EPICS channel (PROPERTY) |
DESCRIPTION |
EPICS record type |
$(SEC):FF-X-REQ |
horizontal feed forward request (enable request) |
bo |
$(SEC):FF-X |
horizontal feed forward granted (indicates FF activity) |
bi |
(SEC):FF-Y-REQ |
vertical feed forward request (enable request) |
bo |
$(SEC):FF-Y |
vertical feed forward granted (indicates FF activity) |
bi |
$(SEC):FF-CORR-SEL |
select corrector for feed forward; corr. magnets are selected by ascending numbers within a sector (1..7) |
ao |
$(SEC):FF-BPM-SEL |
select BPM for feed forward readback; BPMs are selected by ascending numbers within a sector (1..7) |
ao |
$(SEC):FF-COUNTER |
feed forward counter; indicates present position within the feed forward table |
ai |
$(SEC):FF-COUNTER-C |
clear feed forward counter; (reset to zero) |
ao |
$(SEC):FF-SCALE-X |
horizontal scaling factor for feed forward table; normalized feed forward tables are multiplied by this factor, the result is interpreted as A (Ampere) and directly added to the corrector current output |
ao |
$(SEC):FF-SCALE-Y |
vertical scaling factor for feed forward table; normalized feed forward tables are multiplied by this factor, the result is interpreted as A (Ampere) and directly added to the corrector current output |
ao |
$(SEC):CORRX-FF |
horizontal feed forward table (normalized); 4066 elements |
aao |
$(SEC):CORRY-FF |
vertical feed forward table (normalized); 4066 elements |
aao |
$(SEC):WF-CORRX-FF |
scaled horizontal feed forward table ($(SEC):CORRX-FF x $(SEC):FF-SCALE-X); 4066 elements |
waveform |
$(SEC):WF-CORRY-FF |
scaled vertical feed forward table ($(SEC):CORRY-FF x $(SEC):FF-SCALE-Y); 4066 elements |
waveform |
$(SEC):WF-BPMX-FF |
horizontal, synchronous BPM reading of BPM no. $(SEC):FF-BPM-SEL; 4066 elements |
waveform |
$(SEC):WF-BPMX-FF |
vertical, synchronous BPM reading of BPM no. $(SEC):FF-BPM-SEL; 4066 elements |
