h1. Presentation Materials:
[CDR Presentation, M. 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
