Proton Calorimetry/Experimental Runs/2017/Aug10-31

Experimental tests with Nuvia 3mm scintillator sheets and Pravda CMOS stacked sensor.

Set-up of MAPS

This section contains the instructions to take images with the MAPS sensor developed for the PRaVDA collaboration. In order to use the MAPS sensor, three components are essential:

• MAPS sensor integrated in board
• Multiplexer
• Computer with aSpect software

Then follow these steps:

• Launch computer. Password: aSpect
• Window will open automatically. In "Drive U Substitution" select first entry. Then press "substitute".
• Open "IDMate":
  • In "DUT Grap" (find it in upper left corner) select "Init Testsystem" and press "play" button.
  • TCP will show error message.
  • Set settings:
    • n21: Stream_master: value=1
    • n32: CB111_En: value=1
    • n46: BeamClk_En: value=0
  • Confirm by pressing "Set all"
  • Select "DUT init CT mode" and press play button.
  • To record frames, select "Streaming Start" and press play. It will ask you to select a file name. After confirmation, frames are recorded.
  • More important settings:
    • n24: Set saving path for file.
    • n26: Stream_repeats: set number of frames. "0" equals one frame, "1" equals two frames, etc.
    • n28:Stream_daqtime: integration time of sensor in seconds. Must be an integer between 1 and 6.
  • To exit IDMate, select "DUT Exit" and press play button.
• Files are stored in a binary format. In order to have a quick look at the output, use "Pravda file viewer".
  • Select file in upper bar. Then press "Read file".
  • Select "Image" button to see visualisation of the binary data.
  • There is the possibility to export the data as .txt file or .tif image.
