Revision as of 10:21, 14 December 2016
We will meet Wednesday Dec 14 @ 10am in TL-1227 for final updates.
Status Updates
- Joe - Schedule
- Winter SAD
- Tomasz - LLRF upgrade status
- Rama/Chad - Firmware
- progress on firmware
- 1.PC104 breakout board was tested and is being used with Scott's software and the communication between EPICS and FPGA looks good
- 2.FPGA is talking to DAC (4-channel), ADC(4 channel) and PC104.
- 3.Tone mode functionality needed for January is now working. Magnitude and Phase can be set to 4 DAC channels individually from EPICS PVs
- 4.Magnitude and Phase measured from ADC channels is displayed in EPICS
- 5.ADC and DAC have enough resolution for control when needed (0.2 degree resolution for phase and 0.5% for magnitude), so there is no need for an extra clock board
- tasks in progress for January
- 1.replacing 4 channel ADC board with 8 channel ADC board. Not needed for January, but will install once testing is done in next couple of days. This will give us the ability to scan all the channels (4 lasers, 70 MHz, 35 MHz)
- 2.work on screens for OPS
- 3.procedure for correcting phase, if the phase changes in either 35 MHz or 70 MHz (EPICS level)
- 4.testing with RF board once the chassis is assembled (in progress)
- 5.continuing firmware development
- Scott - Software
- Dave/Manuel - Hardware
- Dave - Documentation/Drawings
- Michael/John - Current control and remote operation of laser amplifiers
- Michele - 4-laser HLAPP => Application ready to test.
