上海光源SSRF（第三代同步辐射光源）直线加速器和增强器的束流损失监测系统

A Beam Loss Monitoring System (BLM System) can help to get the beam loss information by measuring the radiation around the beam pipe. It is useful on finding the vacuum leakage, regulating the machine operation parameters, improving the machine performance and so on.

The Shanghai Synchrotron Radiation Facility (SSRF) is a 3rd generation synchrotron radiation source facility under construction, and the booster of the SSRF is the first one built in China.

A new type BLM System is designed for the injector of the SSRF. This BLM System can get accurate information of beam loss position, and it is adaptive for the pulse radiation field around the linac and the transportation line which has a very small duty factor. The BLM System has been built and used during the commissioning of the SSRF. It is proved to be functional, and a useful tool for studying the machine status.

uC/OS-II & lwIP 在ColdFire 52235 (M52235EVB) 上的移植和应用

This is the uC/OS-II and lwIP port on MCF5523x MCU.
And, a CodeWarrior project is offered, which sets up a mini-WEB server and a TTCP test program, to show how to use lwIP & uC/OS-II together on the M52235EVB.
Users can use this project as a template.
This project was done for the Hong Kong Branch of Freescale.

Mivi2440 WindowsCE核心系统

It's based on the Samsung S3C2440A MPU, and running WidowsCE 4.2 for this moment.

This system was designed with QVGA true color LCD, micro-SD card socket, USB connections,
as well as an on-board CPLD offering pulse-accumulation functions.

This system has been successfully used in a Hand-Held Isotope Identifier product.

呵呵 自己随手做着玩玩的:)

• No external power needed
• 2:1 or 1:2 mode selectable
• 350M Bandwidth

嘿嘿 还不错吧 :P

某门课的大作业了啦(俺学生生涯的最后一门课吧,估计是~)

在sunfic的指导下 认真地作了一下,呵呵

虽然自己觉得还不够深入,但总算把数据建模、滤波反投影算法、迭代算法整个都自己编程实践了一遍

:P
