Study of pixel vertex detector with SOI technology towards the first realization

首次研制了采用PIXOR读出方案的硅绝缘体像素探测器，并对其性能进行了表征。PIXOR是一种提高位置分辨率和减少读出通道数的读出方案，我们使用第一个芯片PIXOR 1观察到X和Y通道读出几乎相同的电荷，证明了PIXOR读出方案的核心。对PIXOR 2芯片中的数字读出电路进行了验证，证实PIXOR 2芯片具有足够的功能和读出速度，可以用于贝儿II实验;并在PIXOR 1和PIXOR 2的基础上开发了PIXOR 3芯片，验证了PIXOR 3芯片在贝儿II实验中的实用性。

Silicon-on-Insulator pixel detector which equips new readout scheme called PIXOR was developed for the first time, and was characterized. The PIXOR is a readout scheme to improve the position resolution and reduce the number of readout channel.We observed using the first chip PIXOR1 that almost same charges are readout by X and Y channels and prove the core of PIXOR readout scheme. We also checked digital readout circuit in PIXOR2 chip and confirmed that PIXOR2 has enough functionaries and readout speed to be used for Belle II experiment.PIXOR3 were developed based on PIXOR1 and PIXOR2 to check the chip is useful for Belle II experiment.
