The protection of the PVSS-based Human-Machine-Interface parts of the Control Systems for the LHC accelerator and the experiments at CERN is implemented using the JCOP Framework Access Control component. It allows to protect from non-malicious activity (such as misuse due to operator's mistake) by enabling/disabling the elements of the User Interface. It extends the native PVSS mechanisms for user-authentication and makes the management of the role-based authorizations easy to configure and maintain. Ultimately, it enables the synchronization of the access-control related data across distributed systems, and allows to synchronize this data with central user-management resources at CERN (such as Active Directory), and automated creation of user accounts.

The LWDAQ (Long-Wire Data Acquisition) software and hardware from Brandeis University, Mass., USA provides access to a powerful suite of measurement instruments. Two high precision monitors used to measure the relative alignment between a source and a sensor are included. The BCAM cameras take images of point light sources and the Rasnik cameras take images of the NIKHEF developed Rasnik mask. Both systems are used in the LHC experiments at CERN. Brandeis University provides a tool called Acquisifier to script the data acquisition process and to analyse the images to determine the alignment data. In order to incorporate the resulting data from the alignment system into the Detector Control System (DCS) of the LHC experiments a new software component of the Joint COntrols Project (JCOP) Framework was developed. It provides a TCP/IP interface between LWDAQ and the SCADA tool PVSS so that the results of the data acquisition process can easily be returned to the DCS. This new component simplifies the generation of the Acquisifier data acquisition script, controls the run mode of the Acquisifier and collects the results of the acquisition.
