1. Status of Electronics & Control System P J Smith University of Sheffield 16/12/2009

2. 19/06/2015University of Sheffield 2 Target Controller Hardware Single key to ‘Enable’ system Hardware for Stage 1 upgrade is now complete –May need to add extra wires if additional outputs are required – but already have 3 spare BNC’s on back panel

3. 19/06/2015University of Sheffield 3 Target Controller Firmware Core control firmware is complete & functionalCore control firmware is complete & functional Remaining work primarily involves integration of control logic & USB interface –Have demonstrated rudimentary Target operations under computer control (park/hold & start/stop actuation) –Need to expose full functionality to USB interface for integration with EPICS Also require an interlock to prevent Target Frame from lowering if Target not in hold position (& to raise Frame in the event of any serious error condition) –Logic exists in FPGA, but need to route Frame inhibit signal from MLCR to Target Frame Controller (can use existing spare cable) & build small relay switch interface –Daresbury need to update Frame Controller PLC wiring/logic – planned for January

4. 19/06/2015University of Sheffield 4 Target Controller Software Software also nearing completion –Hardware driver framework in place User interface has been defined –Have implemented all EPICS server / client functionality Tested using ‘virtual’ Target Controller Device Remaining work: implement low-level hardware driver ‘plug-in’ –Being developed in parallel with firmware/USB interface integration task

5. 19/06/2015University of Sheffield 5 ISIS BPS ISIS requires a MICE Target BPS signal –All other targets in ISIS produce them – MICE cannot be an exception Normally require a BPS to be generated from 2 signals using 2 different technologies Valid signals must be ‘hardwired’ – cannot be produced in firmware/software –Cannot use Target controller FPGA Need robust methods of checking whether Target has dropped Will require some level of redesign of Target hardware –Addition of limit switches? –Additional optical readout channel? –Have not yet commenced work on this – it will not be trivial Craig will set up a meeting early next year between Paul S & Mark Arnold, where implementation options will be investigated

6. 19/06/2015University of Sheffield 6 Schedule Plan to have Stage 1 upgrade complete & installed by end of January However, Paul S has very recently been signed off work with a back problem Currently not possible to estimate when he will be fit to return This will cause an unknown delay to the project –Cannot predict whether installation before end of shutdown will now be possible

7. 19/06/2015University of Sheffield 7 Summary Good progress with hardware, firmware & software –Remaining work primarily involves integration of firmware & software Need to implement a BPS signal – requires some Target redesign –Details to be worked out early next year Were on schedule to complete Stage 1 upgrade by end of January –Health issues mean this may not be possible (should know more by mid-January)
