Review Charge

Charge for the L1CTT upgrade system review
------------------------------------------

All of the individual boards which make up the upgrade of the L1CTT have been shown to work on the test bench and meet their design specifications. The purpose of this review is to verify that all of the parts work in concert as a system so that there are no reservations about installing the system from the technical point of view. The scope of this review includes the online software as well as the hardware.

Particular points which should be covered include:

- Communication paths: Have the transmission of data and control signals been verified across all of the relevant communication paths (host/controller, controller/DFEA2, mixer/DFEA2, ...). Are the bit error rates low enough for long-term operation? Have new cables been tested?
- Has connection and data integrity to TCC/TFW/L1Mu/L2/L3 been tested?
- Has the connection to the Cal Track Match system been tested?

- System scaling: Has it been demonstrated that multiple DFEA2's in a crate (a full crate) operate without interference?
Is the measured power consumption compatible with specification?

- Parallel chain tests: Have the parallel chain tests demonstrated that the hardware produces the expected results for doublets? singlets?

- Software tools: Has software been written and exercised which
- download the hardware
- verifies the download
- monitors the operation for errors
- compares hardware output with emulation
- unpacks the CTT data which is written to the raw data chuck
- archives/tracks history of installed firmware
- monitors the system online

- Documentation: Is there adequate documentation for
- configuring and initializing the system
- interpreting errors flagged by the monitoring utilities
- specifying the data formats
- + documentation for each piece of hardware in the system

- Installation and maintenance plans:
- have all the required safety approvals for installation been obtained, or are in the works?
_ is the installation infrastructure planned out, for example power, real estate, cabling, etc.?
- what is the installation plan and who is going to do it
- how are boards going to be repaired in the long run? Are there adequate spares and test stands?
- is it conceivable that changes might be required to hardware and/or firmware after installation and technical commissioning? How will the facilities and expertise for making these changes be available?
