Data acquisition system for the HHIRF spin spectrometer

The Spin Spectrometer at the Holifield Heavy Ion Research Facility (HHIRF) is a multidetector ..gamma..-ray spectrometer consisting of 72 separate NaI detector elements closely packed in a 4..pi.. geometry. The basic apparatus was constructed at Washington University and has been installed and implemented at the HHIRF at Oak Ridge National Laboratory. The spectrometer was designed especially for the investigation of the mechanisms of heavy-ion induced nuclear reactions and of the structure of nuclei with high angular momentum. The data acquisition system is described. (WHK)

Specifications for the Linear Charge Coupled Device for use in transient recording (open access)

Specifications for the Linear Charge Coupled Device for use in transient recording

Specifications are presented for the Linear Charge Coupled Device (LCCD) developed at the Lawrence Livermore National Laboratory for recording data from transients. This device can be used to record electrical signals at sample rates greater than 10/sup 9/ samples per second. Both electrical and physical specifications of the device are presented. The bias and drive requirements of the device are presented in tables and in timing diagrams. Typical performance data are tabulated and shown in oscilloscope photos. The physical specifications of the device include plane and cross sectional drawings of its various registers and I/O sections. Enlarged photos of the mask set are shown and all critical dimensions of the active regions are given. Finally, the impurity doping profile used for the transfer channels is shown.
