A software for managing after-hours activities in research user facilities

We present an after-hours activity management program for shared facilities, which handles the processes required for after-hours access (request, approval, extension, etc.). It implements the concept of permitted after-hours activities, which consists of a list of well-defined activities that each user can perform after-hours. The program provides an easy and unambiguous way for users to know which activities they are allowed to perform after-hours. In addition, the program can enhance its safety efficacy by interacting with lab and instrument access control systems commonly present in user facilities.
