  Most Web application users in accelerator labs understand the basics of data types and data structures. They have in-depth knowledge about accelerator physics and other engineering domains. Some even develop software applications by themselves. In the approach of user-defined web applications, a user defines her/his own web application, test and use it first before sharing it to other users. It saves the communication efforts between developers and users, reduces the time from application design to production. Most importantly, users become the owner of the application and naturally the owner of the data that the application collects and produces. This will largely improve an application's quality and user experience. At FRIB, we have been practicing this approach. One of our applications, the traveler, has been developed and operated for about three years, and used by users from various departments including cryomodule, electrical engineering, controls, and business development. The traveler application allows users to design their data collection interface in a what-you-see-is-what-you-get way, and to release it by sharing with other users and groups in the lab. We are now designing and developing a generic data store that will enable users to define their own data structure, to track structure and instance value changes, and to control the access to the data.

  High brightness injectors are increasingly pushing against space charge effects. Usually, particle tracking codes such as ASTRA, GPT, or PARMELA are used to model these systems however these can be slow to use for detailed optimization. It becomes increasingly challenging in future projects such as LCLS-II where space charge effects are still significant after BC1 and BC2 at 250 and 1600 MeV respectively. This talk will describe an envelope tracking approach that compares well against the particle tracking codes and could facilitate much faster optimization.
