– Monitoring

– Controls

• Configuration database

• Schedule


EPICS Client / Server Overview


EPICS Server / Client Organisation

• Wide variety of EPICS server applications permitted– Typically connect to physical hardware

• Impossible to enforce common interface/processor/OS specifications

– Each server is maintained by ‘owner’ of respective control system

• Strict central administration unnecessary – ‘end user’ only concerned with availability of PVs on network

• EPICS clients also varied, but must be uniformly accessible– Users should not have difficulty finding/launching clients

– Applications should be consistently organised/updated

– MICE Online Group (MOG) responsibility


EPICS Client Organisation

• All client-side applications run on miceecserv

– Central installation repository greatly simplifies configuration/maintenance/backup

– MOG collates individual applications, applies updates when available from control system ‘owners’

EPICS Client Organisation

• Client control/monitoring GUIs viewed directly on miceecserv, or one of 2 ‘Operator Interface’ PCs

– OPI PCs act as ‘dumb terminals’, running displays from miceecserv via SSH

Unification of Control Systems

• At user level: Simple ‘wrapper’ GUI provides menu for launching individual client applications

• At system level: Employ 2 standard EPICS tools (running as background services on miceecserv)

– Alarm Handler

• Monitors all servers & warns operators of abnormal/dangerous conditions

– Channel Archiver

• Automatically records PV parameters to disk & provides several visualisation options

• See PH’s talk

Remote Monitoring: General Principles

• Remote users should have simple, easily accessible interface for routine monitoring

• ‘Expert’ remote users should have access to monitoring displays which match those in MLCR

• No machine on Controls Network should be directly accessible over the internet

• System load generated by remote monitoring should have minimal impact on control & monitoring services

Remote Monitoring: Direct PV Access

• Could recreate normal client displays using web interface, but would involve impractical development overheads

– Provide direct read only access to PVs so actual client GUIs may be run remotely

Remote Monitoring: Direct PV Access

• CA Gateway makes PVs available across subnets (with full access control), while minimising load on underlying servers

• To simplify end-user support, virtual machine disk image containing EPICS + all client applications will be made available

Remote Control

• Where possible, operations affecting the state of any MICE system should only be performed within MLCR

– Remote users accessing controls can lead to unknown/unexpected running conditions – should be discouraged

• If necessary, off-site experts will be permitted to run control client applications on miceecserv, via SSH through RAL Gateway

– Each expert will have an account on miceecserv which only contains client applications for their designated system


Configuration Database

• Necessary to integrate control systems with central MICE configuration database

1) Read set point values from database

2) Upload PV values to EPICS servers

3) Modify PVs with client GUIs

4) Download PV values from EPICS servers

5) Write new set point values to database

• For (2) & (4) propose use of standard EPICS Backup & Restore Tool (BURT)

– Backup/restore PV values to/from snapshot files


Configuration Database

• BURT snapshot files may be written in ‘Self-Describing Data Sets’ (SDDS) format

• For (1) & (5), propose development of application to write/read database values to/from SDDS files

– C API for generating SDDS snapshots provided with BURT

– C/C++ APIs for database (PostgreSQL) available

• NB: Configuration database interface still in very NB: Configuration database interface still in very early planning stages – details to be early planning stages – details to be discussed/decideddiscussed/decided

– Have not rejected possibility of developing custom backup/restore client which accesses database directly

Tracker: AFEIIts

• AFEIIt configuration, control & monitoring software complete

• Finalisation of DATE integration details required

– Need DATE-side client to enable/disable triggers (i.e. run control)


Alan Bross (FNAL) James Leaver (IC); Jean-Sebastien Graulich (UNIGE) Now; June 2009


Tracker: AFEIIt Infrastructure

• ‘Infrastructure’ corresponds to miscellaneous auxiliary hardware associated with AFEIIts– Somewhat ill-defined, since most hardware (AFEIIt cryo systems &

safety interlocks) integrated with Spectrometer Solenoid controls

• Currently require C&M for AFEIIt power supplies– 4 Wiener PSUs (1 per cryo)

– CAN Bus or RS232 communication interface

• Intend to use RS232 for simplicity

– No progress yet – expect manpower to be available for completion in August

• Additional C&M requirements may develop (to be discussed)


Alan Bross (FNAL) James Leaver (IC) Aug 2009; TBD


Hydrogen Absorbers: Focus Coils

• Absorber Focus Coils expected to require C&M systems very similar to Pion Decay Solenoid & Spectrometer Solenoids

• Would be most efficient for DL to take over project (wealth of relevant expertise)

– Unfortunately prevented by MICE funding constraints

– Task assigned to MOG


Wing Lau (OU) Pierrick Hanlet (IIT); TBD May 2010; TBD



• If possible, will attempt to use DL’s existing magnet designs as template

– DL C&M systems have vxWorks IOCs

• For MICE to develop vxWorks software, expensive (~£15.2K) license required

• Investigate replacement with RTEMS controllers (‘similar’ real-time OS, free to develop)

