<h1><center>Analysis of a PNO.A9 HWC Test in an IT Circuit</center></h1>
The main quadrupole magnet circuits of the 8 Inner Triplet (IT) systems in the LHC are composed of four single aperture quadrupole magnets in series and have a particular powering configuration, consisting of three nested power converters (PC), see Figure below.
<img src="https://gitlab.cern.ch/LHCData/lhc-sm-hwc/-/raw/master/figures/it/IT.png" width=75%>
Main quadrupole magnet circuit of the Inner Triplet system for IT’s at points 1 and 5 (left) and IT’s at points 2 and 8 (right).
Note that the configuration for the IT’s in points 1 and 5 is different from the configuration in points 2 and 8. An earth detection system is present at the minus of the RTQX2 converter. Detailed information concerning the converters is given in EDMS 1054483. Note that the currents in the quadrupole magnets are given by:
\begin{equation}
I_\text{Q1} = I_\text{RQX} + I_\text{RTQX1} \\
I_\text{Q2} = I_\text{RQX} + I_\text{RTQX2} \\
I_\text{Q3} = I_\text{RQX} \\
\end{equation}
The two magnets Q1 and Q3 are type MQXA and the two combined magnets Q2a and Q2b are type MQXB. Q1 is located towards the interaction point.
Note that the IT’s at points 2 and 8 have a slightly higher nominal operating current than the IT’s at points 1 and 5, see Table 1.
|Circuit|I\_PNO RQX|I\_PNO RTQX2|I\_PNO RTQX1|
|-------|----------|------------|------------|
|RQX.L2, RQX.R2, RQX.L8, RQX.R8|7180 A| 4780 A|550 A|
|RQX.L1, RQX.R1, RQX.L5, RQX.R5|6800 A| 4600 A|550 A|
### PNO.A9: Training and plateau at nominal current
The aim of this test is:
- to reach nominal current with a small margin, required for stable operation, which might require some training quenches,
- to check the correct behaviour of the leads during a plateau,
- to check the splice resistances,
- to check the correct functioning of the PC’s during a current cycle.

# Analysis Assumptions
- We consider standard analysis scenarios, i.e., all signals can be queried. Depending on what signal is missing, an analysis can raise a warning and continue or an error and abort the analysis.
- In case an analyzed signal can't be queried, a particular analysis is skipped. In other words, all signals have to be available in order to perform an analysis.
- It is recommended to execute each cell one after another. However, since the signals are queried prior to an analysis, any order of execution is allowed. In case an analysis cell is aborted, the following ones may not be executed (e.g. I\_MEAS not present).
# Plot Convention
- Scales are labeled with signal name followed by a comma and a unit in the square bracket, e.g., I_MEAS, [A]
- If a reference signal is present, it is represented with a dashed line
- If the main current is present, its axis is on the left. Remaining signals are attached to the axis on the right. The legend of these signals is located on the lower left and upper right, respectively.
- The grid comes from the left axis
- Title contains timestamp, circuit name, signal name allowing for re-access the signal.
- The plots assigned to the left scale got colors: blue (C0) and orange (C1). Plots presented on the right have colors red (C2) and green (C3).
- Each plot has an individual time-synchronization mentioned explicitly in the description.
- If an axis has a single signal, change color of the label to match the signal's color. Otherwise, the label color is black.

<h1><center>Analysis of a PNO.D14 HWC Test in an IT Circuit</center></h1>
The main quadrupole magnet circuits of the 8 Inner Triplet (IT) systems in the LHC are composed of four single aperture quadrupole magnets in series and have a particular powering configuration, consisting of three nested power converters (PC), see Figure below.
<img src="https://gitlab.cern.ch/LHCData/lhc-sm-hwc/-/raw/master/figures/it/IT.png" width=75%>
Main quadrupole magnet circuit of the Inner Triplet system for IT’s at points 1 and 5 (left) and IT’s at points 2 and 8 (right).
Note that the configuration for the IT’s in points 1 and 5 is different from the configuration in points 2 and 8. An earth detection system is present at the minus of the RTQX2 converter. Detailed information concerning the converters is given in EDMS 1054483. Note that the currents in the quadrupole magnets are given by:
\begin{equation}
I_\text{Q1} = I_\text{RQX} + I_\text{RTQX1} \\
I_\text{Q2} = I_\text{RQX} + I_\text{RTQX2} \\
I_\text{Q3} = I_\text{RQX} \\
\end{equation}
The two magnets Q1 and Q3 are type MQXA and the two combined magnets Q2a and Q2b are type MQXB. Q1 is located towards the interaction point.
Note that the IT’s at points 2 and 8 have a slightly higher nominal operating current than the IT’s at points 1 and 5, see Table 1.

