# Notebooks for Circuit Analysis of HWC Tests and Events during Operation
Although, as the project name indicates, our primary goal is the development of signal monitoring applications, we realized that the analysis modules developed so far can be pieced together into HWC test and operation analysis notebooks.

Even though, we develop the analyses system by system, they were developed in a general way to account for all circuits in which the system was present. Thus, by taking a perpendicular view of the analysis table, a circuit analysis for this stance was possible.

In particular, thotebooks are suited for HWC tests: 
- can be adjusted on-the-fly for new requirements while performing a test; 
- can immediately generate a report for storage and distribution among a team of domain experts; 
- provide a sequential way of testing each system in a given order.

## 3. 600A Circuits
The 600-A circuits come in one of two main variants: 
- circuits with 
- and without EE. 
59

Michal Maciejewski's avatar
Michal Maciejewski committed
60
Each variant may or may not be equipped with a DC contactor ensuring the effectiveness of the crowbar in case of a PC short circuit. Moreover, the magnets of several circuits are equipped with parallel resistors, in order to decouple the current decay in a quenching magnet from that in the rest of the circuit. Figure 1 shows a generic circuit diagram, equipped with EE and parallel resistor, as well as lead resistances and a quench resistance.

1. Go to http://nxcals-docs.web.cern.ch/current/user-guide/data-access/nxcals-access-request/ for most updated procedure
2. Send an e-mail to mailto:acc-logging-support@cern.ch with the following pieces of information:
 - your NICE username
 - system: WinCCOA, CMW
 - NXCALS environment: PRO
 
Optionally one can mention that the NXCALS database will be accessed through SWAN.
Once the access is granted, you can use NXCALS with SWAN.

## 2. Logging to SWAN
The following steps should be followed in order to log-in to SWAN
1. Go to http://swan.cern.ch
2. Login with your NICE account
  - SWAN is tightly integrated with CERNBox service (in fact, files created in SWAN are accessible in CERNBox). In case you have not used CERNBox, the following error message will be displayed in- dicating that your CERNBox account has not been activated yet. In order to activate your CERNBox account, please login on the website: http://cernbox.cern.ch. Afterwards, please login to SWAN service again. In case the error persists, please contact the SWAN support (see Section Help and Feedback at the bottom).

## 3. Setting an Environment Script
In order to execute the HWC notebooks, one requires `lhc-sm-api` package and HWC notebooks. To this end, we created a dedicated environment script to prepare the SWAN project space.
The script sets a path to a virtual environment with the necessary packages (for more details, cf. https://lhc-sm-api.web.cern.ch/lhc-sm-api/user_install.html#preinstalled-packages) as well as makes a copy of HWC notebooks to `hwc` notebooks. **Note that in order to ensure compatibility between package and notebook versions, the `hwc` folder is deleted each time the script is executed'.**
Firstly, contact the Signal Monitoring team (mailto:lhc-signal-monitoring@cern.ch) in order to get read access to the EOS folder with pre-installed packages and HWC analysis notebooks.

A notebook is composed by cells.  A cell contains either a markdown text with description or python code toexecute. Cells with markdown text have white background and can contain text, tables, figures, and hyperlinks.Cells with code have gray background and are executed by clicking a run icon in the top bar highlighted in Figure below. Alternatively, one can put a cursor in a cell with code an press a keyboard shortcut Ctrl+Enter.

![SWAN Execute Cell](figures/swan-execute-cell.png)

A state of a cell is indicated by square brackets located on the left to a cell. Execution of a cell is indicatedby a star in the square brackets. Once cell execution is completed the star changes into a number representingthe order of cell execution. A cell can execute for too long due to connection problems, issues with a databasequery, kernel problems. In this case, two actions are recommended:
1.  Select from the top menu: Kernel -> Interrupt and execute the problematic cell again (either a run button (cf. Figure above) or Ctrl+Enter).
2.  In case the first option does not help, select from the top menu Kernel -> Restart & Clear Output.  Thenall cells prior to the problematic one have to be executed again (multiple cell selection is possible byclicking on the left of a cell to select it and afterwards selecting others with pressed Shift button).  After this operation one needs to reconnect to the NXCALS Spark cluster.

# Analysis Notebook for Operation
Quench analysis assumptions:
1. We consider standard analysis scenarios, i.e., all signals can be queried from the respective databases. Depending on what signal is missing, an analysis can raise a warning and continue or an error and abort the analysis.
2. 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.
3. 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).

# Analysis Workflow

An FPA analysis workflow consists of four steps: (i) finding of an FGC Post Mortem timestamp (ii) executing analysis cells on the cluster (iii); (iv) storing output files on EOS; see Figure below.

