BNDHEP Archive of ATLAS Work Calibration Databases

This site preserves the work done by Brandeis University's high energy physics electronics shop in the years 1995-2021. The acronym BNDHEP stands for "Brandeis University High Energy Physics". The site is home to the Long-Wire Data Acquisition (LWDAQ) system. It provides the LWDAQ specification, user manual, software download page, command reference, and descriptions of numerous LWDAQ devices. The site serves calibration constants for alignment devices installed in the ATLAS detector and many other experiments. The BNDHEP site and domain name are maintained and paid for by Open Source Instruments Inc., a company owned by former employees of Brandeis University. The site is accessible either with or without a secure socket layer (SSL). Access without SSL make it easier for data acquisition systems to download calibration constants automatically.
