Cost estimate submitted (seems higher than expected based on previous)
Chao:
- LLRF System Control Design mostly done (just waiting on some simulation results from Zenghai_
- Start looking into Low-level RF system from Larry
- Frequency Control in Software
- Amplitude Flatness and Amplitude/Phase Control firmware
Bo
- SSA almost ready to send out
- Klystron only needs 200W, making a 350Watt board
- Firmware/hardware ready to start development
Stephen to check project tasks with people

We will be doing the 1.5 with 1 RFSoC setup, but the rest of the system is unclear (we may as RadioBeam to do it)
Chao
- Currently working on data converter characterization
  - Will probably be done in the next month
  - Trying to determine what configuration would be ideal for the up and down conversion
  - Noise analysis
  - We need to figure what what (analog) band-pass filter we need.
- Still need to work out specifications for the algorithm (with RadioBeam + Kukhee)
Larry
- In the next month:
  - Identify digital IOs and decide if we can buy or need to make a card to accommodate
  - After Chao is done with characterization, change the firmware interface from a real-real to real-IQ conversion and then take IQ to the core
    - Need interface information from Kukhee
- Port register map to current software interface
Kukhee
- Still catching up on things
- Discuss division of firmware(?) labor with Chao
- Need to discuss firmware/software division of signal conversion with RadioBeam
  - Pulse-pulse control in firmware?
    - Present a proposal on how to do this to RadioBeam
  - Multi-cavity control in software?
Bo
- Working on SSA
  - Power supply is pulsed gate which requires a trigger
  - Will eventually need to generate an interlock signal
- Will be out on vacation 9/26-10/5
  - Kukhee and Chao to lead the meeting on algorithm discussion with RadioBeam?
Stephen
- On medical leave 9/16-10/16
- Need to get a charge number for people to use
