Agenda: # *D. Dowell*: Toroid Physics Requirements Review # *T. Montagne*: Toroid Mechanical Design Update # *M. Cecere*: Hybrid Electronics Design h1. Presentation Materials: [Hybrid Electronics Presentation, M. Cecere|http://lcls-dev:4298/tiki-download_wiki_attachment.php?attId=43] (PPT Format) h1. Minutes: # *D. Dowell- Design Requirements* ## Don't need to lift design requirement for waveform transfer ### Will be available on all installations, Toroids and Faraday Cups ## Asked for 500MHz BW monitoring abilities, ### Presented solution will offer 130MHz sampling rate, which will be good for waveform acquistion and charge determination ### If this isn't sufficient for diagnostic purposes a fast O-scope can be utilized at that location # *T. Montagne- Mechanical Design Status* ## More information available at tomorrow's (5/11/06) FDR ## Will be 12 turns on primary ## Not sure of calibartion coil single turn manifestation # *M. Cecere- Hyrbid Electronics* ## Presented Hybrid solution design including Analog Electronics and Digital Electronics section for waveform capture/transfer ## Analog Design- ### two possible manifestations, Time-slice integration, or BW seperation of component signals. ### decided to stick with Integration technique ### Serial link type still in discussion. RS-232 not attractive to anyone. possibly I2C would be functional. ### question raised if the digital acquisition board could be used as a communication channel. but this function would require that that board always be present, and represents a a circular route of commands/data from BCM host IOC ## Digital Electronics ### Use Ron Akre's 4 channel 130MSPS ADC board with EPICS IOC host for waveform acquisition and network transfer. ### Board could also be used to calculate beam charge, Coldfire processor fast enough for this application. #### signal would need to be stretched for this purpose, no problems here ## Analog Board and Digital Board can be put in the same box or kept in two seperate, 1u high boxes, immediately adjacent to the IOC crate h1. Action Items: # *M. Cecere* Check with B. Fuller on rack positions and locations and wiring. # *M. Cecere* Determine host IOC ADC requirements. # *M. Cecere* Determine communication link between host IOC and FPGA on analog Board # *M. Cecere* Check with Ron Akre on availability of his 4-channel board # *M. Cecere* Develop Analog Electronics design details |
