1
Overall Schedule
• Finish firmware by Oct. 5
• Run cryostat/AFE-IIt/VLSB tracker readout tests
at FNAL from Oct. 8 – 19.
• Ship tracker readout system by Oct. 22
• Unpack tracker readout system at RAL by Nov. 5

AFE IIt Firmware
•
AFPGA (digitization control)– the following work and match simulations
–
–
–
–
–
–
•
Byte count
Charge and time data (pedestal noise)
Data strobe signals
Zero suppression of channels below threshold
Fast clock for channels below threshold
Use only one level of 4-level analog buffer for cosmic ray tests
DFPGA (bitmap control)
–
–
Currently, modified D0 version is being used and is suitable for cosmic ray tests
Senerath’s DFPGA code which will eventually be used for MICE
•
•
•
Has released version 6 which would also be suitable for cosmic ray tests
Will release version 7, possible final version, in a few days
If development of AFPGA/Collector/Clockgen go smoothly, we may try to include Senerath’s DFPGA code.
•
Collector (sets running modes) – have working version suitable for cosmic ray tests
•
Clockgen (enable correct operation with variable input frequency signal from ISIS)
–
–
Modifications underway
Suitable version for cosmic ray tests done
Next Steps: While working on firmware, synthesize firmware packages and set up
with VLSB modules and cryostat.

VLSB Firmware
• Finally got VLSB firmware loaded onto board.
• However, simple write to and read from registers not working.
• Signals will be analyzed starting today.
• By end of the week
– Mock triggers will be read into VLSB board
– Modifications will be tested
•
•
•
•
“Squeeze out” zeros between triggers
Fast clear of memory banks after data read into MICE DAQ
Trigger count stored in register
Start and end addresses of data stored in registers

AFE IIt Boards
•
8 boards for 2 cryostats fully tested and characterized.
•
4 boards assigned to 3rd cryostat, not yet tested and characterized
• 11 spare boards available, 4 of which will be assigned to 4th cryostat.
• 23 AFE IIt boards available for MICE
• Malcolm has prepared document with board testing/characterization
procedures for Bill, Kwame, and me.
• Russ Rucinski indicated that cryostat to be ready in ~ 1 week.

VLSB Boards
• Parts and boards are at FNAL.
• Technicians have started stuffing boards.
• First few boards may be done in ~ 1 week.
• FNAL will test basic functionality of data registers.

Summary
•
AFE IIt firmware now in testing stage on test board.
–
–
–
–
•
AFPGA, DFPGA, and Collector codes done other than possible debugging
Clockgen firmware suitable for cosmic ray tests done
Synthesis with each other and with cryostat
Goal to finish and synthesize by Oct. 5
VLSB firmware uploaded onto board,
–
–
Problems writing to and reading from registers being worked out.
After that, tests of modifications should be straightforward.
•
VLSB board construction underway
•
AFE IIt board testing/characterization ongoing
•
AFE IIt and VLSB data format documentation has been updated.
