Manfreds upgrade proposal for ring-BPM down converter BPM hardware tunnel and three reasons extend the dynamic range single bunch and multi-bunch integrated - selectable gain commissioning; service and maintenance remote read-out for each downconverter calibration signals online remote controlled calibration signals goals for Nov.Dec run one upgraded module, downconverter minimum LabVIEW based test shotware no EPICS integration miner improvements at ATF site beam position signal processing 27um/0.1dB fitted by polynomial - compensating drift of gains calibration scheme +/- 714 Mhz - fieldbus wiring 24/32 modules will be used 12-bit ADC monitor voltage, temp, LO level SPI1 change freq. of PLL working on "draft" we are busy hardware components calibration signals controlled by PLL software components micro-computer present status CAN bus micro-computr firmware with help from Jlab questions prototype test at FNAL, then production Q : tones ? A : 2 tones zero off-set, no four tones required Tonee SLAC ring BPM upgrade button signals 63 BPMs 4 VME crates Q : DIO why we need digital-IO A ; not needed Q : 5000$/board ? A : 5 boards , i.e. 1000/board proposal additional exp. in December near the Septums Q : cost 3000/64 cable expensive ? A : robust, reliable installation ( answered by Doug ), will look for cheaper cables Q : 2nd stage, early/late spring? Is it match to FNAL A : complete sytem 64 BPMs ? concentrate Nov/Dec run, now, if we find any problem, we need changes A : this is optimistic schedule ( minimum ) A : we need/complete before the ATF2 beam, but it is optimistic C : operation svhedule can be seen from the webiste Q : in December, there are three weeks ? A : Yes, installation in one week and 2 weeks for work A : we we try two weeks (FNAL(, some come early, some come later hardware test, FNAL interest also in beam test A : test in early November to finalize the design, FNAL-SLAC module Tonnee, janice come to FNAL for collaboration Q When review ? A after the ATF test, fixed almost all design; will be in next 2 weeks early december, we need review, for new funding Q Terunuma-san : where they (boxes9 are mounted A it may be girders A we need something of holders,, glue with epoxy A will work on layout, some may be merged into box Q access to BPMs near septums A QM7 can be accessed A kicker noise must be lower, it can not transfer in the cable A we will test it. wire scanner 3D deawings are shown firs one is vertical wire scanner 100nm steps, horizontal and 45 degree wires 4um wire of vertical, others are 20um. 180mm long A 100 from IP should be further moved ? 490mm ? C first tuning, big work -> wire scannerを取り除いて調整すること。 Q : IPでmicron sizeのとき、carbon wire ではどれくらいか？ A : mm size Q : commissioning strategy ? A : C-wire, Honda monitors で 500nmまで調整すれば、final-Qでβを調整すればIPで500nm程度になる Q : errors ? A : position, rotation , 6-poleで調整
