1. Wei Wei reported the test status of the tcpx2 chip. Its behavior under the radiation source (X-ray tube) was evaluated. Both the output waveform and X-ray imaging seemed normal and agreed with the simulation. The s-curve scan program was also built. However, we found some issues of the apulse testing. The equivalent injection charge produced by the apulse was found much smaller than expected. Although this issue may not affect the normal operation, it makes the measurement of the noise and uniformity not reliable. The reason was still to be understood.
2. Tianya reported some effort of building the test setup in IFAE for the tcpx1 chip. The readout chain from the serializer was preliminary established. The precise mask function and the test with analog will be tried in the next stage.
3. Yunyun Fan reported some preparation work of the laser test platform. From the communication with the vender, the 3-axis platform seemed agreed with our requirement. We will make the order and try to setup the test environment.
4. The test firmware was released to Zhang Ying for detailed test of the analog part. We will prepare for the laser experiment, and try to do the irradiation test with necessary modification of the test PCB.
