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.
