Silicon Detector Lab (SDL)

Brookhaven National Laboratory (BNL)’s Silicon Detector Lab (SDL) in the Instrumentation Division is a unique facility that has been the main center for development and production of prototype radiation detectors for more than 20 years, serving the scientific community in the United States and abroad. The detectors developed in house have been used in Nuclear and High Energy Physics, Photon (Material and Life) Science and experiments for X-ray Astronomy. We are conducting the entire detector development and production, which includes the simulation of device processing and its electrical behavior, the design of the detector and its processing masks, all the detector fabrication steps (from oxidation, photolithography, …, to metallization) and detector testing and characterization, with the exception of ion implantation (service from outside with a turnaround time of a week).

Current Projects and Collaborators

1. NSLS-II







The MAIA spectroscopy system was designed to be used at the former National Synchrotron Light Source (NSLS) with an X-ray microprobe. This system is composed of about 400 individual silicon diode detectors which were fabricated in our SDL were wire bonded with the application specific integrated circuits (ASIC). This system allows scientists to perform the elemental mapping using synchrotron light source in the biological, geological, materials and environmental sciences. In order to increase its sensitivity, currently we are designing a silicon drift detector (SDD) intended to replace each individual silicon diode detector in MAIA spectroscopy system. We have gained experience in developing an X-ray spectroscopic system for NASA (founded by NASA) a few years ago which consists of pixel array of SDDs. In addition, a couple years ago we developed an Adapter Detector Concept which uses single spiral detector to bias entire array of SDDs, in which each individual SDD is concentric ring design, by double-metal configuration. The new Drift-MAIA spectroscopy detector is going to combine all the above experience from these previous projects and it will be used in the newly constructed NSLS-II in BNL.



2. APS






We are beginning to develop a new hybrid pixel detector for the Advanced Photon Source (APS), the synchrotron X-ray source at Argon National Laboratory (ANL). This is a collaborative effort between the APS Detectors Group and the ASIC Design Group at Fermi Lab for APS' upgrade. The silicon sensors were produced in our SDL for the VIPIC project which aims at the development of 3D integration technology with Fermi Lab. We were subsequently approached by ANL to participate in this hybrid pixel detector development. We are planning to design and fabricate the new concept of hybrid pixel detectors for APS upgrade of ANL.



3. RHIC Polarimeter Experiment






Brookhaven leads various technical coordination efforts for upgrade of the ATLAS detector, including constructing the new silicon tracker, liquid argon electronics, and new Muon chambers, for the Large Hadron Collider (LHC) in the Center of European Research for Nuclear (CERN). The SDL is currently evaluating the designed and fabricated 3-D trench silicon detectors for the possibility of using it in the ATLAS upgrade of LHC in CERN.
