Linac Locking - A System Level Overview
IOC Description
The IOC provides the controls and a monitoring capability for a low drift and low phase noise continuous-wave optical link system. The latter is used for the transmission of a 3GHz RF reference signal over long distance. The system consists of a Transmitter (Tx) and a Receiver (Rx) that are connected with two single mode fibers (SMF) (optical links). To achieve low phase noise performance, the RF signal is propagated through the unidirectional optical link. The low noise link is additionally stabilized against phase drifts with the bidirectional phase-compensated optical link (low drift link). An ethernet connection between the units is also needed for data exchange and control purposes. We will refer to this system as an RF-over-Fiber (RFoF) system.
Equipment State Machine
The control system for RFoF consists of a state machine responsible for the initialization, tuning and reliable operation of the system. The state machine consists of 6 states and its functional view is provided below.
...
Also, the Tx unit receives data from Rx via the ethernet connection at all time. In the case of a broken ethernet connection, the system goes from LOCKED to UNLOCKED. This may eventually cause the system to go to SHUTDOWN, unless the connection is reestablished within 10 minutes.
IOC Deployment
In this section, we address IOC deployment details such as the App hosting the RFoF Telnet IOC, IOC name and the assigned CPUs in both Dev and Production.

IOC Bootup
In this section, a detailed description of the IOC bootup process is laid out.
Generic variable definition
First, define the usual environment variables in the startup script.
| Code Block | ||
|---|---|---|
| ||
# ===========================================
# ENVIRONMENT VARIABLES
# ===========================================
epicsEnvSet("IOC", "sioc-sys0-ms11" )
epicsEnvSet("DEVICE", "MSLK" )
epicsEnvSet("LOCA", "SYS0" )
epicsEnvSet("UNIT", "MS11" )
epicsEnvSet("IOC_NAME", "SIOC:$(LOCA):$(UNIT)" )
epicsEnvSet("IOC_PV", "$(DEVICE):$(LOCA):$(UNIT)" )
epicsEnvSet("PREFIX", "${IOC_PV}" )
epicsEnvSet("INDEX", "0" )
epicsEnvSet("ENGINEER", "Michael Skoufis" )
epicsEnvSet("TXIP", "172.27.136.38" )
epicsEnvSet("RXIP", "172.27.136.39" )
epicsEnvSet("STREAM_PROTOCOL_PATH", "$(TOP)/rfofApp/srcProtocol")
|
Common setup
Load dbd and IOC health/monitoring records. Also, set up autosave and load the LCLS access configuration file. Finally, copy the archive file in $IOC_DATA to enable record archiving.
| Code Block | ||
|---|---|---|
| ||
## Load dbd
dbLoadDatabase("dbd/masterSource.dbd", 0, 0)
masterSource_registerRecordDeviceDriver(pdbbase)
## Environment variables
epicsEnvSet("ENGINEER", "MICHAEL SKOUFIS")
#epicsEnvSet("STREAM_PROTOCOL_PATH", "${TOP}/db")
## Tag log messages with IOC name
epicsEnvSet("EPICS_IOC_LOG_CLIENT_INET", "${IOC}")
## Load records
# **** Load iocAdmin databases to support IOC Health and monitoring ****
dbLoadRecords("db/iocAdminSoft.db", "IOC=${IOC_NAME}")
dbLoadRecords("db/iocAdminScanMon.db", "IOC=${IOC_NAME}")
dbLoadRecords("db/iocRelease.db", "IOC=${IOC_NAME}")
## Autosave initialization
#< $(TOP)/iocBoot/common/autosave_init.cmd
## Channel Access Security:
# This is required if you use caPutLog.
# Set access security file
# Load common LCLS Access Configuration File
< ${ACF_INIT}
## Update archive pv list in ${IOC_DATA}
system("cp $(TOP)/archive/${IOC}.archive ${IOC_DATA}/${IOC}/archive/") |
Autosave initialization
Tell the IOC where to find the list of record names that and where they will be autosaved. Also, restore previously autosaved values.
| Code Block | ||
|---|---|---|
| ||
# =====================================================================
# Load database for autosave status
# =====================================================================

# ============================================================
# If all PVs don't connect continue anyway
# ============================================================

# ============================================================
# created save/restore backup files with date string
# useful for recovery.
# ============================================================

# ============================================================
# Where to find the list of PVs to save
# ============================================================
set_requestfile_path("${IOC_DATA}/${IOC}/autosave-req")
# ============================================================
# Where to write the save files that will be used to restore
# ============================================================
set_savefile_path("${IOC_DATA}/${IOC}/autosave")
# ============================================================
# Prefix that is use to update save/restore status database
# records
# ============================================================
save_restoreSet_status_prefix("${IOC_NAME}:")
## Restore datasets

set_pass1_restoreFile("info_positions.sav")
set_pass0_restoreFile("info_settings.sav")
set_pass1_restoreFile("info_settings.sav")

...
Besides the auto-generated record names for autosave, copy the manually generated list of records to be autosaved and restore their previously autosaved values.
| Code Block | ||
|---|---|---|
| ||
# Copy over the manual settings request file
system("cp $(TOP)/autosave/${IOC}.req ${IOC_DATA}/${IOC}/autosave-req/")
# Load manual settings from autosave
set_pass0_restoreFile("${IOC}.sav")
set_pass1_restoreFile("${IOC}.sav") |
Database loading

| Code Block | ||
|---|---|---|
| ||
# ===========================================

EPICS Records
A complete list of the RFoF Telnet IOC Process Variables (PVs) can be found in the page linked below, along with revision dates based on feedback received from the naming team.
Linac Locking - RFoF Telnet IOC (PVs [sioc-sys0-ms11) PVs]
New Displays
Currently, there is no RFoF test stand in Dev and hence only the Production displays are availablein Dev and hence only the Production displays are available.
To launch the linac locking dashboard GUI in Production, log onto the appropriate host (Production ==> lcls-srv01) and then run the command mslk_dashboard:
|
Upon running the command successfully, the following display is invoked. Choose RF over Fiber Expert to monitor the RFoF IOC.
Old Displays
Note that the preferred RFoF display is the one shown above. However, below, we include instructions on how to launch the old display directly if needed.
Production
To access and launch the displays in Production, follow the steps outlined below.
| Code Block | ||
|---|---|---|

[softegr@lcls-srv01 skoufis]$ cd $EPICS_IOCS/sioc-sys0-ms11/iocSpecificRelease/masterSourceApp/srcDisplay/ [softegr@lcls-srv01 skoufis]$ cat masterSourceApp/srcDisplay/README.rfof To run the the RFOF screens, follow these steps from within this directory: 1. $ source /usr/local/lcls/epics/setup/epicsenv-7.0.3.1-1.0.bash 2. $ source /usr/local/lcls/tools/script/ENVS64.bash 3. Invoke the GUI you need, i.e. $ pydm -m "BASE=MSLK:SYS0:MS11" rfof.ui $ pydm -m "BASE=MSLK:SYS0:MS11" Errors.ui $ pydm -m "BASE=MSLK:SYS0:MS11" StateMachine.ui $ pydm -m "BASE=MSLK:SYS0:MS11" TransmitterParameters.ui $ pydm -m "BASE=MSLK:SYS0:MS11" ReceiverParameters.ui |
The RFoF screens are PyDM-based screens and are seen below.
