Introduction

Control system will evolve with machine needs

Control system commissioning needs to be incorporated in the schedule

Need to prioritize control system needs Which devices need to be read/controlled

High Level Applications

The controls software used by physicists and accelerator operators to:

will be EPICS control panels (edm)

keep the beam running stably in the optimized state

tune or optimize the beam

monitor performance for long-term optimization

diagnose problems with machine performance

detect, prioritize and notify of fault conditions

Closer look at data archiver3 types of data to archive

signals from BPM and other gated devices (N scalers with timestamp). N=160 BPMs*3 + 9 toroids + 19 wire scanner readout devices + other devices (beam loss monitors and ion chambers)

video data (15 frames/sec of 1 Mpixel data), 1 camera at a time

machine parameters and ambient conditions (10K channels with timestamp, once a minute)

What is needed here?160 BPMs synchronously at some rate? Forever. 1Hz, 10Hz, 20 Hz?

What about archive viewing?

Any need to keep circular buffers and trigger them on some event? Like an MPS trip?

Areas of Concern 1

Matlab vs XALMatlab is needed for physicists to create on-the-fly applications. Direct access to control system parameters with time stamps will be provided.Which operator applications might be done in Matlab or XAL? Who should participate in the decision? When do we need to decide?Chris Allen (LANL) giving presentation “Automated Charged Particle Beam Steering” (XAL) Thurs. Sept.30, 2-4 p.m. SSRL 3rd floor

Areas of Concern 2

What are we using for a relational database (RDB)?

Needed for configuration control and online modeling

We are late getting started on this

There is still no money to start it

Dayle Kotturi


September 23, 2004

Areas of Concern 3

The Control System needs time for Commissioning!!

Make subsystem schedules with time for this

Provide support for operating the equipment to ensure proper operation through the control system.

Dayle Kotturi


September 23, 2004

ConclusionsThe control system architecture supports the requirements.

Information is needed from the project regarding the dates the equipment is required.

To support commissioning tools, we must get some resources to support RDB and determine a platform for these tools.

Information is needed to ensure that data acquisition system supports the requirements

Subsystem engineers must include time to commission the control system.

Information is needed from the physicists regarding what tuning scenarios they will need so that the appropriate application software is avail (e.g slice emittance msmt).

A channel access server in SLC provides data from existing SLC micros to EPICS applicationsAll IOCs have both a channel access server to allow access and a client to have accessChannel access provides read/write by all clients to all data with a server.All EPICS high level applications are channel access clients that may or may not have a server.

Fast Feedback

Fast feedback is required to run at 120 HzValues will be transmitted from RF and selected diagnostics to Power Supply and RF IOCsThe communication needs to be reliable, verifiable, and have a well thought out degradationThe entire time budget to read, transmit, commute, control, and settle is 8.3 msecFirst estimates are that the control system can use 2 msecs to transmit and receive the dataCan this be done over a common Ethernet with adequate bandwidth – or is a dedicated one needed?

DriveLaserOff

Machine protection is used here to define faults requiring global mitigationResponse time is under 8 msecThere are two mitigation devices:

Single Beam Dumper - which prohibits the beam from entering the undulatorDrive Laser Off – which prohibits beam from entering the cavity

Action must also be taken to reduce the repetition rate of the beam

This new design is required to interrupt the beam before the next beam pulse.