![FPA Analysis Workflow](figures/fpa-analysis-workflow.png)

The RB FPA Analysis notebook is organized into 11 chapters:
0. Initialise the working environment
Loads external packages as well as lhcsmapi classes required to perform analysis and plot results.
1. Select FGC Post Mortem Entry
After executing this cell, a FGC Post Mortem GUI with default settings is displayed.
![SWAN RB FPA Analysis FGC PM Browser Empty](figures/swan-rb-fpa-analysis-fgc-pm-browser-empty.png)

The GUI consists of 8 widgets described in Table below.

|Widget|Description|
|------|-----------|
|Circuit name|Circuit name|
|Start|Start date and time|
|End|End date and time|
|Analysis|Automatic (each cell executed without user input); Manual (some analysis steps take expert comment)|
|Done by|NICE login of a person executing the analysis|
|Find FGC PM entries|Button triggering a search of FGC PM entries|
|Query progress bar|Displays progress of querying days in between indicated datesFGC PM EntriesList of FGC PM timestamps|

**Please note that in order to execute any of the following cells, there should be at least one entry in the FGC PM Entries list. The list is populated after clicking [Find FGC PM entries button].**

Figure below shows the GUI after clicking button [Find FGC PM entries] with the default settings. Note that the list only contains FGC PM timestamps surrounded by QPS timestamps (1 minute before and 5 minutes after an FGC PM timestamp).

![SWAN RB FPA Analysis FGC PM Browser](figures/swan-rb-fpa-analysis-fgc-pm-browser.png)

2. Query All Signals Prior to Analysis  
In order to avoid delays between analyses, the necessary signals are queried prior to performing the analysis.
3. Timestamps  
Table of timestamps main systems representing the sequence of events for a given analysis.
4. Schematic  
Interactive schematic of the RB circuit composed of: power converter, two energy extraction systems, current leads, magnets, and nQPS crates. Hovering a mouse over a center of a box representing a system provides additional pieces of information. Location of quenched magnets is highlighted. Slider below the schematic enables its scrolling.

5. PIC  
Check of PIC timestamps
6. Power Converter  
Analysis of the main power converter as well as earth currents.  
7. Energy Extraction Analysis of the energy extraction voltage and temperature
8. Quench Protection System Analysis of the quench detection system, quench heaters, diode, voltage feel- ers, and diode leads.
9. Current Leads Analysis of the current leads voltage (resistive and HTS).
10. Plot of Energy Extraction after 3 h from an FPA
11. Final Report  
Saving of the CSV results table and HTML report to EOS folder.
The RQ analysis notebook follows the same structure except for the lack of schematic. Typically, there is only a single main quadrupole magnet quenching and the schematic does not provide more information as compared to the timestamps table in point 3.

### Notebook Output

The notebook creates three output files in the folder //cern.ch/eos/project/l/lhcsm/operation/RB/circuit_name/\*}, e.g., //cern.ch/eos/project/l/lhcsm/operation/RB/RB.A12/\*:
- HTML report file with the snapshot of the entire notebook - [fgc-timestamp]-[analysis-execution-date]-[notebook-name]\_report.html;
- CSV file with MP3 results table with a subset analysis results - [fgc-timestamp]-[analysis-execution-date]-[notebook-name]\_mp3\_results\_table.csv};
- CSV file with full results table - [fgc-timestamp]-[analysis-execution-date]-[notebook-name]\_results_table.csv};

# Analysis Notebook for HWC
## Analysis Workflow

A HWC analysis workflow consists of four steps: (i) finding of start and end time of an HWC test (ii) executing analysis cells on the cluster (iii); (iv) storing output files on EOS; see Figure below.

## Notebook Structure

Each notebook is composed of initial part with a circuit schematic, test current profile, and table summarising test criteria. This part is followed by package import instructions, display and the browser of HWC tests; see Figure below.

The remainder of each notebook depends on the particular test to be performed. At the end of an HWC notebook there are instructions for saving the output files.

## Notebook Output

The notebook creates three output files in the folder 
```
//cern.ch/eos/project/l/lhcsm/hwc/RB/ circuit_name/hwc_test/hwc_campaign/*, 
```
e.g., 
```
//cern.ch/eos/project/l/lhcsm/hwc/ RB/RB.A12/PNO.b2/HWC_2014/*:
```

- HTML report file with the snapshot of the entire notebook - [test-start]-[test-end]\_report.html;

# Help and Feedback
Despite thorough testing, while using LHC-SM quench analysis notebooks two types of issues can occur, related to: 
- analysis (e.g., wrong analysis results, corrupted plots, etc.); 
- SWAN (e.g., package installation problems, connection errors, service unavailability, etc.).

## 1. LHC Signal Monitoring
In order to provide feedback and ask for help regarding the analysis modules, you are cordially invited to contact the LHC Signal Monitoring team (mailto:lhc-signal-monitoring@cern.ch).

## 2. SWAN
There are three ways to contact SWAN support for help related to the service:
- Asking SWAN Community through a dedicated user forum: https://swan-community.web.cern.ch
- Creating a support SNOW ticket: https://cern.service-now.com/service-portal/function.do?name=swan
- Reporting a bug on dedicated JIRA platform: https://its.cern.ch/jira/projects/UCA/issues/UCA-359?filter=allopenissues

All three links are also available in the footer of SWAN website as shown in Fig. 3.1.
