The goal of this project is to develop a silicon pixel detector for measuring the beam profile of a room-temperature linear collider that was proposed by Japan and the United States. First, the proof of principle was demonstrated by simulation. A prototype sensor was designed and produced in collaboration with Sherwood Parker of University of Hawaii. The readout chip was designed by this group and fabricated by ROHM through VDEC. The timing resolution achieved 30ns, and the radiation tolerance was proved up to 2 Mrad using the Co60 source at the engineering department of Tohoku University.The next step was to produce a readout chip that can be bump bonded to the sensor. In August 2004, however, ITRP (International Technology Recommendation Panel) has decided that the International Linear Collider be based on the super-conducting technology Since the hit count per beam train for the linear collider based on the super-conducting technology is 20 times larger than that based on the room-t … More emperature technology, the original circuit design would result in occupancy of order unity. This led us to adopt a scheme where the long beam train is divided to 20 time slices and the counts are read out during the gap of the beam train. The design was completed in 2005 and submitted to VDEC for production of a prototype. The prototype was fabricated and delivered to Tohoku University at the end of 2005. The status report was presented at the International Linear Collider Workshop at Snowmass, Colorado, USA in August 2005. The test system had been developed in parallel with the chip production, and the test revealed a problem at the input polysilicon resister. After extensive tests involving X-ray analysis, Electron Beam Analysis, and Focused Ion Beam, the problem at a few of the input resisters were fixed and a part of functions have been verified. After discussions with companies, it became clear that the reason for the problem was a bug in the program certified by the foundry (TSMC) to check the design rule. We have re-submitted the read out chip after necessary modifications. The design and fabrication of the chip are described in the paper 'Pixelated readout circuit for pair monitor at international linear collider'. In parallel with these studies, a simulation study was performed to see if the beam profile can be measured for the case of a large beam crossing angle. The study found that the measurement is possible even though the accuracy degrades compared to the head-on collision case, and the result has been published as a paper. Less

该项目的目标是开发一种硅像素探测器，用于测量由日本和美国提出的室温线性对撞机的光束轮廓。首先，通过仿真验证了原理的正确性。与夏威夷大学的舍伍德·帕克合作设计并生产了一个原型传感器。读出芯片由本课程组自行设计，由ROHM公司通过VDEC制作。采用东北大学工程系的Co60源，时序分辨率达到30ns，辐射容限达到2mrad。下一步是生产一个可以与传感器碰撞连接的读出芯片。然而，2004年8月，ITRP（国际技术推荐小组）决定国际直线对撞机采用超导技术，因为基于超导技术的直线对撞机的每束列车撞击次数是基于室温技术的直线对撞机的20倍，更多的温度技术，原有的电路设计将导致占用顺序统一。这导致我们采用了一种方案，将长波列分成20个时间片，并在波束列的间隙读取计数。设计于2005年完成，并提交给VDEC生产原型机。原型机于2005年底制造并交付给东北大学。该现状报告于2005年8月在美国科罗拉多州斯诺马斯举行的国际线性对撞机研讨会上发表。测试系统与芯片生产并行开发，测试发现输入多晶硅电阻存在问题。经过广泛的测试，包括x射线分析、电子束分析和聚焦离子束，几个输入电阻的问题得到了解决，部分功能得到了验证。在与公司讨论后，很明显，问题的原因是由代工厂（台积电）认证的程序中的错误，以检查设计规则。读出芯片经过必要修改后，我们重新提交了。本文介绍了该芯片的设计和制作方法，并在“国际直线对撞机对显示器像素化读出电路”中进行了阐述。在进行这些研究的同时，还进行了模拟研究，以确定在大光束穿过角的情况下是否可以测量光束轮廓。该研究发现，与正面碰撞相比，即使精度降低，也可以进行测量，结果已作为论文发表。少
