is only issued when the

power converter fault (i.e. water fault) occurs above 3 kA.

The ramp rate and acceleration for all three power converters is always the same and it

is specified in appendix 1.

The entire test consists of 2 phases:

2 converters configuration (RQX and RTQX2) includes

PCL Current leads verification

PCC Power converter configuration

PIC2 Powering interlock controller check with current in the magnets

PLI2 Powering to first intermediate current

PLI3 Powering to second intermediate current

PNO Powering to nominal current

3 converters configuration (RQX, RTQX2 and RTQX1) includes

3.2 PCC PART 1: POWER CONVERTER CONFIGURATION

The aim of this test is to calibrate the converters in the 2-converters configuration.

The PCC tests will be realized by the sequencer from the CCC.

The conditions to start this PCC part are:

1. ElQA has validated the circuit for powering.

2. The circuit has been released for powering by MP3 and the owner of the

different equipments of the circuit.

3. The FGC and the DCCT have been calibrated by PC

Before starting the PCC tests by the sequencer, the power converters have to be

started manually and locally (in the tunnel) by the PC experts to verify that the power

converters are operational. During this check the maximum current in the RQX power

converter is I_RQX_PCC (300A) and I_RTQX2_PCC (250A) in the RTQX2.



of 50

During this manual part the Earth Fault detection system has to be verified, by

creating an earth fault at each output polarity of the power converters and verifying

that the faults are detected by the earth fault detection system of the power converter

RTQX2.

The PCC tests will be realized in two parts and four steps.

During Part1 the power converter RTQX1 is not connected to the magnets.

converters (RQX and RTQX2), but during this part the RTQX2 current will be

constant at I_RTQX2_MIN_OP.

- PCC.T3 (part 1, step 3): The four magnets will be powered by both power

converters RTQX2 and RQX

3.2.1 PCC.T1

IMPORTANT: Before starting the power converters RQX and RTQX2, the

configuration of their FGCs has to be loaded and checked.

Before starting the PCC part 2 tests by the sequencer, the power converters have to

be started manually and locally (in the tunnel) by the PC experts to verify that the

power converters are operational. During this check the maximum current in RQX is

I_RQX_PCC (300A), in RTQX2 is I_RTQX2_PCC (250A) and in RTQX1 is I_RTQX1_PCC

(50A).

During this manual part the Earth Fault detection system has to be verified.

Create earth faults at each output polarities of the power converters and verify that

the faults are detected by the earth fault detection system of the power converter

RTQX2.
