PCI Board with FPGA
• I’m fighting against …
Status of Track recognition board
• The check of the connection was done.
• FPGA programming test was almost done.
• Soon , It will be connected with stage and camera …next week.
SUTS tracking with old board
• 30Hz x 140micron square
• 20cm2/h
• Angle range: theta<0.2
Z drive
30Hz ~ 100 Hz piezo drive
Track recognition test
• Microtrack level
• 1e5 track/cm2
Track density
3cm
Track density
10cm
Track density is related with air gap under the emulsion.
• Strong relation with brightness.
Brightness control by shutter
• SUTS-CMOS-Camera have electric shutter.
• Measuring the brightness every frame, feed back to shutter speed.
