2. Abstract
SwissFEL has commenced installation and rapidly approaches the first stages of commissioning. Due to the complexity of the machine, communication amongst the groups and services for SwissFEL is imperative. The electronic logbook has been chosen as a tool for the tracking of all SwissFEL relevant activity. The purpose of this talk is to provide an overview of the SwissFEL ELOG s and aid in preparation for commissioning……
Overview of the SwissFEL ELOGs – Definition / Use / Structure
Clarify who writes in which ELOG
Current Experience with RF/LLRF – searching, filtering,…
Discuss what the next stages should be.. Open issues etc.
PSI,

3. A location for recording ALL SwissFEL related activity
Definition
A location for recording ALL SwissFEL related activity
Not the same logbooks (ideally same server)
A vital aid to Commissioning, leading seamlessly to Operations.
Critical for On-call duty personnel.
To identify potential faults
Repeated faults / with possible short term fixes.
Modifications to SwissFEL systems that affect the operation of the machine Must be recorded in the commissioning logbook.
Work on systems unaffecting beam operation to be recorded in Group/service logbooks.
Commissioning Team or Operators to record events only in the `SwissFEL commissioning`logbook

4. ELOG Administration ELOG server - https://elog-gfa.psi.ch/
Secured Location within PSI firewall. Login to server requires VPN when off-site.
Standard PSI username and password
ELOG General Administrator / Technical Support – Andreas Luedeke
SwissFEL Commissioning ELOG Administrator – Didier Voulot
Individual Group ELOGs – Defined by the service or group
Latest Version of ELOG will be maintained.
Attachments
ELOG is NOT a document repository
Do not attach text based documents to ELOG entries.
Slows down the search for all users
Text documents to be stored on Alfresco
Link to the document could be provided instead
Images can be attached.
If there are many images taken, a link to alfresco location is recommended

5. Location – GFA Elog Server - https://elog-gfa.psi.ch/
Current SwissFEL logbooks

6. Whats Changed/Improved
SLS Operations Structure has been adopted (where possible).
Two commissioning Logbooks
SwissFEL Commissioning – (Manual Entries)
Shift Summary – Overview of the Shift achievments – See T.Schietinger
Measurement Summary - Overview of the Measurement Results – See T.Schietinger
Procedures or Workarounds – Temporary changes in procedures to continue operation
Problems – Fault Tracker – Faults/issues to groups systems to be recorded here. – Discussed Next
Info – General Information not covered with other options
Überbrucküng – Overriding of alarm handler recorded here
Pre-beam Checks – Checklists for routine start-up – See D.Voulot
SwissFEL Commissioning Data – (Automated scripts) – See T.Schietinger
Section (or Service) Logbooks
RF – coordinated with LLRF improved structure - Discussed Later
LLRF – coordinated with RF improved structure
Vacuum – Standard layout covering all machines
Laser – Very Basic Layout
Controls – Utilised but not standardised to SwissFEL
Diagnostics– Still mostly on a seperate ELOG server.
Standardised naming convention:
To allow filtering and easier searching
No ambiguity
PSI,

7. Recording Problems/Faults
Any Fault / Observation / Problem that effects the operation of the machine must be recorded on the commissioning ELOG.
The type of fault may not be known exactly, however, the first system that prohibits operation should be highlighted under the System Tab.
Often the final problem may be due to a subsystem or service, however the expert group identified should take the responsibility to ensure the problem is transfered to the required group/service.
The status of the fault will be tracked such that any outstanding issues can be monitored.
The commissioning Team or Operators identifying the fault will record the issue. It is NOT necessary to record the activity in the Group/service specific ELOG.
Once a Problem is recorded, the group identified will recieve an (to pre-identified members) that will assess the problem.

10. Commisioning Logbook Entry - Organisation
Predefined names to avoid miss-spelling or ways of displaying the name..e.g. Jan Chrin, J.Chrin, CJ84, Chrin, Jon Chin…
Depending on the Category chosen, the remaining categories and entry choices are filtered.
On some selectable options a predefined table is generated.

11. SwissFEL RF Logbook – Already Operational
Many groups already have an ELOG, but not excessively used.
Vacuum, RF and LLRF have centralised their ELOGs and already in an operational state

12. Data Entry – RF ELOG
A comprehensive structure reduces the need for the detailed explanations.
Fast and Simple to complete
Enables filtering and speeds searches

13. Filtering
Filtering allows a fast method for collecting information on a specific topic.
The selected filters can also be saved as Browser Favourites
A well defined structure, provides a much improved filtering

14. All Log book search Only possible with a standardised categorisation
Allows the possibility of searching all log books at a specific location
Helpful for fault finding

15. All Log book search 2
By filtering the data for location, time, or system, it is possible to identify what work has been carried out. This may identify any activity that may have had an impact on the machine behviour or fault.

16. Status – Next Steps Commissioning ELOG progressing well…
Still time to Plan/Prepare the logbook structure (before commissioning)
A good structure encourages more people to make entries.
Consistency amongst entries
Easier for shift worker / commissioning team / operator to find a solution to common faults.
Reduces the number of call-outs / machine down-time
Quick to track commissioning progress/outstanding issues
Next Steps
Each group/section should define what information is relevant for commissioning/operations.
Commissioning/Operations Team to define what information MUST be recorded.
A designated Spokesperson for each group/section to ensure the logbooks are structured/relevant to the groups needs.
The logbooks are not optimal, thereofore Everybody should have a look at the SwissFEL logbooks and identify any improvements/changes/suggestions.

18. Advanced options (Future Talk)
I’ve only concentrated on the very basic ELOG configuration Andreas Luedeke could advise in the future on Automated Shift entries Fault Tracking Form generation Checklist options. Plus many more time saving applications ;-)

19. Systems Overview
We have many systems for recording Machine information, the functions are clearly defined as:
Alfresco
documents repository
Specifications
Data sheets, reports, photos, etc.
Wiki
General Information
Overviews of Systems
Procedures
Inventory database
Information relevant to each device
item location
Item history
ELOG
NOT a repository for documents
Recording day to day operation of the machine
Recording test results
Changes to systems