### PNO.D14: PC Failure at 50% of I_PNO during an SPA
The aim of this test is to calculate the splice resistances, check the regulation of the current leads, check the margin between U_RES and the QPS threshold for board A and B, and verify the correct functionality of the PC when a powering failure is generated. The currents are equal to 50% of the nominal current in the RQX, RTQX1, and RTQX2 converters, see figures below.

# Analysis Assumptions
- We consider standard analysis scenarios, i.e., all signals can be queried. Depending on what signal is missing, an analysis can raise a warning and continue or an error and abort the analysis.
- In case an analyzed signal can't be queried, a particular analysis is skipped. In other words, all signals have to be available in order to perform an analysis.
- It is recommended to execute each cell one after another. However, since the signals are queried prior to an analysis, any order of execution is allowed. In case an analysis cell is aborted, the following ones may not be executed (e.g. I\_MEAS not present).
# Plot Convention
- Scales are labeled with signal name followed by a comma and a unit in the square bracket, e.g., I_MEAS, [A]
- If a reference signal is present, it is represented with a dashed line
- If the main current is present, its axis is on the left. Remaining signals are attached to the axis on the right. The legend of these signals is located on the lower left and upper right, respectively.
- The grid comes from the left axis
- Title contains timestamp, circuit name, signal name allowing for re-access the signal.
- The plots assigned to the left scale got colors: blue (C0) and orange (C1). Plots presented on the right have colors red (C2) and green (C3).
- Each plot has an individual time-synchronization mentioned explicitly in the description.
- If an axis has a single signal, change color of the label to match the signal's color. Otherwise, the label color is black.

<h1><center>Analysis of a PNO.D16 HWC Test in an IT Circuit</center></h1>
The main quadrupole magnet circuits of the 8 Inner Triplet (IT) systems in the LHC are composed of four single aperture quadrupole magnets in series and have a particular powering configuration, consisting of three nested power converters (PC), see Figure below.
<img src="https://gitlab.cern.ch/LHCData/lhc-sm-hwc/-/raw/master/figures/it/IT.png" width=75%>
Main quadrupole magnet circuit of the Inner Triplet system for IT’s at points 1 and 5 (left) and IT’s at points 2 and 8 (right).
Note that the configuration for the IT’s in points 1 and 5 is different from the configuration in points 2 and 8. An earth detection system is present at the minus of the RTQX2 converter. Detailed information concerning the converters is given in EDMS 1054483. Note that the currents in the quadrupole magnets are given by:
\begin{equation}
I_\text{Q1} = I_\text{RQX} + I_\text{RTQX1} \\
I_\text{Q2} = I_\text{RQX} + I_\text{RTQX2} \\
I_\text{Q3} = I_\text{RQX} \\
\end{equation}
The two magnets Q1 and Q3 are type MQXA and the two combined magnets Q2a and Q2b are type MQXB. Q1 is located towards the interaction point.
Note that the IT’s at points 2 and 8 have a slightly higher nominal operating current than the IT’s at points 1 and 5, see Table 1.

### PNO.D16: PC Failure at 90% of I_PNO
The aim of this test is to calculate the splice resistances, check the regulation of the current leads, and verify the correct functionality of the PC when a powering failure is generated. The currents are equal to 90% of the nominal current in the RQX, RTQX1, and RTQX2 converters, see figures below.
