1. ELENA Layout Naming Convention F. Butin / ELENA collaboration

2. Document ready to be approved Document currently under « engineering check » in EDMS (https://edms.cern.ch/document/1228775/1/TAB3 )https://edms.cern.ch/document/1228775/1/TAB3 F. Butin / ELENA collaboration

3. Definition Conventions to be used when attributing names to components of the ELENA layout, i.e. the functional positions (also called slots) of ELENA. Not to be confused with the part identifier of the physical equipment installed in the slot. Based on PS complex in general, LINAC4 in particular F. Butin / ELENA collaboration

4. What is included Machine layout: functional positions of all elements on or along the beam path of ELENA Layout of electrical circuits: circuits with their main constituents, eg power converter(s) and the load Layout of racks and electronics: racks and chassis in the vicinity of ELENA F. Butin / ELENA collaboration

5. Machine layout (1) Syntax: ELENA Zone, Functional Equipment Code, Position Number F. Butin / ELENA collaboration

6. LNE 50 - 99 LNR 01 -06 LNILNS LNE 00 -49

7. Machine layout: equipment code Functional equipment code: official code in the list of equipment of PS- Complex Some equipment codes must be checked (e - cooler, electrostatic deflectors…) F. Butin / ELENA collaboration

8. Machine layout: Position number Positioning of the layout component within a specific ELENA Zone. First 2 digits : sub-zone within a specific zone Last 2 digits :incremental positioning within the sub-zone, no reference to a metric position. F. Butin / ELENA collaboration

9. Subzones numbering ELENA Zone Naming Zone Delimiting elements Zone range (4 digits) LNR ELENA ringHexagonal ring0100-0699 LNE Transfer line towards experiments TBD 0000-4999 for existing exeriments side 5000 – 9999 for GBar experiments side LNI Injection line Ejection septum in AD –> Injection Septum on LNR 0000 – 0099 LNS H+/- source H+/- source – > Injection kicker 0000 – 0099 F.

10. Subzones numbering F. Butin / ELENA collaboration LNE 50 LNR 01 -06 LNILNS LNE 00 LNE 01 LNE 02 LNE 03 LNE 04 LNE 05 LNE 06 LNE 51

11. Connected sequence of electrical circuit elements, connecting the load (i.e. magnet, magnet string, RF- cavity, kicker,...) to one or several power converters Syntax: ELENA Zone, Circuit Type, Circuit Location Electrical circuits layout F. Butin / ELENA collaboration

12. Electrical circuit type Functional Equipment code of the load Function RBHMBH, BHZHorizontal trajectory bending RBVMBVVertical trajectory bending RQMQD and MQF in seriesFocusing, quadrupolar RQDMQDDefocusing, quadrupolar RQFMQFFocusing, quadrupolar RCHMCHHorizontal trajectory correction RCVMCVVertical trajectory correction RLFMLFFocusing, solenoidal Electron cooler converter Electrostatic elements Other, needed for ELENA F. Butin / ELENA collaboration

13. Electrical circuit location Electrical circuit location defined by the four digits of the location of the first element of the load within the circuit. F. Butin / ELENA collaboration

14. Power converters naming Syntax: Equipment Code, Location, powered Electrical Circuit F. Butin / ELENA collaboration

15. Power converters equipment code Official 5-character equipment code representing the power converter type, as declared in the unique list (following the LHC QAP), with : ‘R’ for power converter equipment ‘P’ for power converters F. Butin / ELENA collaboration

16. Power converters location Location shows the building where the power converter is located (AD hall, bdg 193)… Electrical circuit naming is same as before F. Butin / ELENA collaboration

17. Racks layout naming Syntax: Equipment code, sequence number, location Location is the number of the building, followed by a letter (H= AD Hall, C=AD control room, S=service room) F. Butin / ELENA collaboration

18. Control electronics naming Syntax: Equipment code, location, function The location is the one of corresponding rack The function is optional F. Butin / ELENA collaboration
