Continuous Integration Using LabVIEW, SVN and Hudson

74

CERN, Geneva, Switzerland

In the accelerator domain there is a need of integrating industrial devices and creating control and monitoring applications in an easy and yet structured way. The LabVIEW-RADE framework provides the method and tools to implement these requirements and also provides the essential integration of these applications into the CERN controls infrastructure. Building and distributing these core libraries for multiple platforms, e.g.Windows, Linux and Mac, and for different versions of LabVIEW, is a time consuming task that consist of repetitive and cumbersome work. All libraries have to be tested, commissioned and validated. Preparing one package for each variation takes almost a week to complete. With the introduction of Subversion version control (SVN) and Hudson continuous integration server (HCI) the process is now fully automated and a new distribution for all platforms is available within the hour. In this paper we are evaluating the pros and cons of using continuous integration, the time it took to get up and running and the added benefits. We conclude with an evaluation of the framework and indicate new areas of improvement and extension.

This paper describes the movement control system for detector positioning based on the Roman Pot design used by the ATLAS-ALFA and TOTEM experiments at the LHC. A key system requirement is that LHC machine protection rules are obeyed: the position is surveyed every 20ms with an accuracy of 15?m. If the detectors move too close to the beam (outside limits set by LHC Operators) the LHC interlock system is triggered to dump the beam. LHC Operators in the CERN Control Centre (CCC) drive the system via an HMI provided by a custom built Java application which uses Common Middleware (CMW) to interact with lower level components. Low-level motorization control is executed using National Instruments PXI devices. The DIM protocol provides the software interface to the PXI layer. A FESA gateway server provides a communication bridge between CMW and DIM. A cut down laboratory version of the system was built to provide a platform for verifying the integrity of the full chain, with respect to user and machine protection requirements, and validating new functionality before deploying to the LHC. The paper contains a detailed system description, test bench results and foreseen system improvements.

Low Cost FFT Scope using LabVIEW cRIO and FPGA

CERN, Geneva, Switzerland

At CERN, many digitizers and scopes are starting to age and should be replaced. Much of the equipment is custom made or not available on the market anymore. Replacing this equipment with the equivalent of today would either be time consuming or expensive. This paper looks at the pros and cons of using COTS systems like NI-cRIO and NI-PXIe and their FPGA capabilities as flexible instruments, replacing costly spectrum analyzers and older scopes. It adds some insight on what had to be done to integrate and deploy the equipment in the unique CERN infrastructure, and the added value of having a fully customizable platform, that makes it possible to stream, store and align the data without any additional equipment.

Unifying Data Diversity and Conversion to Common Engineering Analysis Tools

CERN, Geneva, Switzerland

The large variety of systems for the measurements of insulation, conductivity, RRR, quench performance, etc. installed at CERN’s superconducting magnet test facility generates a diversity of data formats. This mixture causes problems when the measurements need to be correlated. Each measurement application has a dedicated data analysis tool used to validate its results, but there are no generic bridge between the applications that facilitates cross analysis of mixed data and data types. Since the LHC start-up, the superconducting magnet test facility hosts new R&D measurements on a multitude of superconducting components. These results are analysed by international collaborators, which triggered a greater need to access the raw data from many typical engineering and analysis tools, such as MATLAB®, Mathcad®, DIAdem™, Excel™… This paper describes the technical solutions developed for the data formats unification and reviews the present status.
