SVT Voltage Controls

• Requires two EPICS IOC: for MPOD and for DAQ interfaces.

• We borrowed an MPOD chassis with 3 bias and 3 LV boards from CLAS12 SVT group.

• We can have an IOC running on a Hall B clonioc2 server communicating with the MPOD using SNMP.

– Configured using the Hall D scheme and software.

• Detector configuration and the mapping is stored in a SQLite DB which can be used by both IOC initialization and by alarm handler configuration.

– Detector to board/channel mapping in DB is arbitrary for now.

• Pelle and Sho started work on DAQ EPICS IOC for low voltages for hybrids.

– Can successfully read the SVT temperatures into EPICS.

• Bryan McKinnon (Glasgow) has created GUIs for voltage controls.

– Made a presentation on status of SVT voltage GUIs on controls meetings.

– All bias voltages and low voltages boards are implemented.

– Voltage overview screen and the screens with voltage parameters are ready.


SVT Voltage Alarms

• HPS alarm system will be similar to that of CLAS6– Works well– Save labor

• Ani Simonyan (Yerevan) developed the alarms screens for the SVT voltages.– Autoconfiguring the EPICS

alarms with Python scripts using the channel mapping information from an SQLite database.

– No need to manually change the alarms configuration when the SQLite DB changes

• Can be integrated into a single alarm tree of HPS

SVT Motors

• HPS will require 3 new motorized axis.

• The 3 new HPS motors will be controlled by a new Newport XPS-Q8 controller.– Controller procured, cables manufactured– The rest of the standard Hall B stages will be controlled using

Hall B scheme– Can also move 3 stages to the XPS controller

• Beam blocker, beam viewer and collimator.

• New beam scanning procedure needs to be developed for SVT motors that use XPS controller– Hall D has these controllers and currently developing harp

scans using those. – Ani Simonyan (Yerevan) is working on the beam scanning

software with Hall D on SVT scan development. – Ani needs a drawing of wires w.r.t SVT to calculate the

geometry.

Beam Scans• HPS will use standard Hall B wire scans for regular beam profile harp scans.

– If time allows, can migrate to XPS-based scan

• Hall B recent scans used 3-wires for three projections: X, Y, and 450

– CLAS6 never analyzed the 3-rd wire result– Ani Simonyan is working on scans, added the fitting of the third peak– Can determine the orientation of the long axis of the beam

• The HPS SVT scans will need to utilize another procedure – Use a TTL pulse from the XPS controller to gate the scaler to synchronize the motor and scaler readout


Chillers

• SVT needs to use two separate chillers – Both will have serial communication for remote controls– Both will be instrumented for shut-off valve to be used for the

SVT interlock system.

• Wesley Moore (JLAB) will be taking over the chiller EPICS support– Wesley has significant experience with the serial communication

devices in EPICS

• One chiller (small SVT chiller for FE boards) is at JLAB.– Current being used by ECAL.– Wesley will start work on EPICS support probably next week.

• The second chiller will be implemented when it arrives at JLAB– About two weeks of work.

• Wesley will also implement the ECAL chiller controls in EPICS.

SVT Interlocks

• Operations of SVT requires interlocks:– Shutdown MPOD power using FAST_SHUTDOWN (or ENABLE) signal when

• SVT temperature is high, or• Vacuum pressure is high, or• Coolant flow is too low in either of the two SVT chillers, or• Beam is off in Hall B (FSD feedback)

– Shutdown both SVT chillers via relay• Vacuum pressure is high

– Interlocks would be latching requiring manual reset

• We are building a system where the logic would be programmable (provided the inputs are there).

• PLC hardware has been ordered and received at SLAC– Should program it to use in August

• Need to finalize the decision algorithm to program– States of the chiller relay and chiller solenoid valves– Whether to use ENABLE or FASTSHUTDOWN on MPOD

PLC-based Interlocks

• Functional modules procured – Controller– Analog input (8x voltage or current channels) [vacuum, flow, beam loss]– RTD input (6x RTD channels) [SVT temperature]– Digital output (16x 24 VDC channels) [solenoid valves]– TTL output (16x TTL ) [MPOD interlock]– Relay output (16x relay channels) [solenoid valves]

I/O Modules

• The timing requirements from the SVT group are not very strict, on the order of 200ms.

• Current design based on Allen-Bradley CompactLogix PLC chassis– Modular system, can easily add more I/O modules.– Relatively inexpensive hardware (<$10K for interlocks only).– Can program logic at any time if we have a software license.– Easily interfaceble with EPICS to see the statuses and values of the

inputs.– Hall D developed an interlock system based on A-B CompactLogix.

Allen-Bradley CompactLogix


ECAL Voltages and Temperatures

• Valery Sytnik ported the CAEN SY1527 EPICS driver to the latest version of EPICS.

• Nerses Gevorgyan is working on moving CLAS6 CAEN HV voltage application to new EPICS– Mapping of the channels– Control screen generation– Alarm configuration file generation– EPICS record DB generation

• Bryan McKinnon is developing an overview screen to be used by shift takers– Still in progress


CAEN SY1527/SY4527

ECAL Light Monitoring

• ECAL will have a light monitoring system with two custom-made controllers.– The same type as for CLAS12 Forward Tagger

• INFN/Genova is developing the firmware for the control module of the CLAS12/HPS pulsing system.

• Glasgow group developed EPICS support for the CLAS12 Forward Tagger controller and working on a monitoring procedure which we can use for HPS.– May need different type of controls screens between CLAS12 and HPS.– Will be discussed at the HPS controls meeting next week.

• The hardware and software are expected to show up at Jefferson Lab ready to be used.


Scalers

• Started work on JLAB discriminator scalers in EPICS (Sergey, Valery)– 16 x 4 scalers per board

• 2 thresholds• 2 scalers per threshold

– Use a server to collect and latch scalers– EPICS IOC and other processes can grab scaler counts

from the server– Prototype for driver already existed

• FADC250 EPICS driver will follow the same scheme– 16 scalers + 16 spectrum waveforms per board– Should be simpler than discriminator scalers.– No control/configuration from EPISC is required.

• Need to develop an HPS-specific application (EPICS channel list and GUIs) to display these scalers– Use the GlueX SQLite scheme for mapping channels.

Hall B Controls

• There are a lot of controls that existed in Hall B before HPS– Many system were taken apart during CLAS decommissioning.– Many need to be restored, then updated for newer hardware and operating systems.

• Accelerator division will take care of the beamline vacuum controls.

• Two new Hall B visitors (Valery Sytnik and Levon Hakobyan) will be working on migrating Hall B applications to newer version of EPICS and VxWorks. – A pretty long list of needed application and EPICS drivers have been determined.

• Krister Bruhwell has been working on magnet controls– Frascati magnet power supply controls have already been restored– Main dipole (pair spectrometer) power supply is next, should be simpler to restore. – Moeller magnet power supplies are considered lower priority for now.

• Krister is also restoring the motorized stages and the control boxes for the Hall B beamline components.– Beam blocker controls restored.– Five more stages to go.

• Krister will be restoring the ECAL temperature monitoring used during test run.

• We have an agreement with accelerator division to use MYA archiver for all HPS EPICS channels.


Schedule

• The slow controls schedule had to be modified due to – Actual manpower availability– Schedule changes in SVT and ECAL

• All controls components should be ready for operations at the end of September.

• Integration with the rest of the HPS components may last until end of October and even into November.

• Some of the controls components will require commissioning with or without beam.– Should be part of the commissioning plan

for parent HPS subsystems.
