ONCS Component Naming Conventions
From: ONCS Group
Date: April 13, 1998
Devices or components which are addressable by ONCS online software are identified by an ASCII name of up to 32 characters. The name consists of the following conventions for assembling a name from the type of device that is being addressed and the part of the PHENIX detector where the device lives.
Device names are composed of fields that are separated by an ASCII period ".".
Device name fields identify the device type, sub-system, arm, side, one or more sub system specific segments, followed by a unit number where appropriate
A device type identifies an addressable component of the PHENIX detector.
Identifiable fields are included in a device name as they are appropriate to that device. So not every device has, for instance a side field.
Device names are not case sensitive.
The following tables identified the abbreviations that are used to identify a device of the PHENIX detector.
The following ASCII identifiers identify sub systems.

Examples of the use of the naming convention follow for the High Voltage and the DCM components as they would be addressed with this convention:
MVD
Dcm
Dcm’s of the mvd reside in wedges. Each wedge are numbered from 0 – 11 , starting at phi = 0. An MVD DCM would be named:
DCM.MVD.[E,W].[N,S].EN.WEDGE[0-11]
High Voltage
HV.MVDB.H[E,W].EN[N,S].SH[0-1].RO[0-5]
HV.MVDE.EN[N,S].HA[E,W].WE[0-11]
DRIFT CHAMBER
Dcm
Each keystone is associated with an arm and a side. There are 20 keystones per side. There is 1 FEM card per keystone.
On day 1 there will be 1 DCM per keystone (1 DCM per FEM on 1 keystone).
On day N, there will be 2 DCMs per keystone.
The names of the drift chamber DCMs will be
DCM[0-1].DC. [E,W].[N,S].KS[0-19].
High Voltage
HV.DC.[E,W].[N,S].KS[0-3].[0-3]
PbSc
DCM
PbSc consists of 6 sectors.
Each dcm is mapped to one Fem. Each FEM is mapped to one supermodule. There are 18 supermodules per sector. Sectors are located on either arm. So a DCM can be found by the follow name:
DCM.PBSC.A[E].SE[0-6].SM[0-17]
High Voltage
HV.PBSC.[E,W].SE[0-3].SR[0-2].SC[0-5].[0-2]
PbGl
PbGl consists of 2 sectors.
Each dcm is mapped to one Fem. Each FEM is mapped to one supermodule. There are 32 supermodules per sector. Sectors are located on either arm. So a DCM can be found by the follow name:
DCM.PBGL.A[E].SE[0-2].SM[0-31]
High Voltage
HV.PBGL.[E,W].SE[0-1].SR[0-3].SC[0-7].RO[0-11].CO[0-11]
TEC
DCM
For each arm TEC consists of 4 sectors. Each sector consists of 6 planes numbered 1 to 6.
Planes 1 to 5 each have 7 FEM modules..
FEM to DCM Mapping
One day 1 there are 4 FEM’s per DCM.
On day N, there is 1 FEM per DCM.
A DCM can be found with the following name:
DCM[0-1].TEC.[E,W].[N,S].SE[0-3].PL[0-5]
High Voltage
HV.TEC.[E,W].[N,S].SE[0-3].PL[0-5].[0-3]
PC
DCM
The PC has 3 planes for each arm. Planes are divided into half sectors. Each half sector has a single FEM.
FEM to DCM Mapping
On day 1 there are 2 FEM’s per DCM. Day 1 has 2(fem) X 8 (half sectors) X 3 planes X 2 (arms) = 96 FEMs (48 DCMs).
On day N there is 1 FEM per DCM
A DCM can be found with the following name:
DCM[0-1].PC.[E,W].[N,S].SE[0-3].PL[0-3].HS[0-7]
High Voltage
PC 2,3
HV.PC.[E,W].[N,S].SE[0-3].[0-3]
PC 1
HV.PC.[E,W].[N,S].SE[0-7].[0-3]
TOF
TOF has detector elements identified by the arm, side, sector, panel, strip , slat and end.
Each segment has the following range:
ARM[0].SIDE[0-1].SECTOR[0-1].PANEL[0-3].STRIP[0-31].SLAT[0-2].END[0-1].
There are 10 panels total. Two in sector 0 and 8 in sector 1. The sectors are split between the north and south side. So there are 4 panels in each side of each sector.
Each TOF panel consists of 96 slats (scintillators) and each slat has two PMT’s , one on each ends.
FEM to DCM Mapping
On day 1 there are 16 FEM per DCM. One 64 FEMs per DCB.
The mapping of FEMs to PMTs needs to be verified by H. Sako.
So a DCM has the following identification:
DCM.TOF. [N,S].[E,W].SE[0-1].PA[0-3].ST[0-31].SL[0-2].EN[0-1]
High Voltage
HV.TOF.[E,W].[N,S].SE[0-1].PA[0-3].ST[0-31].SL[0-2].[0-1]
RICH
DCM
Rich identifies detector elements by arm, side supermodule row and pmt.
Each segment has the following range of elements:
A DCM would be identified by the following name:
DCM[x].RICH.[N,S],[E,W],SU[0-39].RO[0-1]
High Voltage
HV.RICH.[E,W].[N,S].SM[0-39].RO[0-1].[0-15]
MUID
DCM
MuId maps a FEM to a single DCM. There is one FEM for each of the horizontal and vertical tubes for each arm.
A DCM would be identified by the following name:
DCM.MUID.[N,S].T[H,V]
High Voltage
HV.MUID.[N,S].GP[0-4].PA[0-7].[0-7].T[H,V]
MUTR

A MUID detector element is mapped to a detector arm, a station and an octant.
MUTR FEM to DCM mapping needs to be verified.
