CPO - 带电粒子光学模拟软件

隆重推出全新免费的CPO2D和CPO3D 64位版本

CPO软件的64位版本现已免费提供。此版本很适合学生以及希望在购买功能更强大的无限制 64 位版本之前探索软件功能的用户。

此前，仅提供 32 位版本供免费使用。鉴于 32 位应用程序的限制，我们决定不再提供任一 32 位版本。

免费版与无限制版本构建于相同的代码基础之上，无需许可证密钥或互联网连接即可安装。

请注意，免费版不包含以下高阶功能：

• 大量电极分段
• 散射
• 用户自定义阴极
• 电介质
• 场导入

如果您需要这些选项，可以在决定是否购买 CPO 软件的无限制版之前，下载15天的评估版。如须查找CPO的免费版和评估版，请及时联系我们。

解决二维和三维静电问题的前沿程序

边界元法 (Boundary Element Method, BEM) 处理表面电荷，与几乎所有其他商业程序所使用的方法相比具有诸多优势。这些程序由 Frank Read 教授和 Nick Bowring 教授在曼彻斯特大学的研究小组开发，该小组是第壹个在电子光学领域应用 BEM 的小组，并出版了权威著作《Electrostatic Lenses》(作者：Harting 和 Read)。Frank 与 Ryan O'Neill 合作，共同致力于软件的进一步开发。

这些程序被誉为带电粒子光学的黄金标准。CPO 程序精度极高，并具备许多其他程序所没有的高阶选项。如果您希望及时了解新版本发布信息，请考虑订阅我们（发布频率极低的）通讯。

CPO 程序： 

• 易于使用，配有详细的在线帮助系统
• 包含大量易于使用的选项，例如用于焦点优化的自动迭代
• 提供两个版本以满足您的需求：适用于轴对称或平面对称系统的 2 维版本 (CPO2D)，以及适用于所有其他系统的 3 维版本 (CPO3D)
• 支持对电极进行缩放、移动、旋转、拉伸、挤压、裁剪或复制及重复
• 界面很清晰完整，配有在线帮助系统和教程视频
• 提供 64 位应用程序

BEM 提供精度和灵活性：

• 无需网格或节点，仅需电极上的表面电荷
• 与其他方法相比具有诸多优势，包括精度和速度
• 大量基准测试证明其高精度和高可靠性
• 根据形状自动细分电极
• 很适合在存在更大电极的情况下处理微小电极

强大的空间电荷和阴极版本：

• BEM 很适合处理空间电荷和阴极，因为 BEM 是基于电荷的方法
• 可以轻松定义任一形状和尺寸的阴极
• 提供多种不同阴极发射类型的菜单选项，从热离子发射到场致发射
• 也支持用户自定义发射特性
• 处理全局空间电荷扩散以及粒子间的随机散射
• 采用谨慎且成功的阻尼迭代方法

World-beating programs for solving 2 and 3-dimensional electrostatic problem

The Boundary Element Method, BEM, deals with surface charges and has many advantages over the methods used in almost all other commercial programs. The programs were developed by Profs Frank Read and Nick Bowring, in the group at Manchester University which was the first to use the BEM in electron optics and which produced the definitive book Electrostatic Lenses, by Harting and Read. Frank has been joined by Ryan O'Neill, working on the further development of the software.

The programs have been described as the gold standard of charged particle optics. The CPO programs are exceptionally accurate and have many advanced options that are not present in other programs. If you would like to be kept up to date with new releases, please consider subscribing to our (very infrequent) newsletter .

The CPO programs:

• Are easy to use and have a detailed and comprehensive on-line help system
• Feature a large number of easy-to-use options, such as automatic iteration for focus optimization
• Tailored to your needs with a 2-dimensional version (CPO2D) for axial or planar symmetry, 3-dimensional version (CPO3D) for all other systems
• Enable manipulation of electrodes that can be scaled, moved, rotated, stretched, squashed, cropped or copied and repeated
• Very clear and comprehensive with an on-line help system and tutorial videos.
• Available as a 64-bit application.

The BEM provides outstanding accuracy and flexibility:

• No mesh or nodal points, only surface charges on electrodes
• Many advantages over other methods, including accuracy and speed
• Large number of benchmark tests to prove high accuracy and reliability
• Automatic sub-division of electrodes to suit shape
• Ideal for for small electrodes in the presence of much larger electrodes

Powerful Space-Charge and Cathodes versions:

• BEM is ideally suited for space-charge and cathodes, since the BEM is charge-based
• Cathodes of every shape and size can be easily defined
• Menus for several different cathode emission types, from thermionic to field-emission
• User-defined emission properties also available
• Deals with global space-charge spreading and also particle particle stochastic scattering
• Careful and successful method of damping iterations
