Beamline Controls Technical Working Group information

The BC Technical Working (BCTWG) group meets monthly to review and gather feedback on possible changes in either the way BC delivers support or the technologies that BC supports. The BCTWG comprises the BC group plus interested stakeholders from XSD. In a nutshell, the main goal of the BCTWG is to improve communication between BC and its customers on topics of mutual interest.
