Under construction, please send suggested additions to RJW.
ADC Analog-to-digital converter CD Central detector, see ID DAQ Data AQuisition system Fastbus A standard system for mounting, controlling and interfacing fast electronics for particle physics applications; historical successor to NIM and CAMAC and providing the highest density of channels per module. FDDI Fiber-optic high rate data bus for local area networks. FIFO First-in, first-out, a pipeline buffer. FSCC Fastbus Smart Crate Controller GPS Global Positioning System, a satellite system which allows receivers to compute position on earth to a few meters, and absolute UTC to 100 nsec. ID Inner Detector (or Central Detector) IRIG Standard coding system for clock data, allowing manufacturer-independent transfer of time data. LIFO Last-in, first-out, a stack buffer. OD Outer Detector (US contribution to Superk) pe Photoelectron; one photon produces 1 pe in the PMT photocathode with about 25% efficiency. PMT Photomultiplier tube TDC Time-to-digital converter UTC Universal Time (Coordinated), international standard version of GMT commonly used for astronomical event logging. VME A widely used computer bus standard which allows interfacing of external equipment to computers. VSB A less-widely used bus used for interfacing industrial equipment. WLS Wavelength shifter, a doped acrylic plate which converts UV to longer-wavelength light; used in SuperK to increase the collecting area of the relatively small OD PMTs
