Cecere|http://lcls-dev:4298/tiki-download_wiki_attachment.php?attId=49] (PPT Format) [Toroid Charge Monitor Timeline, M. Cecere|http://lcls-dev:4298/tiki-download_wiki_attachment.php?attId=50] ( Project Format) h1. Minutes: # Presented MicroController based design # Discussed Analog Integrator Technique ## Dual Integrators twice as long to calibrate, change design for single integrator, staged sampling of output ## Bring in baseline and pulse signals for subtraction into PIC ## No need to bring Vcomp signal into IOC ADC # Network reprogrammability would be very useful for configuration management. (could be done with jumpers, prog header...) ## Program which toroids to compare. ## Program which toroid channels, comp channels are enabled ## Program MPS signalling thresholds Enable/Disable? # How to trigger IOC/MPS that data is ready? ## Need digital input to IOC to signal data ready on Vcharge analog lines ## Need/How to signal MPS that data has been updated? # need watchdog timer on EVR trigger arrival? ## Since Beam CAN be run in Single-Shot mode, determining a missing trigger is tricky # Faraday Cup accuracy ~10-15% # Question to Tim M., when is first articles rom ISA? # Need a Test Plan for this project h1. Action Items: # *M. Cecere:* Need ICD and Test Plan # *M. Cecere:* When is first article from ISA due? # *M. Cecere:* Check with Ron Akre on his boards' availability # *M. Cecere:* Determine handshaking scheme for IOC and MPS # *M. Cecere:* Redraw integrators with one integrator, 2 S/Hs # *M. Cecere:* Add Mechnical Box design to timeline # *M. Cecere:* Add fast digitizer coding, and coder, to timeline |
