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