– DL system include custom in-house hardware

• Not available for general MICE usage – will check alternatives

• However, will consider possibility of entirely new design (perhaps with Linux PC-based IOCs)





• Work on Focus Coil C&M system has not yet commenced

– Need to confirm availability of PH

– Assistance from FNAL Controls Group would be highly beneficial – need to discuss

• Expect to start project in September 2009




RF Cavities: Coupling Coils

• Cavity Coupling Coil C&M situation identical to Focus Coils

– Similar requirements to other MICE magnets

– MOG responsibility (need to confirm PH’s availability)

– Project should run in parallel with Focus Coil C&M system


Derun Li; Steve Virostek (LBNL) Pierrick Hanlet (IIT); TBD Sep 2010; TBD


DATE Status

• Need mechanism for reporting current DAQ state via EPICS

• Simple (‘dumb’) data server hosts DATE status PV

• Client application reads DATE status from DIIM server, forwards value to EPICS server

• Server & display client complete; DATE-side client to be implemented


Jean-Sebastien Graulich (UNIGE) James Leaver (IC); Jean-Sebastien Graulich (UNIGE) Jun 2009

EPICS Data Server

(Single ‘status’ PV)DATE Client


Network Status

• Need to verify that all machines on DAQ & control networks are functional throughout MICE operation

• Two types of machine

– Generic PC (Linux, Windows)

– ‘Hard’ IOC (vxWorks, possibly RTEMS)

• EPICS Network Status server contains one status PV for each valid MICE IP address

Responsible for System Responsible for EPICS C&M Date Due

Anyone with a PC/IOC in the MLCR/Hall James Leaver (IC) Aug 2009


Network Status

• Read status: PC

– SSH into PC

• Verifies network connectivity & PC identity

– If successful, check list of currently running processes for required services

• Read status: ‘Hard’ IOC

– Check that standard internal status PV is accessible, with valid contents

• e.g. ‘TIME’ PV, served by all MICE ‘hard’ IOCs




Network Status

• Currently have working prototype

– EPICS server connects to PCs via SSH, checks contents of ‘key’ ID file

– Client displays status of all PCs, scans at user-specified period (with ‘check now’ override)

• Need to add service checking & ‘hard’ IOC support




Unassigned Control Systems

• The following systems currently have no allocated C&M effort

– Time of Flight System

– Diffuser

– Calorimeter system

• Request help from MICE community to identify system requirements

• Need to find additional C&M resources

– MOG operating at full capacity & no funds for DL to undertake these projects

– Expect those responsible for each system will be required to implement corresponding EPICS controls

– Assistance from FNAL Controls Group would be welcome (to be discussed)

• Work currently halted due to budget constraints

• 3 options

– Allow DL to complete project

• Requires ~£18K capital + 0.4 man years effort

– Take DL’s current design & complete within the collaboration

• Requires ~£18K capital + ~£15.2K vxWorks developer licence + 0.6-0.8 man years effort

• Insufficient MICE manpower available…

– Discard DL’s design & start over within the collaboration

• Unknown capital requirements (likely ~£18K)

• Requires ~1.5 man years effort

• Insufficient MICE manpower available…





• Only reasonable option: provide DL with funds to complete project

• Cannot pay for work out of UK budget

– Possibly utilise common fund?

• AB currently in negotiations with MZ

• Must decide on course of action (preferably before end of CM24)




H2 Absorbers: Hydrogen System

• DL have acquired necessary safety training

• Started evaluating PLC systems

• Very early stages of development

– However, full funding already allocated

– No immediate problems


Yury Ivanyushenkov; Tom Bradshaw (RAL) Adrian Oates; Graham Cox (DL) May 2010…?


RF Cavities: RF System• Andy Moss has system well under control

• Local amplifier PLC to monitor safety interlocks – software development by Chris White– When installed at RAL, intend to implement EPICS readout via Ethernet or

RS232

• Second Low Level RF (LLRF) system– Reads power levels from 3 amplifiers + cavity probe signals

– Implements amplifier drive feedback loop to stabilise RF phase & amplitude

– LLRF cards designed by Larry Doolittle (LBNL), corresponding IOC to be written by Dimity Tettyleman

• DL to build LLRF cards + IOC crate

• No contracts placed yet, but expect to test LLRF system on DL RF test stand before end of year

• Other details to be finalised


Andy Moss (ASTeC) Dimity Tettyleman (LBNL); Adrian Oates; Graham Cox (DL) Sep 2010…?

Important Points & Actions for the MICE Community


Items Which Require Action!

• Must find resources within MICE community to complete EPICS C&M systems for

– Time of Flight System

– Diffuser

– Calorimeter system

• Must resolve issue of funding for DL’s work on the Spectrometer Solenoids

• PH’s contract expires very soon…

– He is essential to success of Online Group

– If he is not reemployed, we won’t have: Alarm Handler, Channel Archiver, remote parameter monitoring, C&M systems for CKOV, Focus Coils, Coupling Coils, etc.
