	A maximum of the light emission can be seen on one side of the scintillator sheet. This is due to an angle between the MAPS sensor and the scintillator sheet: The right edge is closer to the sensor then the left edge of the scintillator. In addition, another defect pixel row can be identified on the lower right hand side of the image.		A maximum of the light emission can be seen on one side of the scintillator sheet.

	The border between the two MAPS sensors can be identified easily. There is a small shift between both sensors, resulting in a shift in the centre of the image. In addition, a small gap between the two sensors can be seen. This is due to the five defect pixel rows at the upper edge of the lower MAPS sensor.

	The MAPS sensor has to be set up in a light-tight box. Connect the board to the Multiplexer and the Multiplexer with the computer, using the labeled cables. "Full" has to be connected with port 1 on the computer. Remove the the aluminum foil in front of the sensor. It is important not to touch the MAPS sensor, especially while taking pictures when the bias voltage is switched on. Doing otherwise might destroy the sensor! Turn on the board and the multiplexer. Connect the LED with the scintillator sheet. Place the scintillator sheet in front of the sensor, the unwrapped side pointing towards it. Switch on the LED board. Set the settings of the LED, e.g. frequency=100kHz, pulse length=30ns, bias voltage=5V. Then switch on the LED.		The MAPS sensor has to be set up in a light-tight box.
