Context: DXS is the primary beamline where this detector will be used therefore its reequipments are considered when designing the SparkPix-S 1x4. The expected beam will be spited into two and a sketch of its dimensions when interacting with the detector is depicted below
Beam concept at the detector
Draft on the concept of beam interaction with the 1x4 carrier. Detector will be pivoted around the center axis, effectively reducing the pixel size. Vibration calculations should be analyzed considering the effective pixel size (10um)
Sensor Design
- Pixel pitch is 50um
- 1mm is the baseline but Hassan has suggested that they may want to have 500um thick sensors two

TBD

Platform
The SparkPix-S 1x4 detector is very similar to the GT readout platform and therefore we will reuse it extent possible. For examle, the digital and analog boards are 100% compatible. The carrier boards and mechanical design will need to be adapted.
100kfps DAQ support system - GT Readout Platform
- Key requirements when designing the board
- Sensor aligned with rotation axis

Mechanical
- Key requirements
- CO2 cooled
- 0 degree for cooling pipe and electronics board
- in-vacuum
- Clamping can be on the back side of the detector
- Vibration specs (usually 10% of the pixel at the angle)
- Light shield needed (at least the frame designed)
