Attendees: | Steve Smith | John Dusatko | Tim Montagne | | Hamid Shoaee | David Dowell | Sheng Peng | | Mike Browne | Arturo Alarcon | Stephen Norum | | | Michael Cecere | | h1. Agenda: # *Injector Install Solution*: What circuitry will be ready for Injector Install? # *System Architecture*: Imaging requirements? MPS EPICS dependency? h1. Action: (summary; see details below) # *M. Cecere* Pursue an Analog Electronics solution for Injector Install. # *M. Cecere* Determine MPS requirements, Interim and Permanent. # *D. Dowell* Send revised Toroid specifications to M. Cecere # *M. Cecere* Investigate network BW options for sending video/waveform data (from waveform imaging) back to MCC. # *M. Cecere* Develop ESD based on Analog Interim Solution for next week h1. Minutes: # *Discussed Digital FPGA/DSP Design* ## Has many nice features: ### Beam Charge Determination ### EPICS Independence for MPS signal generation ### Complete waveform imaging capability ## Steve thought this project could be done in 6 months, if enough resources were dedicated. This was judged risky at this time. # *Pre-Amp might not be needed at all* ## it was briefly mentioned that the pre-amp can be elliminated from this design and it's functions (calibration pulse generation, possible pulse stretching/conditioning) can be subsumed by the electronics board itself. # *MPS Requirements* ## Comparator mode and Single Toroid modes both needed. ## Need independence from EPICS processing for reliability. ### This requires remebering MPS threshold values in case the host IOC locks-up. ### and a watchdog timer so Toroid board can notify MPS of problem. # *Imaging Requirements, Still needed for Toroids?* ## If toroid designed to spec, it should provide a recoverable image of the dark current pulse. ## Dave says this requirement can be dropped for toroids, will rely on Faraday cups for imaging needed during tune-up and diagnostics. ## Therefore, Imaging requirements still needed for Faraday cup. ### can be supplied by an analog signal tap that can be fed to an o-scope or digitizing card for readback over the network. ### need to investigate network BW options for sending imaging data (video signals, digital waveform data...) back to MCC for remote observation. # *Interim Analog-based Solution* ## can still supply imaging requirements ## MPS signal generation needs made much more difficult without the presence of digital electronics on board. adding digital electronics complicates project timeline. ### relax MPS requirements for Interim, injector install solution? |
